I currently using my plc to ack alarm. Most of my operator station do have a hardwire button for ack alarm. I would like to remove the ack logic in my plc and let ignition deal with this. I try this code in a gateway script to ack all alarm in a specific system like this system.alert.acknowledgeAlert("SQLTags.MyArea"."*","*") But this is not working. Is there a way to do this?
