Hi everyone,
I'm trying to go online with an IFM PLC over a serial connection, using CoDeSys. Things were working fine for a while; I managed to upload a program to the PLC, and it is currently running on the PLC. However, I am now no longer able to connect to it over serial.
I repeatedly get Communication Error #0. I've tried using a different laptop, I've triple-checked all connections, I've switched comm ports and baud rates and am still receiving the error. I also used a line monitor to observe the serial connection, and observed that the received transmissions from the PLC appear strange. See the image below for details.
Any help is greatly appreciated! Thanks
