4.5 Adding event definitions
It is possible to define events for single and double indications. They are added under AE
Event Definitions in the same way as the other objects, see
Creating an object tree on
page 43 . If you want to take a look at an example object tree, see Example of an object
tree on page 41.
So that the OPC Alarm and Event Server can be used, events need to be defined, see
Features on page 25. The OPC Alarm and Event Server is normally used for alarm and
event lists, where the signal changes are displayed in text format.
1. Create a definition (e.g. breaker position) under AE Event Definitions. Once this has
been done, several signals may share the same definition. (Continue creating other
definitions in the same way.)
2. Attach the definition you created to a particular signal. This is done under the signal
object by giving the name of the AE Event Definition object (e.g. breaker position) as
a value of an AE Event Definition property.
In the tables below you can view examples of both single and double indications.
