PowerSmart+ Advanced Power Quality Meter 101
The factory-set Class 0 point ranges are shown in the picture below. To change the
factory settings and build your own Class 0 response message:
Select the object and variation type for a point range.
Specify the start point index and the number of points in the range. Refer to the
PowerSmart+ Advanced PQM DNP3 Reference Guide for available data points.
Repeat these steps for all point ranges you want to be included into the Class 0 response.

Configuring DNP Event Classes
The PowerSmart+ Advanced PQM 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
PowerSmart+ Advanced PQM 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 Protocol Setup from the Meter Setup menu and click on the DNP Event Setpoints
tab.
