Good day, I have an issue between an M340 PLC and a PRA 0100. The problem is as follows: I have a communication link between the PLC and the PRA controlling a process. However, at a certain point, the entire process stops without any faults in either the PLC or the PRA. After monitoring, the following occurs: an input module flashes at a certain moment and then the process halts. This observed detail is akin to pressing the stop button, which is not the case. I suspect it may be a backplane issue or a faulty module.
