Figure 1 ­ Hardware Functional Block Diagram
The High Temperature 2 Input 2 Output controller is a highly configurable controller with versatile control of 2 universal inputs and 2 proportional valve outputs. Its flexible hardware design allows the controller to have a wide range of input and output types. The sophisticated control algorithms/logical function blocks allow the user to configure the controller for a wide range of applications without the need for custom firmware.
The 2 universal inputs can be configured to read analog signals: Voltage, Current, and Resistance as well as digital signals: Frequency/RPM, PWM, and Digital. The inputs are described in more detail in section 1.2.
Similarly, the 2 outputs can be configured to different types: Proportional Current, Voltage, PWM, Hotshot Digital Current and Digital (ON/OFF). Each output consists of a high side half-bridge driver able to source up to 2.5Amps with hardware shutdown at 4Amps. The outputs are described in more detail in section 1.4
The controller also offers a variety of logical/mathematical functions blocks that can be used to perform application-specific logic or calculations. These functional blocks are explained in more detailed in section 1.5 through section 1.9

Preliminary User Manual UMAX023220. Version: 1.1

4-52

All inputs, outputs and logical function blocks on the unit are inherently independent from one another, but can be configured to interact in a large number of ways with each other.
The different blocks described above are configured through a Windows-based Axiomatic tool, the Axiomatic Electronic Assistant (EA), via CAN using a USB- CAN converter device (PN: AX070501). Configurable parameters (setpoints) changes made to the High Temperature 2 Input 2 Output controller can be saved in a file (using the Axiomatic EA) in order to easily replicate the configuration in any other High Temperature 2 Input 2 Output controller. Axiomatic Electronic Assistant setpoints are described in more detail in sections 3 and 4.
1.2. Universal Input Function Block
The controller consists of two universal inputs. The two universal inputs can be configured to measure voltage, current, resistance, frequency, pulse width modulation (PWM) and digital signals.

1.2.1. Input Sensor Types
Table 1 lists the supported input types by the controller. The Input Sensor Type parameter provides a dropdown list with the input types described in Table 1. Changing the Input Sensor Type affects other setpoints within the same setpoint group such as Minimum/Maximum Error/Range by refreshing them to new input type and thus should be changed first.
0 Disabled 10 Voltage 0 to 1V 11 Voltage 0 to 2.5V 12 Voltage 0 to 5V 13 Voltage 0 to 10V 20 Current 0 to 20mA 21 Current 4 to 20mA 30 Resistive 30Ohm to 250kOhm 40 Frequency 0.5 to 50Hz 41 Frequency 10Hz to 1kHz 42 Frequency 100Hz to 10kHz 50 PWM Low Frequency (<1kHz) 51 PWM High Frequency (>100Hz) 60 Digital (Normal) 61 Digital (Inverse) 62 Digital (Latched)
Table 1 ­ Universal Input Sensor Type Options
All analog inputs are fed directly into a 12-bit analog-to-digital converter (ADC) in the microcontroller. All voltage inputs are high impedance while current inputs use a 249 resistor to measure the signal.
Frequency/RPM or Pulse Width Modulated (PWM) Input Sensor Type are connected to the microcontroller timers. Pulses per Revolution setpoint is only taken into consideration when the Input Sensor Type selected is one of the frequency types as per Table 1. When Pulses per

Preliminary User Manual UMAX023220. Version: 1.1

5-52

Revolution setpoint is set to 0, the measurements taken will be in units of [Hz]. If Pulses per Revolution setpoint is set to higher than 0, the measurements taken will be in units of [RPM].
Digital Input Sensor Types offers three modes: Normal, Inverse, and Latched. The measurements taken with digital input types are 1 (ON) or 0 (OFF).

1.2.2. Pullup / Pulldown Resistor Options
In all Input Sensor Types: Frequency/RPM, PWM, Digital, the user has the option of three (3) different pull up/pull down options as listed in Table 2.
0 Pullup/Pulldown Off 1 1k Pullup 2 10k Pulldown
Table 2 ­ Pullup/Pulldown Resistor Options
In order to create Active High’/’Active Low’ configurations ­ a proper combination of Digital Input modes: Normal, Inverse, Latched and Pullup/Pulldown Resistor: 1k Pullup, 10k Pulldown needs selected. For example when using afloating’ input, in order to create an `Active Low’ configuration use Pullup/Pulldown Resistor: 1k Pullup and Input Sensor Type: Digital (Inverse). The pullup resistor will create a 1 (ON) value when the input is floating. Since it is placed in Digital (Inverse), this value will be considered as OFF. Once the input is grounded this will create a 0 (OFF) but since the input is Digital (Inverse) this be considered as ON.

1.2.3. Minimum and Maximum Error/Ranges
The Minimum Range and Maximum Range setpoints are used to create the overall useful range of the inputs. For example if Minimum Range is set to 0.5V and Maximum Range is set to 4.5V, the overall useful range (0-100%) is between 0.5V to 4.5V. Anything below the Minimum Range will saturate at Minimum Range. Similarly, anything above the Maximum Range will saturate at Maximum Range. The other two setpoints, Minimum Error and Maximum Error have to be lower than the Minimum Range and the Maximum Range setpoints, respectively. Anything below the Minimum Error or above the Maximum Error will create a fault. If that input is commanding an output, the output will shut off. If requiring the output to remain active, the Minimum Error/Minimum Range and Maximum Range/Maximum Error should be set to the same values. Refer to Section 1.13 for diagnostics that can be associated with Input Function Block

1.2.4. Input Software Filter Types

All input types with the exception of Digital (Normal), Digital (Inverse), Digital (Latched) can be filtered using Filter Type and Filter Constant setpoints. There are three (3) filter types available as listed in Table 3.

0 No Filtering 1 Moving Average 2 Repeating Average
Table 3 ­ Input Filtering Types

Preliminary User Manual UMAX023220. Version: 1.1

6-52

The first filter option No Filtering, provides no filtering to the measured data. Thus the measured data will be directly used to the any function block which uses this data.
The second option, Moving Average, applies the `Equation 1′ below to measured input data, where ValueN represents the current input measured data, while ValueN-1 represents the previous filtered data. The Filter Constant is the Filter Constant setpoint.
Equation 1 – Moving Average Filter Function:

ValueN

=

ValueN-1 +

(Input – ValueN-1) Filter Constant

The third option, Repeating Average, applies the `Equation 2′ below to measured input data, where N is the value of Filter Constant setpoint. The filtered input, Value, is the average of all input measurements taken in N (Filter Constant) number of reads. When the average is taken, the filtered input will remain until the next average is ready.

1.3. Internal Function Block Control Sources

The High Temperature 2 Input 2 Output controller allows for internal function block sources to be selected from the other function blocks supported by the controller. As a result, any output from one function block can be selected as the control source for another. Keep in mind that not all options make sense in all cases, but the complete list of control sources is shown in Table 4.

