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.
The number of event setpoints for each static object type is specified via the
DNP Options setup (see above). Notice that the device clears all event
buffers and links the default set of static points to each event object type
every time you change the number of points for any of the objects.
To define setpoints for selected static points:
1. Check the “Ext” box if you wish to use the extended point
list.
2. Select a parameter group and then a desired parameter
for each event point.
3. For AI and BC points, select a relation and an operating
threshold or a deadband to be used for detecting events.
All thresholds are specified in primary units. The following
relations are available:
Delta – a new event is generated when the absolute
value of the difference between the last
reported point value and its current value
exceeds the specified deadband value;
More than (over) - a new event is generated when the
point value rises over the specified threshold,
and then when it returns below the threshold
minus a predefined return hysteresis –
applicable for AI objects;
Less than (under) - a new event is generated when
the point value drops below the specified
threshold, and then when it returns above the
threshold plus a predefined return hysteresis –
applicable for AI objects.
