Ran into an issue the other day where a network of PLC's (3 PLC5's with ethernet sidecars and a single SLC 5/05) all faulted at the same time. The PLC5's showed coprocessor faults, which I believe is an issue with the ethernet modules attached to the processor. The SLC 5/05 showed a hard fault on the ethernet comm port, and even went as far as to disable this port while it was faulted. I was able to connect with a DF1 driver and see this before resetting this.
Has anyone else seen this type of behavior where all the processors on an ethernet network fault like this? This also happened about 4 months ago when we only had the three PLC5's on the network.
