I'm having issues with establishing communication with Arduino UNO to Raspberry PI via Codesys on my PC.
My current connection at the moment:
PC with Codesys V3.5 SP16 patch 3 connected to Raspberry PI with ethernet cable and from Raspberry PI it's connected to Arduino UNO with usb cable (A-male to B-male usb cable). The issue is that I can't figure out how to establish connection with the Arduino UNO from Codesys (via Raspberry PI), the modbus slave com port can not run the bus.
I want to be able to read the digital inputs from the Arduino UNO in Codesys.
