Use alarm and acknowledgement comments

  • Last UpdatedApr 23, 2025

There are two kinds of comments: alarm comments and acknowledgement comments.

  • The alarm comment is set when the new alarm instance occurs. The .AlarmComment dotfield is used for alarm comments and can be set or read in an InTouch script. You specify the default value for this comment in the tag's definition in the Tagname Dictionary. Alarm comments can be up to 131 characters.

  • The acknowledgement comment is provided by the operator when he or she acknowledges the alarm.

You can use the acknowledgement comment to update the alarm comment in the tag database.

Allow alarm acknowledgement comments to update the .AlarmComment dotfield

  1. Open an application in WindowMaker.

  2. On the File menu, point to Configure, and then select Alarms.

    The Alarms screen appears.

    Select the Retain ACK Comment As Alarm Comment check box

  3. Select the Retain ACK Comment As Alarm Comment check box to update the tag’s .AlarmComment dotfield and the Tagname Dictionary with the comments entered with alarm acknowledgments.

    If you do not select this check box, the acknowledgment comment is shown with the acknowledged alarm (in the database, printouts, and displays), but .AlarmComment does not change.

  4. Select OK.
