Scenario:
I have a network consisting of the following:
3 - AB SLC500
1 - AB PLC5
2 - RSView32 HMI pc's, w/RSLinx 2.42
4 - GE quickpanel
1 - AB 6182 PC/touchscreen
1 - N-Tron 524TX to tie it all together.
Last week, I installed the N-tron. This was to do two things: provide a more managed network, and to work on 24V instead of 120V.
Three days later - I get a call that one of the RSView PCs is not communicating. So, diagnostics reveals:
The PC is talking to the 3 SLC's, but not the PLC5. RSLinx, "WHO" utility, verifies that the PLC-5 is NOT THERE, apparently. The other PC is working fine, BTW.
In troubleshooting:
I can ping the PLC-5 from the PC.
I plugged my laptop in to the same port, saw everything on the network.
I swapped ethernet cards.
I reseated the cards.
I restored a ghost backup from 3 years ago that was working.
I moved the PC to another drop.
I swapped cables in the switch.
Still can't see the PLC-5 with only the one PC.
What is wrong? I have not done any administrative things with the N-tron, I wanted to see if the comm problems I was having would go away before tweaking the network.
Our only resolution at this point is to replace the PC. But... this is one of the strangest problems I have ever seen.
I have a queasy feeling that the N-tron switch is "following" this PC, but I can't really see how.
Ideas?
(when I call for tech support, yes, it is a GOOD ONE!)
