Configure the AlarmApp to require an ACK signature

Even if you are logged into the AVEVA OMI ViewApp, acknowledging the alarms that fall within a specific priority range may need to be authenticated by you if required by your company or industry. You can configure the Alarm Control to provide such functionality by selecting the Requires ACK Signature check box in the Object Properties dialog of the Alarm Control.

After the Alarm Control has been configured to require a signature for acknowledgement, you need to set its minimum and maximum priority values. The valid range of the minimum and maximum priority values is 1 to 999.

To configure the Alarm Control to require ACK signature

1. Select the Alarm Control placed on a pane.

2. Select the Properties grid to show Alarm Control properties.

3. Select the ellipsis button shown at the right of the Configuration field to show the Alarm Control's Configuration dialog box.

4. Click the Run-Time Behavior tab. The Run-Time Behavior page appears.

   

5. Select the Requires ACK Signature check box. (You may need to scroll the left column to make it visible.) The Min Priority and Max Priority boxes are enabled.

6. Enter the minimum and maximum priority values for the alarm range window that will require authentication.

7. Click OK.

You can configure the alarm signature requirement as well as the minimum and maximum values in run time using the Object Editor.
