We have started getting the following error after years of service. These never shut down our system but I am afraid something is wrong and will eventually cause us issues.
FAILED Both SIS Net Connections on Logic Solver are Bad
MAINT SIS Net Error
ADVISE SIS Net High Error Rate
Seem to be getting a lot of P2Pstatus alarms as well which I believe is the communication between the modules?
We have 4 redundant pairs of 1508s and each one gets these errors, sometimes all at the same time but not always. Any ideas of what might be causing the problem?