Table 5 ­ Control Source Number Options

If a non-digital signal is selected to drive a digital input, the signal is interpreted to be OFF at or below the minimum of selected source and ON at or above the maximum of the selected source, and it will not change in between those points. Thus analog to digital interpretation has a built in hysteresis defined by minimum and maximum of the selected source, as shown in Figure 2. For example Universal Input signal is interpreted to be ON at or above Maximum Range and OFF at or below Minimum Range.
Control Constant Data has no unit nor minimum and maximum assigned to it, thus user has to assign appropriate constant values according to intended use.

1.4. Output Drive Function Blocks
The controller consists of 2 proportional truly independent outputs. Each output consists of a high side half-bridge driver able to source up to 2.5Amps. The outputs are connected to independent microcontroller timer peripherals and thus can be configured independently from 1Hz to 25kHz.
The Output Type setpoint determines what kind of signal the output produces. Changing this setpoint causes other setpoints in the group to update to match selected type. For this reason, the first setpoint that should be changed prior to configuring other setpoints is the Output Type setpoint. The supported output types by the controller are listed in Table 6 below:
0 Disabled 1 Proportional Current 2 Digital Hotshot 3 PWM Duty Cycle 4 Proportional Voltage (0-Vps) 5 Digital (0-Vps)
Table 6 ­ Output Type Options
There are two setpoints that are associated to Proportional Current and Digital Hotshot Output Types that are not with others – these are Dither Frequency and Dither Amplitude. The dither signal is used in Proportional Current mode and is a low frequency signal superimposed on top of the high frequency (25kHz) signal controlling the output current. The two outputs have independent dither frequencies which can be adjusted at any time. The combination of Dither Amplitude and Dither Frequency must be appropriately selected to ensure fast response to the coil to small changes in the control inputs but not so large as to affect the accuracy or stability of the output.
In Proportional Voltage type, the controller measures the Vps applied to the unit and based on this information, the controller will adjust the PWM duty cycle of the signal (0-Vps amplitude) so that the average signal is the commanded target value. Thus, the output signal is not an analog one. In order to create an analog signal, a simple low pass filter can be connected externally to the controller. Note: the output signal will saturate at Vps if the Output At Maximum Command is set higher than the supply voltage powering the controller.
In PWM Duty Cycle Output Type, the controller outputs a signal (0-Vps amplitude) on a fixed output frequency set by PWM Output Frequency with varying PWM Duty Cycle based on commanded input. Since both outputs are connected to independent timers, the PWM Output Frequency setpoint can be changed at any time for each output without affecting the other.
Digital Output Type offers the user with 4 different output responses as listed in Table 7. The controller will source any current required in any of the options listed in Table 7 up to 2.5Amps.
0 Normal On/Off 1 Inverse Logic 2 Latched Logic 3 Blinking Logic
Table 7 ­ Output Type Options

Preliminary User Manual UMAX023220. Version: 1.1

9-52

In a Normal’ response, when the Control input commands the output ON, then the output will be turned ON. However, in anInverse’ response, the output will be ON unless the input commands the output ON, in which case it turns OFF.
If a Latched’ response is selected, when the input commands the state from OFF to ON, the output will change state. If aBlinking’ response is selected, then while the input command the output ON, it will blink at the rate in the “Digital Blink Rate” setpoint. When commanded OFF, the output will stay off. A blinking response is only available with a Digital On/Off’ type of output (not a Hotshot type.) TheHotshot Digital’ type is different from `Digital On/Off’ in that it still controls the current through the load. This type of output is used to turn on a coil then reduce the current so that the valve will remain open, as shown in Figure 3. Since less energy is used to keep the output engaged, this type of response is very useful to improve overall system efficiency. With this output type there are associated three setpoints: Hold Current, Hotshot Current and Hotshot Time which are used to configure form of the output signal as shown in Figure 3.

Figure 3 ­ Hotshot Digital Profile
For Proportional outputs signal minimum and maximum values are configured with Output At Minimum Command and Output At Maximum Command setpoints. Value range for both of the setpoints is limited by selected Output Type.
Regardless of what type of control input is selected, the output will always respond in a linear fashion to changes in the input per `Equation 3′.

Equation 3 – Linear Slope Calculations
In the case of the Output Control Logic function block, X and Y are defined as Xmin = Control Input Minimum ; Ymin = Output at Minimum Command Xmax = Control Input Maximum; Ymax = Output at Maximum Command
Preliminary User Manual UMAX023220. Version: 1.1

10-52

In all cases, while X-axis has the constraint that Xmin < Xmax, there is no such limitation on the Yaxis. Thus configuring Output At Minimum Command to be greater than Output At Maximum Command allows output to follow control signal inversely.
In order to prevent abrupt changes at the output due to sudden changes in the command input, the user can choose to use the independent up or down ramps to smooth out the coil’s response. The Ramp Up and Ramp Down setpoints are in milliseconds, and the step size of the output change will be determined by taking the absolute value of the output range and dividing it by the ramp time.
The Control Source setpoint together with Control Number setpoint determine which signal is used to drive the output. For example setting Control Source to Universal Input Measured and Control Number to (1) will connect signal measured from Universal Input1 to the output in question. The input signal is scaled per input type range between 0 and 1 to form control signal. Outputs respond in a linear fashion to changes in control signal. If a non-digital signal is selected to drive digital output the command state will be 0 (OFF) at or below the “Output At Minimum Command”, 1 (ON) at or above “Output At Maximum Command” and will not change in between those points.
In addition to the Control Source setpoint, the controller offers two more options that help increase its versatility ­ Enable Source/Number/Response and Override Source/Number/Response set of setpoints.
The Enable Source setpoint together with Enable Number setpoint determine the enable signal for the output in question. The Enable Response setpoint is used to select how output will respond to the selected Enable signal. Enable Response setpoint options are listed in Table 8. If a non-digital signal is selected as Enable signal the signal is interpreted as shown in Figure 2.

