Configuring DNP Event Classes
The EM920 generates 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
EM920 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. To use independent
numeration for event points, enable re-mapping event point
indices via DNP Options setup (see above) so they start with
index 0.
Define a separate event setpoint for each static object point
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.
