Hi, I'm following the example project from Edwin and I'm having an issue with the communication. I'm using a raspberry pi connected to a motor controller via USB Serial port ttyACM0. I'm trying to send a string of G-Code such as "G1 X10". I added the following to my CODESYSControl.cfg [sysCom] Linux.Devicefile=/dev/ttyACM portnum := COM.SysCom.SYS_COMPORT1; I have verified the communication by sending the command in the terminal. Do I need to set up a ModbusCom device? I'm very new to Codesys, so...
