Hi Ev1
I'm presently working on one of the old PlC by Omron
"SYSMAC CV–series CV500/CV1000 CVM1 CPU21". and I am a amateur in this field.
Now my main problem is the WDT ( Watch Dog Timer ) Error., Due to which
the entire systems goes into a reset condition & I'm unable to debug or in other words view any of the signals.
So I wanted to know what are the different conditions that causes this WDT error to go High.
And I also want to know if any timing violations cause this error if so what is the best
way to come out of this condition
& if anyone has worked on this board , can they please give me the list
of signals that are effecting the WDT.
There is a processor 80C186 being shared by TF250LF & TF 142NF, Can anyone
give me the detailed operation happening between them.
I'm very greatful for ur consideration.
Thanking You,
Grac Mascarenhas
