AC800M process alarms
I have a question regarding process alarms that I should receive from two AC800M controllers (PM865 HI and PM856A) to 800xA v5.1 rev D.
Up to now, I have received all the other alarms from controllers already connected to the system, but yesterday I connected two mentioned controllers and I have not received their process alarms (their alarm lists are empty, but they are configured in the same way as all the other controllers alarm lists). Controllers are normally connected through OPC server (Data Access; Alarm & Event) and I receive their values from the transmitters in the field.
Does anybody have any suggestion how to resolve this?
Check whether OPC-AE is connected with smiley for these controllers in both OPC servers OPC AE tab of OPC panel(Primary and secondary connectivity server) and ensure that max no of "AE max number of event subscriptions" should be 1 for standalone server and max 2 if two connectivity servers are used, it shouldn't be 0 at any cost.
if configured all properly then disconnect the controllers identity from the OPC AE tab and connect back and if not solve this restart the opc event collector service to rid of the problem at last.
