SignedAlarmAck() scripting tips

SignedAlarmAck() and alarm configuration

You can use the SignedAlarmAck() function only in client scripts supported by your HMI/SCADA software.

SignedAlarmAck() with OnShow and OnHide scripts

We don't recommend using the SignedAlarmAck() function with OnShow and OnHide scripts. This can cause issues with window functionality, including the window title bar, windows losing correct focus, and windows opening on top of one another.

SignedAlarmAck() with while true scripts

We don't recommend using the SignedAlarmAck() function in a While True script type. A signed alarm acknowledgement requires user interaction. If you want to use a While True type script, set it to an execution time of 30-seconds or longer to allow the user to enter the required information.
