Marc, Yes, that is common problem we have seen. One recent occurrence was when we upgraded a workstation with AIM 3.3.x from XP I/A v8.2 to v8.4.4. We haven't resolved it yet. I have been told, though, that it might be that there are too many alarm messages in the historian. We only keep 60 days, so I'm not sure that is the problem. It's also been hit or miss if it works since going beyond FV10.2 on our XP I/A v8.2 Operator workstations and beyond I/A v8.2 on our AIM hosts. Thanks, Philip Pulas Tesoro Companies, Inc.

About a year ago, we had deleted several point out of the working historian (AIM 3.3) in order to free up some points to add others back. Operations has informed us that they no longer have alarm history within the CAD displays. We reconfigured the AIM database to collect alarm messages, but when testing, historical alarms were not present. Anyone know of anything else that should be changed in order to enable CAD alarm history? CAD is in fact pointing to the correct historian and its connecting and the historian is building the m* files in its directly. Help, advice, encourage words always welcome.
