Hi all,
I've been making good progress with the WWTP lightning strike issue, CPU and I/O for the Plant PLC is up and running, and data is coming through to the HMI (RSView32). However, a remote Filter PLC is not communicating.
What's odd is that the Plant PLC is connected via "direct driver" but the remote Filter PLC is connected via OPC Server. Why there would be two methods of connection is beyond me, I didn't design this system and it looks like it has been piece-mealed together over the years.
The OPC Server signals are all blank and when I go to RSLinx and look at the data monitor, there are values there but they are unchanging so obviously it's the last recorded value. If I go to the OPC/DDE menu and select Active Topics/Items, every item under the topic of Filter PLC has an error message that says "STATUS ERR $5". Lots of google searches later, I haven't found much about that error.
I've never set up an OPC Server so I'm not really sure how to diagnose what's going on here, any suggestions for how to troubleshoot would be much appreciated. Thank you!
edit: I should mention that I can online to the PLC via Logix500 so at least there's that.
