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.