0 Enable When On, Else Shutoff 1 Enable When On, Else Rampoff 2 Enable When On, Else Ramp To Max 3 Enable When On, Else Ramp To Min 4 Enable When On, Else Keep Last Value 5 Enable When Off, Else Shutoff 6 Enable When Off, Else Rampoff 7 Enable When Off, Else Ramp To Max 8 Enable When Off, Else Ramp To Min 9 Enable When Off, Else Keep Last Value
Table 8 ­ Enable Response Options

Override input allows the output drive to be configured to go to a default value in the case of the override input being engaged or disengaged, depending on the logic selected in Override Response, presented on Table 9. When active, the output will be driven to the value in Output at Override Command regardless of the value of the Control input. The Override Source and Override Number together determine the Override input signal.
0 Override When On 1 Override When Off

Preliminary User Manual UMAX023220. Version: 1.1

11-52

Table 9 ­ Override Response Options
If a fault is detected in any of the active inputs (Control/Enable/Override) the output will respond per Control Fault Response setpoint as outlined in Table 10. Fault Value is defined by Output in Fault Mode setpoint value, which is interpreted in selected output units.
0 Shutoff Output 1 Apply Fault Value 2 Hold Last Value
Table 10 ­ Fault Response Options
Besides Enable and Override signals controlling a particular output; another fault mode than can occur is that of a Power Supply. Power Supply fault can be enabled to detect over voltage or under voltage which will automatically disable ALL outputs. This setpoint is associated with the Power Supply Diag function block. Also, if the Over Temperature Diag function block is enabled, then a microprocessor over-temperature reading disables all the outputs until it has cooled back to the operating range.
Fault detection is available for current output types. A current feedback signal is measured and compared to desired output current value. Fault detection and associated setpoints are presented in section 1.13.
The outputs are inherently protected against a short to GND or Vps by hardware. In case of a dead short, the hardware will automatically disable the output drive, regardless of what the processor is commanding for the output. When this happens, the processor detects output hardware shutdown and commands off the output in question. It will continue to drive non-shorted outputs normally and periodically try to re-engage the short load, if still commanded to do so. If the fault has gone away since the last time the output was engaged while shorted, the controller will automatically resume normal operation.
In the case of an open circuit, there will be no interruption of the control for any of the outputs. The processor will continue to attempt to drive the open load.
The measured current through the load is available to be broadcasted on a CAN message if desired. It is also used as the input to the diagnostic function block for each output, and an open or shorted output can be broadcasted in a DM1 message on the CAN network

1.5. Lookup Table Function Block
Lookup Tables are used to give an output response of up to 10 slopes per Lookup Table. There are two types of Lookup Table response based on X-Axis Type: Data Response and Time Response Sections 1.5.2 through 1.5.6 will describe these two X-Axis Types in more detail. If more than 10 slopes are required, a Programmable Logic Block can be used to combine up to three tables to get 30 slopes, as is described in Section 1.7.
There are two key setpoints that will affect this function block. The first is the X-Axis Source and X-Axis Number which together define the Control Source for the function block. When it is changed, the table is automatically updated with new defaults based on the X-Axis source selected if Auto Update on Setpoint Changes in the Miscellaneous block is TRUE.

Preliminary User Manual UMAX023220. Version: 1.1

12-52

1.5.1. Auto Update on Setpoint Changes
If Auto Update on Setpoint Changes is set to TRUE, the X-Values of the Lookup Tables are updated based on the X-Axis Source and X-Axis Number (i.e. the Min or Max values of the function block are updated), the associated table will also be automatically updated with default settings, based on the new X-Axis limits. However, if Auto Update on Setpoint Changes is set to FALSE then the X-Values will not get automatically updated on a setpoint change, but the minimum and maximum allowable ranges will be adjusted which the Axiomatic Electronic Assistant may give warnings for out-of-range setpoints. For example, if Universal Input 1 is configured with Minimum Range: 0.5V (Xmin) and Maximum Range: 9.8V (Xmax) and is the X-Axis Source to Lookup Table 1 with maximum X Value of 9.8V (Xmax), if Universal Input 1 is then changed to Maximum Range: 5.5V, Lookup Table 1 will not update its X-Values however, the maximum command Xmax) will be set to 5.5V so editing the maximum X Value to something higher than 5.5V, the Axiomatic Electronic Assistant will display a warning. It is up to the user’s discretion to appropriately select the values in the Lookup Tables when Auto Update on Setpoint Changes is set to FALSE.
1.5.2. X-Axis, Input Data Response
In the case where the X-Axis Type = Data Response, the points on the X-Axis represents the data of the control source. These values must be selected within the range of the control source.
When selecting X-Axis data values, there are no constraints on the value that can be entered into any of the X-Axis points. The user should enter values in increasing order to be able to utilize the entire table. Therefore, when adjusting the X-Axis data, it is recommended that X10 is changed first, then lower indexes in descending order as to maintain the below:
Xmin <= X0 <= X1 <= X2<= X3<= X4<= X5 <= X6 <= X7 <= X8 <= X9 <= X10 <= Xmax
As stated earlier, Xmin and Xmax will be determined by the X-Axis Source that has been selected.
If some of the data points are Ignored’ as described in Section 1.5.4, they will not be used in the X-Axis calculation shown above. For example, if points X4 and higher are ignored, the formula becomes Xmin <= X0 <= X1 <= X2<= X3<= Xmax instead. 1.5.3. Y-Axis, Lookup Table Output The Y-Axis has no constraints on the data that it represents. This means that inverse, or increasing/decreasing or other responses can be easily established. In all cases, the controller looks at the entire range of the data in the Y-Axis setpoints, and selects the lowest value as the Ymin and the highest value as the Ymax. They are passed directly to other function blocks as the limits on the Lookup Table output. (i.e used as Xmin and Xmax values in linear calculations.) However, if some of the data points areIgnored’ as described in Section 1.5.4, they will not be used in the Y-Axis range determination. Only the Y-Axis values shown on the Axiomatic EA will be considered when establishing the limits of the table when it is used to drive another function block, such as a Math Function Block.

Preliminary User Manual UMAX023220. Version: 1.1

13-52

1.5.4. Default Configuration, Data Response
By default, all Lookup Tables in the ECU are disabled (X-Axis Source equals Control Not Used). Lookup Tables can be used to create the desired response profiles. If a Universal Input is used as the X-Axis, the output of the Lookup Table will be what the user enters in Y-Values setpoints.
Recall, any controlled function block which uses the Lookup Table as an input source will also apply a linearization to the data. Therefore, for a 1:1 control response, ensure that the minimum and maximum values of the output correspond to the minimum and maximum values of the table’s Y-Axis.
All tables (1 to 3) are disabled by default (no control source selected). However, should an X-Axis Source be selected, the Y-Values defaults will be in the range of 0 to 100% as described in the “Y-Axis, Lookup Table Output” section above. X-Axis minimum and maximum defaults will be set as described in the “X-Axis, Data Response” section above.
By default, the X and Y axes data is setup for an equal value between each point from the minimum to maximum in each case.
1.5.5. Point To Point Response
By default, the X and Y axes are setup for a linear response from point (0,0) to (10,10), where the output will use linearization between each point, as shown in Figure 4. To get the linearization, each “Point N ­ Response”, where N = 1 to 10, is setup for a `Ramp To’ output response.

