Network Access Points / (WDS) Wireless Distribution System

If your network is operable (at least most of operating time) it's believed configured properly. Some of switches are sensible to power supply noises. It could be a reason.

I would suggest you to add at your network some abundance as one more reserving routers(switches) in case if a main route falls. Is it possible?

Thank you for your response!

My switches are 24vdc powered from the same power supply as the relays. A possible problem, thank you. The fractional bandwidth I require did not neccessitate an additional router for redundancy. The wired portion of the network has never had a problem. When my "wireless" connections get interrupted, the "wired" connections continue without any interruption.

Any additional thoughts?

You've said "the same power supply as the relays"? How they are rated? Just today I had a problem with wire 485 network connected to PC. When relay was switching I forced to replug my USB-485 connector as communication error occurred.

As for "wireless connection get interrupted", I'm wondering could you program the PLCs in such a way that if so it could be re-started by a WatchDog timer then resets itself and reload program with an recovered communication configuration. It could as well to try get restarted a problem switch(s).

The com problem you described might be theoretically caused (barely) "contaminated" memory registers(stacks) in PLC due to industrial noise.

Yes, I'm leaning toward "industrial noise" as I have had the same installation at another site without a problem. The only difference was the revision of the Engenius EOC-8610 AP. I am visiting the site on Monday, 11/10/08, and will make a few modifications. I will keep all informed?
