Do you guys have RS485 communication example code?
I would like to receive example code as Python code.

Hello Sir Ulrich. I'm still new here and I cannot post on my own. My problem is related to RS485. Im currently using the RevPi Connect 4 via CODESYS. I wired my actuator to the RS485 of the RevPi Connect 4 and it seems it was not recognized . What solutions should I do? In my previous projects using RevPi Connect not the one Im using right now my Slave was being recognized but now using RevPi Connect 4 it was not recognized. Maybe you could help me Thanks.

Hello Joshajtitus,
please have a look at this article and check the connection of your Connect 4 to your slave.
