1. Select the object and variation type for a point range.
2. Specify the start point index and the number of points in

the range. Refer to the PM175 DNP3 Reference Guide for
available data points.

3. Repeat these steps for all point ranges you want to be

included into the Class 0 response.

Configuring DNP Event Classes

The PM175 can generate object change events for any static
analog input, binary input and binary counter point when a

corresponding point either exceeds a predefined threshold, or
the point status changes. A total of 64 change event points are
available for monitoring.

Object change events are normally polled via DNP Class 1,
Class 2 or Class 3 requests. You can link any change event
point to any event class upon the event priority. Refer to the
PM175 DNP3 Reference Guide for more information on polling
event classes via DNP.

A change event point index is normally the same as for the

corresponding static object point. If you wish to use
independent numeration for event points, enable re-mapping
event point indices via DNP Options setup (see above) so they
would start with index 0.

You should define a separate event setpoint for each static
object point you wish to be monitored for change events. To
view or change the factory-set DNP event setpoints, select
