Hi All,
I have a question would like to ask the experts: my system has two Rx7i PLCs and I'm having them communicate with an RTU (D25) via modbus RTU serial. Is there a way to monitor the communications between the PLCs and the RTU ? Is this something that can be done in the PLCs or it must be done in the RTU ? Sometimes the communication between one PLC to the RTU is lost but I don't know which one until getting to the site.
Thanks.