Figure 4 ­ Lookup Table with “Ramp To” Data Response
Alternatively, the user could select a Jump To’ response for “Point N ­ Response”, where N = 1 to 10. In this case, any input value between XN-1 to XN will result in an output from the Lookup Table function block of YN. An example of a Math function block (0 to 100) used to control a default table (0 to 100) but with aJump To’ response instead of the default `Ramp To’ is shown in Figure 5.

Preliminary User Manual UMAX023220. Version: 1.1

14-52

Figure 5 ­ Lookup Table with “Jump To” Data Response
Lastly, any point except (0,0) can be selected for an `Ignore’ response. If “Point N ­ Response” is set to ignore, then all points from (XN, YN) to (X10, Y10) will also be ignored. For all data greater than XN-1, the output from the Lookup Table function block will be YN-1.
A combination of Ramp To, Jump To and Ignore responses can be used to create an application specific output profile.

1.5.6. X-Axis, Time Response

As mentioned in Section 1.5, a Lookup Table can also be used to get a custom output response where the X-Axis Type is a `Time Response.’ When this is selected, the X-Axis now represents time, in units of milliseconds, while the Y-Axis still represents the output of the function block. There is also another setpoint associated to the Lookup Table when configured to Time Response which is the Table Auto-Cycle setpoint.

In this case, the X-Axis Source is treated as a digital input. If the signal is actually an analog input, it is interpreted like a digital input per Figure 2. When the control input is ON, the output will be changed over a period of time based on the profile in the Lookup Table. There are two different scenarios on how the Lookup Table will react once the profile is finished. The first option is when Table Auto-Cycle is set to FALSE in which case, once the profile has finished (i.e. index 10, or Ignored response), the output will remain at the last output at the end of the profile until the control input turns OFF. The second option is when Table Auto-Cycle is set to TRUE in which case, once the profile has finished (i.e. index 10, or Ignored response), the Lookup Table will automatically return to the 1st response and will continually be auto-cycling for as long as the input remains in the ON state.

When the control input is OFF, the output is always at zero. When the input comes ON, the profile ALWAYS starts at position (X0, Y0) which is 0 output for 0ms.

In a time response, the interval time between each point on the X-axis can be set anywhere from 1ms to 1min. [60,000 ms]

1.6. Math Function Block

There are four mathematical function blocks that allow the user to define basic algorithms. A math function block can take up to five input signals. Each input is then scaled according to the associated limit and scaling setpoints. Inputs are converted into percentage value based on the “Function X Input Y Minimum” and “Function X Input Y Maximum” values selected. For additional control the user can also adjust the “Function X Input Y Scaler”. By default, each input has a scaling weight’ of 1.0 However, each input can be scaled from -1.0 to 1.0 as necessary before it is applied in the function. For example, in the case where the user may want to combine two inputs such that a joystick (Input 1) is the primary control of an output, but the speed can be incremented or decremented based on a potentiometer (Input 2), it may be desired that 75% of the scale is controlled by the joystick position, while the potentiometer can increase or decrease the min/max output by up to 25%. In this case, Input 1 would be scaled with 0.75, while Input 2 uses 0.25. The resulting addition will give a command from 0 to 100% based on the combined positions of both inputs. A mathematical function block includes four selectable functions, which each implements equation A operator B, where A and B are function inputs and operator is function selected with setpoint Math function X Operator. Setpoint options are presented in Error! Reference source not found.. The functions are connected together, so that result of the preceding function goes into Input A of the next function. Thus Function 1 has both Input A and Input B selectable with setpoints, where Functions 2 to 3 have only Input B selectable. Input is selected by setting “Function X Input Y Source” and Function X Input Y Number. If Function X Input B Source is set to 0Control not used’ signal goes through function unchanged.

Table 11 ­ Math Function Operators

For logic operations (6, 7, 8) scaled input greater or equal to 1 is treated as TRUE. For logic operations (0 to 8), the result of the function will always be 0 (FALSE) of 1 (TRUE). For the

Preliminary User Manual UMAX023220. Version: 1.1

arithmetic functions (9 to 15), it is recommended to scale the data such that the resulting operation will not exceed full scale (0 to 100%) and saturate the output result.
When dividing, a zero divider will always result in a 100% output value for the associated function.
Lastly the resulting mathematical calculation, presented as a percentage value, can be scaled into the appropriate physical units using the Math Output Minimum Range and Math Output Maximum Range setpoints. These values are also used as the limits when the Math Function I selected as the input source for another function block.

1.7. Programmable Logic Function Block

Figure 6 ­ Programmable Logic Function Block Preliminary User Manual UMAX023220. Version: 1.1

18-52

This function block is obviously the most complicated of them all, but very powerful. The Programmable Logic can be linked to up to three tables, any one of which would be selected only under given conditions. Any three tables can be associated with the logic, and which ones are used is fully configurable.
Should the conditions be such that a particular table (1, 2 or 3) has been selected as described in Section 1.5.2, then the output from the selected table, at any given time, will be passed directly to the Logic Output.
Therefore, up to three different responses to the same input, or three different responses to different inputs, can become the input to another function block, such as an Output X Drive. To do this, the Control Source for the reactive block would be selected to be the `Programmable Logic Function Block.’
In order to enable any one of Programmable Logic blocks, the Programmable Logic Block Enabled setpoint must be set to True. They are all disabled by default.
Logic is evaluated in the order shown in Figure 7. Only if a lower number table has not been selected will the conditions for the next table be looked at. The default table is always selected as soon as it is evaluated. It is therefore required that the default table always be the highest number in any configuration.

Preliminary User Manual UMAX023220. Version: 1.1

19-52

Figure 7 ­ Programmable Logic Flowchart

1.7.1. Conditions Evaluation

The first step in determining which table will be selected as the active table is to first evaluate the conditions associated with a given table. Each table has associated with it up to three conditions that can be evaluated.

Argument 1 is always a logical output from another function block. As always, the source is a combination of the functional block type and number, setpoints Table X, Condition Y, Argument 1 Source and Table X, Condition Y, Argument 1 Number, where both X = 1 to 3 and Y = 1 to 3.

Argument 2 on the other hand, could either be another logical output such as with Argument 1, OR a constant value set by the user. To use a constant as the second argument in the operation, set Table X, Condition Y, Argument 2 Source to Control Constant Data. Note that the constant

Preliminary User Manual UMAX023220. Version: 1.1

20-52

value has no unit associated with it in the Axiomatic EA, so the user must set it as needed for the application.

The condition is evaluated based on the Table X, Condition Y Operator selected by the user. It is always =, Equa’ by default. The only way to change this is to have two valid arguments selected for any given condition. Options for the operator are listed in Table 12.

0 =, Equal 1 !=, Not Equal 2 >, Greater Than 3 >=, Greater Than or Equal 4 <, Less Than 5 <=, Less Than or Equal
Table 12 ­ Condition Operator Options

By default, both arguments are set to `Control Source Not Used’ which disables the condition, and automatically results in a value of N/A as the result. Although Figure 7 shows only True or False as a result of a condition evaluation, the reality is that there could be four possible results, as described in Table 13.

