my plant has a honeywell TDC3000 DCS system with a software release 435. the problem that i need help on is that for now 3 months from time to time i face a total LCN node shutdown, all nodes fail with error code -190, and i have to reload them all, sometimes the 4 HMs i have get rebooted and sometimes i have to laod them manually, the problem is that could possibly be a cause for all nodes to fail when i don't have any power failure or problem with it.
 
Sounds like an NCF problem, for more than one node to fail. I'd suggest you get help from Honeywell TAC.
We had an HM fail intermittently with the same code, but that was a single node failure. It turned out to be a bad circuit board in the 5 slot module chassis...
 
We are facing issue in NIM failure of TDC3000 system and every time Error is -190. Two redundunt NIM . Nim 07 & NIM 08 . Every time NIM 7 is being failed every two / one day interwal.
