Hi, I am writing to you because I have a problem in a communication with an S7 1200 PLC.
Normally it works correctly, but once or twice a day an error is generated that is registered in the log.
The variable is a bit in the memory position M1.1 in the PLC that is written to change its value from 0 to 1.
The error is as follows:

I do not know why it happens.
Somebody could help me?