Value 0 1 2 3

Meaning False True Error Not Applicable

Reason (Argument 1) Operator (Argument 2) = False (Argument 1) Operator (Argument 2) = True Argument 1 or 2 output was reported as being in an error state Argument 1 or 2 is not available (i.e. set to `Control Source Not Used’)
Table 13 ­ Condition Evaluation Results

1.7.2. Table Selection

In order to determine if a particular table will be selected, logical operations are performed on the results of the conditions as determined by the logic in Section 1.7.1. There are several logical combinations that can be selected, as listed in Table 14.

0 Default Table 1 Cnd1 And Cnd2 And Cnd3 2 Cnd1 Or Cnd2 Or Cnd3 3 (Cnd1 And Cnd2) Or Cnd3 4 (Cnd1 Or Cnd2) And Cnd3
Table 14 ­ Conditions Logical Operator Options

Not every evaluation is going to need all three conditions. The case given in the earlier section, for example, only has one condition listed, i.e. that the Engine RPM be below a certain value. Therefore, it is important to understand how the logical operators would evaluate an Error or N/A result for a condition.

Logical Operator Default Table Cnd1 And Cnd2 And Cnd3

Select Conditions Criteria Associated table is automatically selected as soon as it is evaluated. Should be used when two or three conditions are relevant, and all must be true to select the table.

If any condition equals False or Error, the table is not selected. An N/A is treated like a True.

Preliminary User Manual UMAX023220. Version: 1.1

21-52

If all three conditions are True (or N/A), the table is selected.

Cnd1 Or Cnd2 Or Cnd3

If((Cnd1==True) &&(Cnd2==True)&&(Cnd3==True)) Then Use Table Should be used when only one condition is relevant. Can also be used with two or three relevant conditions.

If any condition is evaluated as True, the table is selected. Error or N/A results are treated as False

If((Cnd1==True) || (Cnd2==True) || (Cnd3==True)) Then Use Table (Cnd1 And Cnd2) Or Cnd3 To be used only when all three conditions are relevant.

If both Condition 1 and Condition 2 are True, OR Condition 3 is True, the table is selected. Error or N/A results are treated as False

If( ((Cnd1==True)&&(Cnd2==True)) || (Cnd3==True) ) Then Use Table (Cnd1 Or Cnd2) And Cnd3 To be used only when all three conditions are relevant.

If Condition 1 And Condition 3 are True, OR Condition 2 And Condition 3 are True, the table is selected. Error or N/A results are treated as False

If( ((Cnd1==True)||(Cnd2==True)) && (Cnd3==True) ) Then Use Table
Table 15 ­ Conditions Evaluation Based on Selected Logical Operator

The default Table X, Conditions Logical Operator for Table 1 and Table 2 is Cnd1 And Cnd2 And Cnd3, while Table 3 is set to be the Default Table.

1.7.3. Logic Block Output
Recall that Table X, where X = 1 to 3 in the Programmable Logic function block does NOT mean Lookup Table 1 to 3. Each table has a setpoint Table X ­ Lookup Table Block Number which allows the user to select which Lookup Tables they want associated with a particular Programmable Logic Block. The default tables associated with each logic block are listed in Table 8.

Table 16 ­ Programmable Logic Block Default Lookup Tables

If the associated Lookup Table does not have an X-Axis Source selected, then the output of the Programmable Logic block will always be “Not Available” so long as that table is selected. However, should the Lookup Table be configured for a valid response to an input, be it Data or Time, the output of the Lookup Table function block (i.e. the Y-Axis data that has been selected based on the X-Axis value) will become the output of the Programmable Logic function block so long as that table is selected.

Unlike all other function blocks, the Programmable Logic does NOT perform any linearization calculations between the input and the output data. Instead, it mirrors exactly the input (Lookup Table) data. Therefore, when using the Programmable Logic as a control source for another

Preliminary User Manual UMAX023220. Version: 1.1

22-52

function block, it is HIGHLY recommended that all the associated Lookup Table Y-Axes either be (a) Set between the 0 to 100% output range or (b) all set to the same scale.

1.8. PID Control Function Block

The PID Control function block is an independent logic block, but it is normally intended to be associated with proportional output control blocks described earlier. When the Control Source for an output has been setup as a `PID Function Block’, the command from the selected PID block drives the physical output on the High Temperature 2 Input 2 Output Valve Controller. The PID Target Command Source and PID Target Command Number setpoints determine control input and the PID Feedback Input Source and PID Feedback Input Number setpoints determine the established the feedback signal to the PID function block. The PID Response Profile will use the selected inputs as per the options listed in Table 3. When active, the PID algorithm will be called every PID Loop Update Rate in milliseconds.

0 Single Output 1 Setpoint Control 2 On When Over Target 3 On When Below Target
Table 2 ­ PID Response Options

When a `Single Output’ response is selected, the Target and Feedback inputs do not have to share the same units. In both cases, the signals are converted to a percentage values based on the minimum and maximum values associated with the source function block.

For example, a CAN command could be used to set the target value, in which case it would be converted to a percentage value using Receive Data Min and Receive Data Max setpoints in the appropriate CAN Receive X function block. The closed-loop feedback signal (i.e. a 0-5V input) could be connected to `Universal Input 1′ and selected as the feedback source. In this case the value of the input would be converted to a percentage based on the Minimum Range and Maximum Range setpoints in the input block. The output of the PID function would depend on the difference between the commanded target and the measured feedback as a percentage of each signals range. In this mode, the output of the block would be a value from -100% to 100%.

When a Setpoint Control response is selected, the PID Target Command Source automatically gets updated to Control Constant Data and cannot be changed. The value set in the associated constant in the Constant Data List function block becomes the desired target value. In this case, both the target and the feedback values are assumed to be in same units and range. The minimum and maximum values for the feedback automatically become the constraints on the constant target. In this mode, the output of the block would be a value from 0% to 100%.

For example, if the feedback was setup as a 4-20mA input, a Constant Value X setpoint set to 14.2 would automatically be converted to 63.75%. The PID function would adjust the output as needs to have the measured feedback to maintain that target value.

The last two response options, On When Over Target’ andOn When Under Target’, are designed to allow the user to combine the two proportional outputs as a push-pull drive for a system. Both outputs must be setup to use the same control input (linear response) and feedback signal in order to get the expected output response. In this mode, the output would be between 0% to 100%.

Preliminary User Manual UMAX023220. Version: 1.1

23-52

In Order to allow the output to stabilize, the user can select a non-zero value for PID Delta Tolerance. If the absolute value of ErrorK is less than this value, ErrorK in the formula below will be set to zero.
The PID algorithm used is shown below, where G, Ki, Ti, Kd, Td and Loop_UpdateRate are configurable parameters.

