Programming the DIO-16.LPCI

Sealevel’s SeaI/O software is provided to assist in the development of reliable applications for the Sealevel Systems family of digital I/O adapters. Included in the software are driver functions for use in accessing the I/O as well as helpful samples and utilities.

Programming for Windows
The SeaI/O API (Application Programmer Interface) provides a variety of useful high-level function calls implemented in a Windows dynamic link library (DLL). The API is defined in the help file (Start/Programs/SeaIO/SeaIO Help) under “Application Programmers Interface.” This help file also includes detailed information dealing with installation / removal of the software and information about latency, logic states, and device configuration. For C language programmers we recommend using the API to access the DIO-16.LPCI. If you are programming in Visual Basic, using the ActiveX control included with SeaI/O is advised.

Samples and Utilities
A variety of sample programs and utilities (both executable and source code) are included with SeaI/O. Further documentation on these samples can be found by selecting “Start/Programs/SeaIO/Sample Application Description.” Information about where the files are physically stored on your disk is also included in this same file.

Programming for Linux
SeaI/O for Linux consists of two major parts: a kernel module and a library. The kernel module is a simple IO pass-through device, allowing the library to handle the more sophisticated functions provided to SeaI/O users. It is provided in a `tarball’ format and can easily be compiled and included in the kernel build.

Direct Hardware Control
In systems where the user’s program has direct access to the hardware (DOS) the tables that follow give the mapping and functions that the DIO-16.LPCI provides. The DIO-16.LPCI provides two parallel input/output (I/O) ports. The ports are organized as ports A and C. Port A is an input port interfaced to optically-isolated inputs, while port C is the reed relay output port.

Register Layout

Reference the following sections for more information about the meaning and use of the registers available.

Address| Mode| Mode| D7| D6| D5| D4| D3| D2| D1| D0
---|---|---|---|---|---|---|---|---|---|---
Base+0| Input Port A| RD| PAD7| PAD6| PAD5| PAD4| PAD3| PAD2| PAD1| PAD0
Base+2| Output Port C| RD/WR| PCD7| PCD6| PCD5| PCD4| PCD3| PCD2| PCD1| PCD0
Base+5| Interrupt Status| RD/WR| IRQEN| IRQST| 0| 0| 0| 0| IRC1| IRC0

Reading the Inputs
The inputs are active Low. If no voltage is applied across one of the differential inputs it returns a one on that bit. If an AC or DC voltage is applied it returns a zero on that bit.

Reading the Outputs
The relay ports return the ones complement of the value that is currently being used to drive the relays. When using the API, the actual value is returned not the complement of the value.

Writing the Outputs
The output ports are the only ports that can be written. The relays on a standard DIO-16.LPCI are normally open. To close a relay a one must be written to the appropriate bit.
Interrupt Control
When enabled, interrupts are generated on Port A bit D0.

IRQEN| Interrupt enable| 1 = enabled| 0 = disabled ( 0 on power up )
---|---|---|---
IRC0

IRC1

| Interrupt mode select, see table below

Interrupt mode select, see table below

Interrupt Mode Select Table
Interrupt source is Base+5 bits D1 and D0. When selecting the Interrupt Type, always disable interrupts prior to changing or setting states. This will help prevent inadvertent or unexpected interrupts from occurring.

When using the High and Low Level interrupts, an interrupt occurs when input D0 changes to either a High or Low state. This will cause the computer to remain in an interrupt state until the input state changes.

Interrupt Read
Reading the Interrupt Status port (Base+5) clears any interrupt pending.

Input Ports
Port A is an 8 bit input port connected to optically isolated input sensors. Each sensor can be used to interface a voltage input and then sense whether the voltage is on or off. Each sensor is isolated (with respect to a common ground) from every other sensor and is also isolated with respect to the host PC ground. This means that signals such as low-level AC line voltage, motor servo voltage, and control relay signals can be sensed,’ or read by the PC, without the risk of damage due to ground loops or ground faults. Each sensor input pair has a current limiting resistor that is used to limit the input current to the opt isolator. The opto-isolator has twoback-to- back’ diodes internally. This allows AC or DC signals to be sensed, regardless of polarity. When the applied voltage is high enough to cause the LED in the opto-isolator to turn-on, the output of the opto-isolator goes low (0 volts), and the signal is read as a low logic level (binary 0) by the PC. When the input signal is too low to turn on the opto-isolator, the output goes high, and the port bit is read by the PC as a high logic level (binary 1).
The input impedance of each isolated input is approximately 560 ohms (factory default). The opto-isolator requires approximately 3mA to turn on. The maximum input current is 20mA.

The input circuits are not intended for monitoring 120-volt AC circuits. In addition to being too high a voltage for the circuits, it is dangerous to have that high a voltage on the card.

Input Port Pin Assignments (DB-44 Female)

The above diagram is representative of how dry contact inputs (or current / voltage sources) can be monitored by the optically isolated inputs. When switch 1 above is closed, it will allow current to flow from the power source, into pin 3 of the DB-44, through the optocoupler, out pin 41, and back to the power source. If the current flow is between 3 and 20 milliamps, this input will be read as logic “0”. All the input associated with all open switches will be read as logic “1”. In the diagram above, pins 36-38, and 40-44 are joined, providing a common return path for the optocouplers. In this case, the interconnections are being made on the connector itself. In the DB-37 diagram below the return path is supplied external to the connector. Also, for complete electrical isolation, each input / output pair can be powered from an individual power source with no common present.

