How do we ACK alarms on an HMI from a PLC bit?

Published date: 24 July 2019

Issue:
Looking for a way to programmatically ACK alarm on the HMI from a PLC bit.

Product Line:
Vijeo Designer, Vijeo Designer Runtime

Resolution:
To allow a PLC bit to ACK all alarms displayed in the Alarm Summary, the following script call should be made in a Panel Action (on the same panel as the Alarm Summary).

<Alarm Group name>.ackAll();

Note: The action should be configured as Conditional and to execute when the PLC bit is "True".

The attached project makes use of a Panel Action that executes an AlarmGroup script when a PLC bit is "True".

Please see the attached project for the example.