= = = ( – -1)
= – = -1 +
= = / (Note: If Ti is zero, IGain = 0) = /

Equation 4 – PID Control Algorithm
Each system will have to be turned for the optimum output response. Response times, overshoots and other variables will have to be decided by the customer using an appropriate PID tuning strategy. Axiomatic is not responsible for tuning the control system.

1.9. Set / Reset Function Block

Set-Reset Block consists of only 2 control sources: Reset Source and Set Source. The purpose of these blocks is to simulate a modified latching function in which the Reset Signal’ has more precedence. Thelatching’ function works as per the Table 18 below.

Table 18 ­ Set-Rest Function block operation

If either Reset Source or Set Source is a non-digital signal, the signal is interpreted as OFF if the signal is at or below the minimum of the selected source; and is interpreted as ON at or above the maximum of the selected source. The ON/OFF states of the signal will not change in between. Thus analog to digital interpretation has a built-in hysteresis defined by the signal’s minimum and maximum ranges, as shown in Figure 3.

Preliminary User Manual UMAX023220. Version: 1.1

24-52

An example of the explanation above: if Universal Input 1 is configured as a 0-5V input with Minimum Range: 0.5V and Maximum Range: 3.5V and is used in this block as Set Source. If the measured input signal is 0.5V, the Set Signal’ will be OFF and will remain OFF until the measured input signal has reached 3.5V or higher (but less than Maximum Error) in which caseSet Signal’ will switch to ON. At this point, the state of Set Signal’ will remain ON until the measured input signal has reached 0.5V (but higher than Minimum Error) in which case the state ofSet Signal’ will switch OFF.
As seen in Table 18 above, the Reset Signal’ has more precedence over the Set Signal’ – as long as the state of Reset Signal’ is ON, the state of Set-Reset Block Output’ will be OFF. In order to create an ON state in Set- Reset Block Output’ the state ofReset Signal’ must be OFF while the state of Set Signal’ is ON. In this case, the state ofSet-Reset Block Output’ will remain ON even if Set Signal’ turns OFF as long asReset Signal’ remains OFF. As soon as the Reset Signal’ turns ON theSet-Reset Block Output’ will turn OFF regardless of the state of `Set Signal’.

1.10. Diagnostic Trouble Code (DTC) React
The DTC React function block will allow a received DTC sent from another ECU on a DM1 message to be used as an input to any other function block in order to disable an output, for example. Up to three SPN/FMI combinations can be selected.
Should a DM1 message be received with the SPN/FMI combination defined, the corresponding DTC State will be set to ON. Once ON, if the same SPN/FMI combination has not been received again after 3 seconds, the DTC State will be reset to OFF.
The DTC could be used as a digital input for any function block as appropriate.

1.11. CAN Transmit Message Function Block

The CAN Transmit function block is used to send any output from another function block (i.e. Universal Input, CAN Received) to the J1939 network. The AX023220 ECU has five CAN Transmit Messages with each having one user-defined signal.

1.11.1. CAN Transmit Message Setpoints

The Transmit PGN setpoint sets PGN used with the message. User should be familiar with the SAE J1939 standard, and select values for PGN/SPN combinations as appropriate from section J1939/71.

Repetition Rate setpoint defines the interval used to send the message to the J1939 network. If the Repetition Rate is set to zero, the message is disabled unless it shares its PGN with another message. In case of a shared PGN repetition rate of the LOWEST numbered message are used to send the message `bundle’.
By default, all messages are sent on Proprietary B PGNs as broadcast messages. Thus Transmit Message Priority is always initialized to 6 (low priority) and the Destination Address setpoint is not used. This setpoint is only valid when a PDU1 PGN has been selected, and it can be set either to the Global Address (0xFF) for broadcasts, or sent to a specific address as setup by the user.

Preliminary User Manual UMAX023220. Version: 1.1

25-52

1.11.2. CAN Transmit Signal Setpoints
Each CAN transmit message has one associated signal, which define data inside the Transmit message. Control Source setpoint together with Control Number setpoint define the signal source of the message. Control Source and Control Number options are listed in Error! Reference source not found. and Table 5. Setting Control Source to Control Not Used disables the signal.
Transmit Data Size setpoint determines how many bits signal reserves from the message. Transmit Data Index in Array determines in which of 8 bytes of the CAN message LSB of the signal is located. Similarly Transmit Bit Index in Byte determines in which of 8 bits of a byte the LSB is located. These setpoints are freely configurable, thus it is the user’s responsibility to ensure that signals do not overlap and mask each other.
Transmit Data Resolution setpoint determines the scaling done on the signal data before it is sent to the bus. Transmit Data Offset setpoint determines the value that is subtracted from the signal data before it is scaled. Offset and Resolution are interpreted in units of the selected source signal.
1.12. CAN Receive Function Block
The CAN Receive function block is designed to take any SPN from the J1939 network, and use it as an input to another function block.
The Receive Message Enabled is the most important setpoint associated with this function block and it should be selected first. Changing it will result in other setpoints being enabled/disabled as appropriate. By default ALL receive messages are disabled.
Once a message has been enabled, a Lost Communication fault will be flagged if that message is not received within the Receive Message Timeout period. This could trigger a Lost Communication event as described in section 1.13. In order to avoid timeouts on a heavily saturated network, it is recommended to set the period at least three times longer than the expected update rate. To disable the timeout feature, simply set this value to zero, in which case the received message will never trigger a Lost Communication fault.
By default, all control messages are expected to be sent to the High Temperature 2 Input 2 Output Valve Controller on Proprietary B PGNs. However, should a PDU1 message be selected, the High Temperature 2 Input 2 Output Valve Controller can be setup to receive it from any ECU by setting the Specific Address that sends the PGN to the Global Address (0xFF). If a specific address is selected instead, then any other ECU data on the PGN will be ignored.
The Receive Data Size, Receive Data Index in Array (LSB), Receive Bit Index in Byte (LSB), Receive Resolution and Receive Offset can all be used to map any SPN supported by the J1939 standard to the output data of the Received function block.
As mentioned earlier, a CAN receive function clock can be selected as the source of the control input for the output function blocks. When this is the case, the Received Data Min (Off Threshold) and Received Data Max (On Threshold) setpoints determine the minimum and maximum values of the control signal. As the names imply, they are also used as the On/Off thresholds for digital

Preliminary User Manual UMAX023220. Version: 1.1

26-52

output types. These values are in whatever units the data is AFTER the resolution and offset is applied to CAN receive signal.
The High Temperature 2 Input 2 Output Valve Controller I/O supports up to five unique CAN Receive Messages.

