Jack, If I recall the 8.4.2 upgrade seemed to be a fairly insignificant and quick upgrade for workstations using only one CD and taking only a few minutes. I don't think the 8.2 splash screen accessed from the Initial display gets updated so it was hard to tell if 8.4.2 was really installed. I do know it caused the symptoms described by you plus some others.

I lean towards it being an AIM Historian issue, as only 3 out of 7 AIM Historian alarms come up with the "No Alarms Found" error message in Alarm History, no matter which workstation you use. I see others have the same issue and have gotten no help from Fox either.

When we upgraded the historian server to 8.4.2 none of the 8.2 boxes could call alarm history from it. If we also upgrade two workstations out of sixteen then those two workstations could call alarm history from the 8.4.2 historian server. But the other 14 at 8.2 could not. Check to see if the wotkstations that aren't able to call alarm history are actually at 8.4.2. There were a lot of problems with alarms and CAG's Common Alarm Groups introduced at 8.4.2 because Foxboro changed the underlying communication mechanism. If you go from 8.2 to 8.4.2 it is best to do it all at once or you will likely have some funky problems with the alarm substructure.

We are at Version 8.4.2. What was the solution?

There was a known problem that we experienced when I was in Hawaii when we upgraded from 8.2 to 8.4.2. This was one of the symptoms. No alarm history. Sent from my Verizon Wireless BlackBerry -----Original Message----- From: <Jack.Easley@xxxxxxxxxxxx> Date: Wed, 2 Jun 2010 08:54:26 To: <foxboro@xxxxxxxxxxxxx> Subject: [foxboro] Another Alarm History Issue Three out of seven of my Alarm Histories are not working (No alarms found error message). However, the AIM Historians are saving all of these recent alarms, as I can use apitst to see them. The problem is just with the Alarm History callup. Anyone else experience this???
