We’re looking at replacing a GE Mark V control system \< I \> operator interface with Ignition. Matrikon make an OPC server which communicates using the Mark V Stagelink protocol. One of the features of the Mark V is that it sends out unsolicited event messages which the Matrikon server makes available using an OPC DA A&E (Alarms and Events) interface.

Has anyone successfully read information from an OPC DA A&E server into Ignition?