1.13. Diagnostic Function Blocks

The High Temperature 2 Input 2 Output Valve Controller supports diagnostic messaging. DM1 message is a message, containing Active Diagnostic Trouble Codes (DTC) that is sent to the J1939 network in case a fault has been detected. A Diagnostic Trouble Code is defined by the J1939 standard as a four byte value.

In addition to supporting the DM1 message, the following are supported:

DM2 Previously Active Diagnostic Trouble Codes

Sent only on request

SPN Suspect Parameter Number (user defined)

FMI Failure Mode Identifier

(see Table and Table )

CM Conversion Method

(always set to 0)

OC Occurrence Count

(number of times the fault has happened)

DM3 Diagnostic Data Clear/Reset of Previously Active DTCs Done only on request

DM11 Diagnostic Data Clear/Reset for Active DTCs

Fault detection and reaction is associated with the two Universal Inputs and with the two Proportional Outputs. However not all the input and output types support fault diagnostics. Fault diagnostics are not available for digital input types, and thus diagnostic setpoints are not used with them. The Proportional Outputs are associated with current feedback, which is utilized with Proportional Current’ andDigital Hotshot’ output types. For other output types, the output fault detection/reaction setpoints are ignored. In addition to input/output faults, the High Temperature 2 Input 2 Output Valve Controller can also detect/react to three additional faults namely power supply fault, over temperature fault and communication fault.

The Axiomatic EA provides several setpoints to configure diagnostics. Input and output error diagnostic setpoints are among the setpoint group of each input/output and diagnostic setpoints for additional faults are presented as their own setpoint groups in the Axiomatic EA.

Fault detection thresholds are presented in Table 4. Input errors can be flagged as either a high or low occurrence, thus there are two user selectable threshold value setpoints Maximum error and Minimum error. Input error thresholds are interpreted in Input Sensor Type units. Changing input type will change Minimum error and Maximum error to corresponding default values, thus Input Sensor Type should be set before adjusting Minimum error and Maximum error setpoints. Fault detection can be performed only if the thresholds are within the range of permitted values which are listed in Table

1. For example 0 to 5 voltage input maximum error has to be less than 5V to enable detection of the fault high occurrence.

Power Supply fault can be also flagged as either a high or low occurrence and has two selectable threshold setpoints. Over Temperature fault reacts only to a single condition and thus, the only one threshold setpoint is supplied. Lost Communication fault occurs if no CAN messages are received

Preliminary User Manual UMAX023220. Version: 1.1

27-52

within Receive Message Timeout time. The proportional output can be selected to disable in a case of a power supply and/or temperature error, by setting Power Fault Disables Outputs and/or Over Temperature Shutdown setpoint value to `True’.

A proportional output fault is monitored from measured current feedback and is thus applicable only on current output types (i.e. Proportional Current and Digital Hotshot). Measured current feedback value is compared with desired current value and if the difference between the two is greater than Hysteresis to Clear Fault setpoint value, an open circuit will be flagged. A hardware shutdown will occur if the output is sourcing greater than 2.5A +/- 0.5A, most likely due to a short circuit on the load. Output diagnostics are not available for non-current output types.

A hysteresis can be applied to prevent rapid setting and clearing of the error flag when signal value is near the fault detection threshold. Input error and additional error detection hysteresis is configured with Hysteresis to clear fault setpoint.

Generate Diagnostic Messages setpoint determines whether an active fault generates diagnostic trouble code (DTC) that is sent to J1939 network as part of diagnostic message (DM). So long as even one Diagnostic function block has Generate Diagnostic Messages set to True, the High Temperature 2 Input 2 Output Valve Controller will send the DM1 message every one second, regardless of whether or not there are any active faults, as recommended by standard. While there are no active DTCs, the High Temperature 2 Input 2 Output Valve Controller will send “No Active Faults” message. If a previously inactive DTC becomes active, a DM1 will be sent immediately to reflect this. As soon as the last active DTC goes inactive, a DM1 indicating that there are no more active DTCs will be sent.

If there is more than one active DTC at any given time, the regular DM1 message will be sent using a multipacket message to the Requester Address using the Transport Protocol (TP).

When the fault is linked to a DTC, a non-volatile log of the occurrence count (OC) is kept. As soon as the controller detects a new (previously inactive) fault, it will start decrementing the Delay Before Sending DM1 timer for that Diagnostic function block. If the fault has remained present during the delay time, then the controller will set the DTC to active, and will increment the OC in the log. A DM1 will immediately be generated that includes the new DTC. The timer is provided so that intermittent faults do not overwhelm the network as the fault comes and goes, since a DM1 message would be sent every time the fault shows up or goes away.

By default, the fault flag is cleared when error condition that has caused it goes away. The DTC is made Previously Active and is it is no longer included in the DM1 message. To identify a fault having happened, even if the condition that has caused is one away, the Event Cleared only by DM11 setpoint can be set to True. This configuration enables DTC to stay Active, even after the fault flag has been cleared, and be included in DM1 message until a Diagnostic Data Clear/Reset for Active DTCs (DM11) has been requested.

Preliminary User Manual UMAX023220. Version: 1.1

28-52

As defined by J1939 Standard the first byte of the DM1 message reflects the Lamp status. “Lamp Set by Event in DM1” setpoint determines the lamp type set in this byte of DTC. “Lamp Set by Event in DM1” setpoint options are listed in Table 20. By default, the `Amber, Warning’ lamp is typically the one set be any active fault.

0 Protect 1 Amber Warning 2 Red Stop 3 Malfunction
Table 20 ­ Lamp Set by Event in DM1 Options

SPN for Event used in DTC defines suspect parameter number used as part of DTC. The default value zero is not allowed by the standard, thus no DM will be sent unless SPN for Event used in DTC in is configured to be different from zero. It is user’s responsibility to select SPN that will not violate J1939 standard. When the SPN for Event used in DTC is changed, the OC of the associated error log is automatically reset to zero.

When FMI is selected from Low Fault FMIs in Table for a fault that can be flagged either high or low occurrence, the high occurrence automatically uses corresponding High Fault FMI by Table 22. If any other FMI is selected than the Low Fault FMI from the table ref, then both the low and high fault will be assigned the same FMI.

2.2. Mounting Instructions
NOTES & WARNINGS · Do not install near high-voltage or high-current devices. · Note the operating temperature range. All field wiring must be suitable for that temperature range. · Install the unit with appropriate space available for servicing and for adequate wire harness access (15
cm) and strain relief (30 cm). · Do not connect or disconnect the unit while the circuit is live, unless the area is known to be non-
hazardous.

MOUNTING
The module is designed for mounting on the valve block. If it is mounted without an enclosure, the controller should be mounted horizontally with connectors facing left or right, or with the connectors facing down, to reduce likelihood of moisture entry.
Mask all labels if the unit is to be repainted, so label information remains visible.
Mounting legs include holes sized for ¼” bolts. The bolt length will be determined by the end-user’s mounting plate thickness. Typically 20 mm (3/4 inch) is adequate.

