Has anyone successfully used the GROOV EPIC PR2 with CSERI-4 (CODESYS) as Modbus Polling master?
If so, I would appreciate example code. I have not been able to find it.

Welcome to Opto 22!
There are a few different ways to connect to modbus serial data using the groov EPIC. Below are three of them.
PAC Control:
You can use the Modbus Integration toolkit from Opto 22 to configure your modbus connections and registers to poll. Here is the technical note regarding the implementation. You can find the modbus addresses in groov Manage→System→Serial Devices:
Codesys:
You can find the steps in the Codesys Helpme site.
Similarly the addresses for serial device can be found in groov Manage.
Node Red:
You can also use node red to connect to modbus serial devices. We have a video walking through the steps to accomplish this.
