2.4.1. ANALOG INPUT UPDATE TIME
Sampling time can be configured from 4ms to 400ms per each channel.
By activating 8 channels and setting a sampling time of 4 ms, you get an input update every: 4*8 = 32 ms.
Note (only if thermocouple channels are enabled): In the case of a thermocouple input, the Burnout check is carried out every 10 seconds. The duration of this check takes a sampling on each enabled thermocouple channel. For example, with 3 active thermocouples, every 10 seconds the following are used: 4ms x 3 channels = 12 ms for Burnout evaluation.
ATTENTION!
IF ANALOG INPUT 1 IS CONFIGURED IN RTD PT100 MODE, THE MINIMUM SAMPLING TIME FOR THIS CHANNEL TO OBTAIN A CORRECT MEASUREMENT IS 25 ms
2.4.2. DIGITAL I/O UPDATE TIME
The update time of the 8 digital I/Os is 4ms.

2.5.1. LOAD CELL CONNECTION
It is possible to connect the converter to the load cell in 4- or 6-wire mode. 6-wire measurement is preferable for measurement accuracy. The load cell power supply is provided directly by the device.
2.5.2. 4- OR 6-WIRE LOAD CELL CONNECTION
A load cell can have a four-wire or six-wire cable. In addition to having the +/- excitation and +/- signal lines a six-wire cable also has the +/- sense lines. It is a common misconception to think that the only difference between 4- or 6-wire load cells is the possibility of the latter to measure the actual voltage at the load cell. A load cell is compensated to work within specifications in a certain temperature range (usually -10 – +40°C). Since the cable resistance depends on the temperature, the response of the cable to temperature changes must be eliminated. The 4-wire cable is part of the load cell temperature compensation system. The 4-wire load cell is calibrated and compensated with a certain amount of cable connected. For this reason, never cut the cable of a 4-wire load cell. The cable of a 6-wire cell, on the other hand, is not part of the load cell temperature compensation system. The sense lines are connected to the R-SG3 sense terminals, to measure and adjust the actual voltage of the load cell. The advantage of using this “active” system is the possibility of cutting (or extending) the 6-wire load cell cable to any length. It must be considered that a 6-wire load cell will not reach the performance declared in the specifications if the sense lines are not used.
2.5.3. CHECKING THE LOAD CELL OPERATION
Before starting the configuration of the device it is necessary to verify the correctness of the wiring and the integrity of the load cell.
2.5.3.1. CHECKING CABLES WITH A DIGITAL MULTIMETER
First you need to check with the load cell manual that there are about 5V DC between the +Excitation and Excitation cables. If the cell has 6 wires check that the same voltage is also measured between +Sense and Sense. Now leave the cell at rest (without the tare) and check that the voltage between the +Signal and Signal cables is around 0 V. Now unbalance the cell by applying a compression force, checking that the voltage between the +Signal and Signal cables increases until it reaches the full scale (if possible) where the measurement will be approximately:
5 (cell sensitivity) mV.
For example, if the declared cell sensitivity is 2 mV/V, 5 2 = 10 mV must be obtained.

Doc: MI-00605-9-EN

Page 9

User Manual

R-P SERIES

In the case of bipolar measurement only (compression/traction) it is necessary to completely unbalance the cell even in traction, in this case the same value must be measured between the +Signal and Signal cables but with the negative sign:

-5* (cell sensitivity) mV.

2.5.4. CONNECTION OF MORE LOAD CELLS IN PARALLEL

It is possible to connect up to a maximum of 8 load cells (and in any case without ever falling below the minimum 87 Ohms).

It is therefore possible to connect:

IMPEDANCE OF THE STATED LOAD CELL
[Ohm] 350
1000

NUMBER OF LOAD CELLS IN PARALLEL MAXIMUM NUMBER OF CONNECTABLE CELLS IN PARALLEL
4 8

For the connection of 4 load cells Seneca recommends using the SG-EQ4 product.

To connect 2 or more 4-wire cells in parallel with the SG-EQ4 junction box, use the following diagram:

R-P SERIES

To connect 2 or more 6-wire cells in parallel with the SG-EQ4 junction box use the following diagram:

For more details, refer to the SG-EQ4 Junction Box accessory manual.
2.5.5. TRIMMING 4-WIRE LOAD CELLS The figure below shows a diagram of three trimmed load cells.

