changing alert handler active value from other system

[vedadramovic]

Hello,
How is it possible in distributed system to change alert handler activity value from one of the systems in distributed system?

I have tried to change it using dpSet() and using "para", but I did not succeed.
I need this to disable specific alarms during regular system tests. During those tests we need to have values from those data points.

Best regards,
Vedad Ramovic

Hello,

setting the attribute _alert_hdl.._active is possible with a dpSet(), even in a distributed system.
Before an alert handling can be set inactive all pending alerts for the specific DPE must be acknowledged.

You could also consider using the event config entries 'alertConditionBit' and 'alertConditionLogic', so you can temporary disable the alert handling for a dpe by setting an userbit. This way a pending alert does not have be acknowledged.
Only do not forget the activate the alert handling again after the system tests are done.

Thank you very much Leopold and Gertjan for fast and precise answer.

In my case "para" was opened on original system and it locked the element, so I was not able to change it from distributed system.
