Configure the Alarm Control to require an ACK signature

Even if you are logged into the InTouch application, 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. Place an Alarm Control in the drawing canvas.

2. Double-click the Alarm Control on the canvas. The Edit Animations dialog box appears.

   

3. Click Run-Time Behavior. The Run-Time Behavior page appears.

4. Select the Requires ACK Signature check box. The Min Priority and Max Priority boxes are enabled.

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

6. Click OK.

You can configure the alarm signature requirement as well as the minimum and maximum values in run time using the Object Editor. For more information about using the Object Editor, see the Application Server User’s Guide, Working with Objects.

For more information about configuring the Alarm Control in run time to require an alarm acknowledgement signature, see the "SignedAlarmAck() Applied Examples" topic in the Creating and Managing Industrial Graphics User’s Guide.

Note: If your computer supports Smart Cards, you can use them for alarm authentication at run time. You need to have the Smart Card mapped to your user account in the domain. If the Smart Card is already in the reader and you enter the correct PIN, the system will allow you to acknowledge the alarms.
