Dear All,
We have a machine with 6 Racks of GE Fanuc 90-30 series , with CPU374 Plus.
We keep taking 'loss of I/O module' and 'add'n of I/O module' faults while standing still and in time it turns into a 'system configuration mismatch' alarm. This happens only in Rack-2. This error causes the CPU to go to STOP position.
I've replaced :
*CPU
*baseplate of main rack
*baseplate of Rack-2
*all cables between expansion racks
*terminating resistor
*All modules on Rack-2 (all 10 are DI)
*Power supplies of main rack and Rack-2)
None of them has solved the problem.
Any ideas?
Thanks in advance,
Emre
