Configuring the GPIO Pins
The default GPIO configuration for CODESYS's Raspberry Pi Control Modules does not expose all of the GPIO pins that the ComfilePi offers. To remedy that, it is necessary to modify the device description files typically found attext/html2026-02-20T15:37:35+00:00Anonymous (anonymous@undisclosed.example.com)codesys5

Prepare the Serial port
1. Enable the serial port (sudo raspi-config)
Please choose :
* Login shell accessible function over serial --> NO ;-)
* Enable hardware serial port --> YES
2. Edit the CODESYS configuration file

Add MODBUS RTU device
1. Start a new project.
2. Add device.
3. Select Modbus COM
4. Add Modbus Master.
5. Add Modbus Slave.
Result
6. Now let's modify the Modbus properties.
6.1 Edit the Modbus COM options.
Change it like this to connect with the CUBLOC-MSB later.text/html2026-02-20T15:37:35+00:00Anonymous (anonymous@undisclosed.example.com)codesys10

Interfacing with a CUBLOC MSB
The following demonstrates how to interface with a CUBLOC MSB using the following LD.
Connect the ComfilePi and MSB like this.
1. Add channels.
Please refer CUBLOC Modbus address.
2. Connect Direct Address.
Edit LD, build, Login(deploy), and start.text/html2026-02-20T15:37:35+00:00Anonymous (anonymous@undisclosed.example.com)codesys11

Interfacing with the MODPORT Field I/O Controller
MODPORT is a field I/O product with low price. It is possible to connect with CODESYS.
MODPORT field I/O
Connect MODPORT to RS485 port of ComfilePi.
1. Add Modbus_COM, Modbus_Master, Modbus_Slave.
2. Edit properties.text/html2026-02-20T15:37:35+00:00Anonymous (anonymous@undisclosed.example.com)codesys12

Analog Input and Temperature Sensing
Let's do temperature sensing and analog input using the MODPORT Field I/O Controller.
As a demonstration, connect a potentiometer and a PT100 sensor.
1. Add channels. See the MODPORT user's manual
The final state should look like this
2. Add a POU for MODPORT access.text/html2026-02-20T15:37:35+00:00Anonymous (anonymous@undisclosed.example.com)codesys13

Interfacing the ComfilePi with an EtherCAT Device
EtherCAT field i/o is expensive, but its performance is better than that of Modbus RTU.
(As a result of checking the latency through experimentation, EtherCAT was measured to be about 15~25ms while Modbus RTU was measured to be about 80~100mS)text/html2026-02-20T15:37:35+00:00Anonymous (anonymous@undisclosed.example.com)codesys14

Install a Runtime Lincense
If there is no runtime license, the ComfilePi project will stop after 2 hours. The project can be restarted and run again, but it is recommended to purchase and install a runtime license.
