Potential Failure in Detecting Certain Alarms

SUMMARY

AVEVA has identified an issue with System Platform 2023 and System Platform 2023R2.

Under certain circumstances, Limit, ROC, and Deviation alarms on UserDefined and Area objects may not function correctly at runtime. This issue occurs within the engineering environment and can result in the alarms not getting registered with the AppEngine at runtime.

AVEVA is releasing hotfixes for each of the affected versions. Details can be found in the table below.  AVEVA strongly recommends that users install the appropriate hotfix as soon as possible.

APPLIES TO

• AVEVA System Platform 2023 and 2023 R2 (including patches)

PROCEDURE

Apply the appropriate Hotfix

1. Download and apply the hotfix for the appropriate version:

• Follow the steps in the included ReadMe file.
• Hotfix is only applies to the Galaxy Repository (GR) node.

Detecting the issue

2. Download and run the AlarmIssueDetection.ps1 PowerShell script.  If the issue is present, the script will return a list of any affected templates.
   Alternatively. you can run AlarmIssueDetection.sql using the galaxy database in Microsoft SQL Server Management Studio.  Both methods will return the same results.

Redeploy any affected instances

2. Undeploy any instances that are derived at any level from the returned list of templates.
3. Once undeployed, re-deploy the instances to resolve the issue for runtime.

NOTE:

* The detect and redeployment of the instances affected by this issue only needs to be done 1 time after installing the hotfix. After following the steps to resolve the issue, running the detection script will still return the same results.

** Hotfix must be installed whether or not results are returned in step 2.