If the module is mounted away from the valve block, no wire or cable in the harness should exceed 30 meters in length. The power input wiring should be limited to 10 meters.

CONNECTIONS

Use the following TE Deutsch mating plugs to connect to the integral receptacles. Wiring to these mating plugs must be in accordance with all applicable local codes. Suitable field wiring for the rated voltage and current must be used. The rating of the connecting cables must be at least 85°C. For ambient temperatures below ­10°C and above +70°C, use field wiring suitable for both minimum and maximum ambient temperature.

Refer to the respective TE Deutsch datasheets for usable insulation diameter ranges and other instructions.

None of the application layer PGNs are supported as part of the default configurations, but they can be selected as desired for either transmit or received function blocks. Setpoints are accessed using standard Memory Access Protocol (MAP) with proprietary addresses. The Axiomatic Electronic Assistant (EA) allows for quick and easy configuration of the unit over the CAN network.

3.2. NAME, Address and Software ID

J1939 NAME The High Temperature 2 Input 2 Output Valve controller ECU has the following defaults for the J1939 NAME. The user should refer to the SAE J1939/81 standard for more information on these parameters and their ranges.

Arbitrary Address Capable Industry Group Vehicle System Instance Vehicle System Function Function Instance ECU Instance Manufacture Code Identity Number

Yes 0, Global 0 0, Non-specific system 125, I/O Controller (Axiomatic- specific) 10, Axiomatic AX023200, 2 Input 2 Output High Temperature Controller 0, First Instance 162, Axiomatic Technologies Corporation Variable, uniquely assigned during factory programming for each ECU

The ECU Instance is a configurable setpoint associated with the NAME. Changing this value will allow multiple ECUs of this type to be distinguishable by other ECUs (including the Axiomatic Electronic Assistant) when they are all connected on the same network.

ECU Address The default value of this setpoint is 128 (0x80), which is the preferred starting address for selfconfigurable ECUs as set by the SAE in J1939 tables B3 to B7. The Axiomatic EA supports the selection of any address between 0 to 253, and it is the user’s responsibility to select an address that complies with the standard. The user must also be aware that since the unit is arbitrary address capable, if another ECU with a higher priority NAME contends for the selected address, the High Temperature 2 Input 2 Output Valve controller will continue select the next highest address until it find one that it can claim. See J1939/81 for more details about address claiming.

ECU SETPOINTS ACCESSED WITH THE AXIOMATIC ELECTRONIC ASSISTANT

Many setpoints have been reference throughout this manual. This section describes in detail each setpoint, and their defaults and ranges. For more information on how each setpoint is used by the High Temperature 2 Input 2

Output, refer to the relevant section of the User Manual.
4.1. J1939 Network Setpoints

Name ECU Address ECU Instance Number

Range 0 to 253 Drop List

Default
128 (0x80)
0, #1 ­ First Instance

Notes Preferred address for a selfconfigurable ECU
Per J1939-81

If non-default values for the “ECU Instance Number” or “ECU Address” are used, they will not be updated during a setpoint file flash. These parameters need to be changed manually in order to prevent other units on the network to be affected. When they are changed, the controller will claim its new address on the network. It is recommended to close and re-open the CAN connection on the Axiomatic EA after the file is loaded, such that only the new NAME and address appear in the J1939 CAN Network ECU list.

4.2. Miscellaneous Setpoints
The Miscellaneous setpoints primarily deal setpoints which apply to the overall controller and/or a set of setpoint groups. Refer to the notes for more information about each setpoint.

REFLASHING OVER CAN WITH THE AXIOMATIC EA BOOTLOADER

The AX023220 can be upgraded with new application firmware using the Bootloader Information section. This section details the simple step-by-step instructions to upload new firmware provided by Axiomatic onto the unit via CAN, without requiring it to be disconnected from the J1939 network.
1. When the Axiomatic EA first connects to the ECU, the Bootloader Information section will display the following information.

2. To use the bootloader to upgrade the firmware running on the ECU, change the variable “Force Bootloader To Load on Reset” to Yes.

3. When the prompt box asks if you want to reset the ECU, select Yes.
Preliminary User Manual UMAX023220. Version: 1.1

44-52

4. Upon reset, the ECU will no longer show up on the J1939 network as an AX023220 but rather as J1939 Bootloader #1.

Note that the bootloader is NOT Arbitrary Address Capable. This means that if you want to have multiple bootloaders running simultaneously (not recommended) you would have to manually change the address for each one before activating the next, or there will be address conflicts, and

Preliminary User Manual UMAX023220. Version: 1.1

45-52

only one ECU would show up as the bootloader. Once the `active’ bootloader returns to regular functionality, the other ECU(s) would have to be power cycled to re-activate the bootloader feature.
5. When the Bootloader Information section is selected, the same information is shown as when it was running the AX023220 firmware, but in this case the Flashing feature has been enabled.

6. Select the Flashing button and navigate to where you had saved the AF-15111-x.yy.bin file sent from Axiomatic. (Note: only binary (.bin) files can be flashed using the Axiomatic EA tool)

Preliminary User Manual UMAX023220. Version: 1.1

46-52

7. Once the Flash Application Firmware window opens, you can enter comments such as “Firmware upgraded by [Name]” if you so desire. This is not required, and you can leave the field blank if you do not want to use it.
Note: You do not have to date-stamp or timestamp the file, as this is done automatically by the Axiomatic EA tool when you upload the new firmware.

WARNING: Do not check the “Erase All ECU Flash Memory” box unless instructed to do so by your Axiomatic contact. Selecting this will erased ALL data stored in nonvolatile flash. It will also erase any configuration of the setpoints that might have been done to the ECU and reset all setpoints to their factory defaults. By leaving this box unchecked, none of the setpoints will be changed when the new firmware is uploaded.
8. A progress bar will show how much of the firmware has been sent as the upload progresses. The more traffic there is on the J1939 network, the longer the upload process will take.

Preliminary User Manual UMAX023220. Version: 1.1

47-52

9. Once the firmware has finished uploading, a message will popup indicating the successful operation. If you select to reset the ECU, the new version of the AX023220 application will start running, and the ECU will be identified as such by the Axiomatic EA. Otherwise, the next time the ECU is power-cycled, the AX023220 application will run rather than the bootloader function.
Note: If at any time during the upload the process is interrupted, the data is corrupted (bad checksum) or for any other reason the new firmware is not correct, i.e. bootloader detects that the file loaded was not designed to run on the hardware platform, the bad or corrupted application will not run. Rather, when the ECU is reset or power-cycled the J1939 Bootloader will continue to be the default application until valid firmware has been successfully uploaded into the unit.