Output Ports (Reed Relay)
Reed relays provide very high quality, long life, low current (10 Watt maximum), dry contact switch closures. Reed relays are not suited for high current applications, and can be destroyed by inductive load switching, where a spark occurs across the contacts internally. The relays are normally open, and close when energized.

Output Ports (Reed Relay) Pin Assignments (DB-44 Female)

The above diagram is representative of how lights (or other devices) can be controlled by the relay outputs. When relay 2 on the card is closed, it will allow current to flow from the power source, into pin 12 of the DB44, through the relay, out pin 30, and back to the power source thereby turning the light labeled “2” on. In the diagram above, pins 28-30 and 31-35 of the connector are joined, providing a common return path for the circuit. In this case the interconnections are being made on the connector itself. In the DB-37 diagram below the return path is supplied external to the connector. For complete electrical isolation, each relay can be wired to an independent isolated circuit.

Power and Ground Pin Assignments (DB-44 Female)

DB-37 Male Pin Assignment
Via optional DB-44 Male to DB-37 Male 6′ cable, Part Number CA206

The diagram is representative of how dry contact inputs (or current / voltage sources) can be monitored by the optically isolated inputs. When switch 1 above is closed, it will allow current to flow from the power source, into pin 3 of the DB-37, through the optocoupler, out pin 21, and back to the power source. If the current flow is between 3 and 50 milliamps, this input will be read as logic “0”. All the input associated with all open switches will be read as logic “1”. The above diagram shows that the common path to the optocouplers is provided external to the connector. The common path can be provided at the connector as shown in the DB-44 diagram above. Also, for complete electrical isolation, each input / output pair can be powered from an individual power source with no common present.

The diagram above diagram is representative of how lights (or other devices) can be controlled by the relay outputs. When relay 2 on the card is closed, it will allow current to flow from the power source, into pin 12 of the DB-37, through the optocoupler, out pin 30, and back to the power source thereby turning the light labeled “2” on. The above diagram shows the common path to all the relays is provided external to the connector. The common path can be provided at the connector as shown in the DB-44 diagram above. For complete electrical isolation, each relay can be wired to an independent isolated circuit.

Verification Utilities For SeaIO Classic Products

These three utilities were designed to verify the functionality of your Sealevel digital I/O adapters. To access these utilities, navigate to: Start ­ All Programs ­ SeaIO.

VB Test
This utility allows the setting and clearing of individual relays and groups of relays. It also offers timed activation of relays and monitoring of input signals.

VCTEST
This utility allows the setting and clearing of individual relays. It also offers monitoring of input signals.

SeaIOTST
This utility is a Win32 console application designed for testing all calls to the driver. This utility is very useful for verifying proper SeaIO driver configuration and hardware adapter settings. A main menu offers choices for reading and writing ports and setting and clearing relays. This utility also demonstrates the use of the NotifyInputChange API call.

SeaI/O Classic Hardware
This is an example of a properly enumerated SeaI/O digital I/O adapter in Windows Device Manager.
Right click on the adapter line item under the SeaI/O Device category and choose `Properties.’ This will show the Properties dialog box, as seen below.

This verifies that the SeaI/O digital I/O adapter (8004) is correctly enumerated.
To properly configure your digital, I/O adapter, please click on the `Card Setup’ tab and refer to the Configuration section of this manual.

SeaIO Device Driver Configuration

Configure your SeaI/O adapter device driver settings by navigating to

the Device Manger and opening the Properties dialog box for the installed SeaI/O adapter device. Choose the Card Setup tab. The example below shows a SeaI/O 8004 adapter.
Card Selection Configuration

Sample Interval
This parameter sets the time interval for the timer used by the device driver to check the adapter for input state changes. To use, your application must invoke the SeaIO_NotifyInputChange overlapped API device driver call. The default value on installation is 250,000 microseconds (250 milliseconds).

Setting the sampling rate below 10,000 microseconds is not recommend as this can heavily tax the host processor. When the Sample Interval parameter is non- zero, the driver to periodically look at the inputs to see when one changes. When an input changes, the driver will complete the previously issued overlapped call. The driver utilizes a recurring timer to notify it to look at the inputs. The period of time (in microseconds) that occurs between passes of the driver looking at the inputs is specified in the Sample Interval box.

Additional information on Sample Interval can be located in the SeaIO Software Information Help file found here: Start ­ All Programs ­ SeaIO ­ SeaIO Help – Device Configuration.

Logic States
The combo box allows selection of the type of logic that the driver will use: Positive or Negative. The default selection is Positive logic.

The original SeaIO API treated devices as if they had active low inputs. This behavior has been revised. The current SeaIO API returns inputs as active high.

Legacy SeaIO calls are: SeaIO_ReadReg and SeaIO_WriteReg functions. Their counterparts are: SeaIO_ReadByte, SeaIO_WriteByte, SeaIO_ReadBit, SeaIO_WriteBit, SeaIO_WriteAllOutputs and SeaIO_ReadAllInputs. These functions should be used exclusively by new applications.
