We are having a reoccurring issue between our PLC5 processors and our HMIs. 3 times in the last five days we have lost communication from the HMI to several PLC5 processors. This is happening in two of our control rooms. The network itself appears to be fine with no other issues. For example, from the pulpit HMI, I can use two command windows and continuously ping a workstation and a PLC in the same control room. The PC will respond 100% to the pings while the PLC5 will drop 30% of the request.
While searching for a solution, I found this error message in the driver diagnostic file for RSLinx:
Datestamp 192.168.26.5 Error receiving data from the Ethernet Interface
Datestamp 192.168.26.5 [10054] Connection reset by peer
This message repeats for each of the PLCs the driver is configured for. Approximately an hour later, We receive:
Datestamp 192.168.26.5 Initiated a new connection
After this, all the processors will communicate as they should. Any help yall could give would be greatly appreciated.
Thanks,
Rab
