OPC UA Alarm & Condition

Post by nemesis »

Hi,

Can anyone explain how the event areas and event sources can be created to create the AddressSpace in OPC UA AC server dynamically? I need to simulate the creation of Condition events from a client to push change of state so that subscribers to those event and alarms can be notified of these notifications.

Thanks.

Hi,

The creation of Alarm objects, source nodes and areas is SDK specific. But you should be able to use the same examples provided for creation of such nodes at any time. Typically the nodes are created during server start-up but this can be done later too.

Examples for the C++ SDK can be found here:
http://documentation.unified-automation ... son06.html

The sample code for the creation can be executed for new objects later on.

Best Regards,
