We have a cell that was done by an integrator. It has lots of intermittent comms issues that sometimes are minor and sometimes doesn't allow you to even ping the PLC compactLogix when connected to the LAN of the cell, but the cell can sometimes still function even in these instances.
Today I noticed there were 2 devices connected to a Balluff field network switch (BNI0089) that were not communicating even though they had link lights on. There were 4 other devices connected to this switch and they were all communicating properly. I tried power cycling the switch and it made it so all the devices stopped communicating.
I talked to some techs that had similar issues with this, and the ultimate fix is to power cycle the whole cell, but I can't do that at the moment or do i think it should be like that at all.
Any ideas?
