Event properties

The server’s address space exposes the fields and properties associated with each event type available.

Event notifications from alarms and conditions are processed by the OPC UA adapter. When an alarm is triggered, you are notified through an event notification. Event fields from the incoming event notification are extracted and concatenated into a string with a delimiter as specified in Configure client settings.

The event notification displays the fields specified when the alarm was configured. For example:

Low fluid pressure | 1 | Pump 3A

You can configure the event fields of interest that are sent in the egress string. This can be done using the EventProperties parameter of Data Selection Configuration.

Event subtypes inherit the properties of their base and have access to all properties starting with BaseEventType. Discovery results list all the available and inherited properties by default.
