[MSI Interface] Deleting an Alarm Event Group prevents sending of Exception Messages

[MSI Interface] Deleting an Alarm Event Group prevents sending of Exception Messages

Summary

In the Werum MSI Interface, deleting an alarm/event group leads to an error under certain conditions. This has been fixed.

Description

In the MSI configuration an alarm/event group is used to define an exception message. Later, a group is deleted that was created before the group used in the definition. An internal application error then occurs. This relates to "System.Runtime.InteropServices.COMException".

Cause:

This error occurs because the ID and index were used interchangeably for alarm/event groups. If a lower index is deleted, the function to be executed receives an incorrect index. This leads to an exception. In addition, the wrong alarm/event group was connected in some cases.

This error has been fixed. Deleting a previously created alarm/event group no longer causes an exception error. Alarm/event groups are connected correctly.

To benefit from this fix:

  • Update your zenon Software Platform to the latest build of zenon 11 or higher.

 

Note: If an alarm/event group is deleted, exception messages configured to use this alarm/event group will no longer work. This is logged, but no error occurs in the application.
