DNP points
Point configuration
The DNP3 point map is configurable in PCM600. All points in the IED are
unmapped as default. In PCM600, the unmapped points in the variables list on the
left may be inserted to the active point list on the right.
Point gaps may be inserted if wanted. Point gaps cannot be read by the client.
Class assignment
Class assignment allows the events generated in the IED to be reported as DNP3
events. Some configurations exceed the class assignment possibilities defined by
the standard.

BOS points exist only if the corresponding CROB point has been inserted in the
active point list.
Class assignment cannot be performed on CROBs. They can only be performed on
the corresponding BOS points in a limited fashion; they may only be assigned
Class 0 or None and only affect the class 0 scan. This means they cannot be
configured to generate events. The BOS points, however, have been made available
as BI points, which can be configured to generate events.
