Hi all, im using 2 PLC M340 and VijeoCitect 7.2 soft. I need to detect with the SCADA when a PLC is not communicating with the VijeoCitect, and inform the other PLC. Basically i would need to know how to do this, if there is a variable that changes when there is a communication error, or something like that. I am managing the communication with the OPC server. Thank you.
