the fault record (D0.FLTMSTA) which change are also entered in the DNP AI event
buffer. They are also timestamped, but the official time of the fault is the event
timestamp on the LD0.FLTMSTA1.OpCnt.stVal point.
Fault information, including timestamps, is retrieved from the IED by a DNP master
using a Class1_Class2_Class3 scan or an integrity (Class1_Class2_Class3_Class0)
scan. The AI event default variation should be set to include time stamps. It is possible
that not all points of the fault generate events. This happens when the point of the
new fault has the same value as the previous fault.

DNP points

Point configuration

The DNP 3.0 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 so wanted. Point gaps cannot be read by the client.

Class assignment

Class assignment allows the events generated in the IED to be reported as DNP 3.0
events.
There are several possible configurations. 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
