What are the DNP3 Class and Event? Why are they used?
Data on a DNP3 outstation is assigned a Class. A DNP3 master station is able to poll for the data in each class independently of other classes.
A Class 1, Class 2, or Class 3 Poll causes an outstation to return event data for the points that are assigned those particular Class(es). Use the Class Polling section on the Outstation.
