In publication 1785-RN522C-EN-P dated 8/01 Allen Bradley states:
"Under extremely noisy conditions on the ControlNet channel, processor may fault with memory loss or lose communication."
I have seen this (complete memory loss) happen from time to time, sometimes on just one PLC on the network and sometimes to more than one. I am looking for information on how to measure the health of the ControlNet system. Are there any hardware/software products that can tell me the system health? Are there any specs available for me to use an o-scope or other test gear to test the system?
Thanks,
Ed