A variable resistor, independent of the temperature, or a typically 20 potentiometer is inserted in the +Excitation cable of each load cell. There are two ways to trim the load cells. The first method is to adjust the potentiometers by trial, shifting the calibration weights from one corner to another.

www.seneca.it

Doc: MI-00605-9-EN

Page 11

User Manual

R-P SERIES

All the potentiometers must be adjusted so as to set the maximum sensitivity for each cell, turning them all completely clockwise. Then, once the angle with the lowest output is located, act on the trimmers of the other cells until obtaining the same minimum output value. This method can be very long, especially for large scales where the use of test weights on the corners is not very practical. In these cases the second, more suitable method is to “pre-trim” the potentiometers using a precision voltmeter (at least 4 1/2 digits). You can use the following procedure: 1) Determine the exact mV/V ratio of each load cell, shown in the calibration certificate of the cell itself. 2) Determine the exact excitation voltage provided by the indicator/meter (for example Z-SG), measuring this voltage with the voltmeter (for example 10.05 V). 3) Multiply the lowest mV/V value found (point 1) by the excitation voltage (point 2). 4) Divide the trimming factor calculated in point 3 by the mV/V value of the other load cells. 5) Measure and adjust the excitation voltage of the other three load cells using the respective potentiometer. Check the results and make a final adjustment by moving a test load from corner to corner.

5.5.4. R-SG3-P
FUNCTION MODE It allows to configure the basic operation of the device, can be set to factory calibration or to Calibration with standard weight:

FACTORY CALIBRATION It is used when a load cell with declared sensitivity is available. In this mode, calibration only consists in acquiring the tare directly in the field with a direct measurement. If it is not possible to acquire the tare with a direct measurement (for example in the case of an already filled silo) it is possible to manually enter the tare value in the desired unit of measurement (kg, t, etc.).

CALIBRATION WITH STANDARD WEIGHT It is used when a standard weight is available (as far as possible towards the load cell full scale). In this mode the calibration consists in acquiring both the tare and the standard weight directly on the field.

MEASURE TYPE It allows to configure the operation of the device between:

BALANCE (UNIPOLAR) It is used when a scale is being created in which the load cell is only compressed, in this case the maximum resolution of the compression measurement is obtained.

COMPRESSION AND TRACTION (BIPOLAR)

www.seneca.it

Doc: MI-00605-9-EN

Page 32

User Manual

R-P SERIES

It is used when a measurement system (typically of force) is being created that can both compress and extend the load cell. In this case the direction of the force can also be decided, if compression the measurement will have the + sign, if traction it will have the – sign. A typical case of use is to link the direction of the force to the analog output so that, for example, 4mA correspond to the maximum traction force and 20mA correspond to the maximum compression force (in this case the cell at rest will provide 12Ma).

MEASURE UNIT Sets the unit of measurement for the weighing in g, Kg, etc.

CELL SENSITIVITY It is the declared cell sensitivity value expressed in mV/V (in most cells it is 2mV/V).

CELL FULL SCALE It is the full scale value of the cell expressed in the selected unit of measurement.

STANDARD WEIGHT VALUE It represents the value of the standard weight that will be used in the calibration if the operating mode with standard weight has been chosen.

NOISE FILTER Enables or disables measurement filtering.

FILTER LEVEL Allows you to set the measurement filter level according to the following table:

FILTER LEVEL 0 1 2 3 4 5 6
ADVANCED

RESPONSE TIME [ms] 2 6.7 13 30 50 250 850
Configurable

The higher the filter level the more stable (but slow) the weight measurement will be. If you select the advanced filtering level (Advanced), the configuration will allow you to select the following parameters:

ADC SPEED Selects the ADC acquisition speed from 4.7 Hz to 960 Hz

R-P SERIES

NOISE VARIATION It is the variation in ADC points due to noise alone (represents the measurement uncertainty due to noise) or how much we expect the measurement to vary (the unit of measurement is in raw ADC points).
FILTER RESPONSE SPEED Represents a parameter related to the filter response speed, it can vary from 0.001 (slowest response) to 1 (fastest response). Represents the variance of the process.
NET WEIGHT RESOLUTION It is the resolution with which the value of the net weighing is represented, it can be worth:
MAXIMUM RESOLUTION It will represent the net weight with the highest possible resolution
MANUAL It will represent the net weight with the manual resolution set (in engineering units). For example, by setting 0.1 Kg you will get that the net weight can only vary by multiples of 100g.
AUTOMATIC RESOLUTION It will represent the net weight with a calculated resolution of about 20000 points. Unlike Maximum or Manual resolution, this setting limits also the ADC value and therefore affects all measurements.

CAUTION
Keep in mind that in the “Calibration with standard weight” mode, using the “Manual Resolution”, the correct standard weight value may not be perfectly represented:

Cell full scale 15000 g Standard weight 14000 g Manual Resolution 1.5 g

For example, you have:

The value of the standard weight (14000 g) cannot be represented with the resolution in 1.5g steps (14000/1.5g = 9333.333 is not an integer value) so it will be represented as: 9333*1.5g = 13999.5g To avoid this effect, use a resolution that allows the value to be represented (for example 1g or 2g).

SAMPLE PIECE WEIGHT

Sets the weight of a single piece in technical units for the mode. By setting the net weight of a single element in this register, the converter will be able to indicate the number of pieces present in the scales special register according to the relation:

AUTOMATIC TARE TRACKER It allows you to enable or disable the automatic tare reset.

