Hello,
As you may remember, I posted in January about an issue we were having with our micro850 controllers (2080-LC50-48AWB) to operate irrigation booms in our nursery. Previous thread link - http://www.plctalk.net/qanda/showthread.php?t=127884
I was in touch with Rockwell, and they had 2 ideas:
The issue we're facing is very random, so it's difficult to tell if the change you made helped, or if it wouldn't have been an issue during that time frame. So I swapped the plugin slots for a couple cards, and had no issues, but the device wasn't causing issues for a few days before the swap either... I swapped the cards back, and still no trouble...
Rockwell's second thought is to try suppressors for the outputs (we are using all but 2 of the 16 outputs. We're very tight on space in the panel - do any of you have ideas of what suppressor to try? It looks like Rockwell's supressors are a little too bulky to fit in the space we have. We're using 24vac solenoids on the outputs.
Also - random is very difficult to troubleshoot. When you have 65 devices, and any one of them randomly malfunctions once every couple weeks (no same 2 in a row) - any thoughts of how to try suppressors would also be welcome :-(.
Many thanks,
Shama
