IAC Communication SIL-3 to SIL-3 Application (PM865 Controller)
I am Using two Redundant PM865 Controllers .I have two seperate SIL 3 Applications in both controllers. I am using 180 IAC commnication Variables which i am communicating From Controller A to B. Now the Issue is that few variables are not communicating (Checked randomly) whereas some of them are working OK with same settings.I have set the Same ISP values and Uniquie ID's with Proper Directions (In in Controller A & Out In Crontroller B) with Expected SIl as SIL3 as both Applications are SIl-3 Configured. but still few variables are not communicating . kindy guide what coudl be the Problem.
Please Find attached Communication Diagnostic for Both Controllers.
As per ur snap in controller A showing less timeouts. Wherein controller B showing more so kindly put the same interval across each variable and don't run all variables in single scan it may cause overrun
And don't use more signals especially controlling signals via IAC