ADC VALUE It allows to set the number of ADC points within which to reset the tare automatically. If after 5 seconds of stable weighing condition the ADC value of the net weight deviates by less than this value then a new tare is acquired.
DELTA WEIGHT Weight variation that contributes to the definition of “Stable Weight”
DELTA TIME [x100ms] Time variation that contributes to the definition of “Stable Weight”

STABLE WEIGHT (Stable weighing condition)

The stable weighing condition is used to indicate that the net weight measurement is stable if:

The net weight remains within the weight _ over time or if the slope of the curve drawn

by the net weight is less than

6.1.2. INSTALLING THE GSD
Now you need to connect the Seneca slave device PROFINET IO to the profinet master (controller). First install the GSD file of the Seneca IO. Select Tools->Device Repository:

Now import the GSD file by selecting Profinet IO Slave and then Install:

Now point to the correct folder and press OK. Codesys has now added the GSD file correctly.
At this point you can scan the network in search of Slave devices (Device).

The PLC (Raspberry-pi) is quite slow and not real time, consequently it cannot manage the profinet at maximum speed so we modify the values by setting safety parameters:

6.1.5. READING AND WRITING THE SENECA IO FROM CODESYS
Now see how it is possible to read and write IO on the Seneca device. To write and read the status of the IO you have to insert a few code lines under PRG. In the program, read the inputs from the %IW2 address and write in the %QB0 address as it is obtained from here:

Declare an 8-bit (Word) variable for the 16 inputs and one byte for the 8 outputs. In the program, instead, read the inputs from %IW2 and write the outputs on %QB0:

Go into login and start.

The value of the inputs can be read here:

R-P SERIES

while to write the outputs you just set the byte value in the “prepared value” column, for example by writing 255 decimal = 11111111 binary all the outputs will be brought to 1:

And then with “Write values” all the outputs are activated correctly.

7. CABLE HARNESS FOR MODELS WITH DOUBLE ETHERNET PORT
Models with double Ethernet port can be connected in daisy chain and take advantage of the Lan Fault Bypass.
7.1. CHAIN ETHERNET CONNECTION (DAISY CHAIN)
Using the daisy chain connection it is not necessary to use switches to connect the devices. An example (in this case on R-16DI-8DO-P) of connection of 3 devices is as follows:

ATTENTION!
IT IS NOT POSSIBLE CREATE LOOPS WITH ETHERNET CABLES

If it is necessary to connect the devices to the switches, correct wiring is as follows:

In the Ethernet wiring there must be no loop, otherwise the communication will not work, some examples of incorrect wiring are the following:

7.2. LAN FAULT-BYPASS FUNCTION
The LAN fault-bypass function allows you to keep the connection between the two Ethernet ports of the device ON, in the event of power failure problems. If a device turns off, the chain is not interrupted and the devices downstream of the switched-off one will still be accessible. This function has a limited duration: the connection remains active for a few days, typically 4. The Lan fault-bypass function requires that the sum of the lengths of the two cables connected to the switched off module is less than 100m.

8. SEARCH AND MODIFICATION OF THE DEVICE IP WITH SENECA DISCOVERY TOOL
When in the R series device the STS LED is on steady, it is possible to obtain the IP address which has been set using the “Seneca Discovery” tool too.
The software can be downloaded from:
https://www.seneca.it/en/linee-di-prodotto/software/easy/sdd
Pressing the “search” button starts the search for all Seneca devices present in the network even if with IP addresses not compatible with the current PC configuration:

It is now possible to change the address by pressing the “Assign” button:

The software works on layer 2 level and it is therefore not necessary to have an Ethernet configuration compatible with the device you are looking for.
ATTENTION!
AS LONG AS THE STS LED IS FLASHING IT MEANS THE DEVICE HAS NOT SET AN IP ADDRESS. IN THIS SITUATION IT WILL NOT BE POSSIBLE TO SEARCH FOR THE DEVICE WITH THE SENECA DISCOVERY TOOL SOFTWARE

9. FIRMWARE UPDATE
The firmware update can be performed via the web server in the appropriate section.

R-P SERIES

ATTENTION!
BEFORE ACCESSING THE WEB SERVER, DISCONNECT THE DEVICE FROM THE PROFINET NETWORK
ATTENTION!
NOT TO DAMAGE THE DEVICE DO NOT REMOVE THE POWER SUPPLY DURING THE FIRMWARE UPDATE OPERATION.

ATTENTION!
THE DEVICES ARE SUPPLIED BY THE FACTORY WITHOUT AN IP ADDRESS (0.0.0.0) IN THIS CASE THE “STS” LED FLASHES.
TO SET AN IP ADDRESS (FOR EXAMPLE TO ACCESS THE WEBSERVER OR TO CONNECT TO THE SENECA DISCOVERY DEVICE TOOL) USE THE PROFINET CONFIGURATION ENVIRONMENT OR FORCE THE ADDRESS 192.168.90.101 WITH THE APPROPRIATE DIP SWITCH
