I have a redundancy alarm "Redundancy: Not Communicating - Secondary Network" occurring multiple times over the course of some minutes in infrequent and inconsistent times on two separate SIS SZ controllers. Each time the alarm will clear 10 seconds later. I have changed out the network port to no avail. Diagnostic monitor indicates the redundancy is good for each controller. Is there anything else to be looked at? I suspect this is being caused by heavy network traffic. Is it possible to put a delay on the controller alarm such that it will only alarm under a sustained alarm condition? Thank you for any assistance.
