The Status field is used exactly as defined. All other fields are ignored. A pulse operation
asserts a point for a single processing interval. Caution should be exercised with multiple remote
bit pulses in a single message (i.e., point count > 1), as this may result in some of the pulse
commands being ignored and returning an already active status.
Analog Outputs (objects 40 and 41) are supported as defined by the preceding table. Flags
returned with object 40 responses are always set to 0. The Control Status field of object 41
requests is ignored. If the value written to index 0 is outside of the range 1 through 6, the relay
will not accept the value and will return a hardware error status.
Relay Summary Event Data
Whenever there is unread relay event summary data (fault data), binary input point 1023 will be
set. In order to load the next available relay event summary, the master should pulse binary
output point 23. This will cause the event summary analogs (points 103–111) to be loaded with
information from the next oldest relay event summary. Since the summary data is stored in a
first-in, first-out manner, loading the next event will cause the data from the previous load to be
discarded. The event summary analogs will retain this information until the next event is loaded.
If no further event summaries are available, attempting to load the next event will cause the event
type analog (point 103) to be set to 0.

EMAPPING
The analog and binary input points (objects 1, 2, 30, and 32) may be remapped via the DNP
command. The map is composed of two lists of indices, one for the analogs (30 and 32) and the
other for the binaries (1 and 2). The indices correspond to those given by the relay’s default
DNP data map. The order in which they occur in the list determines the index that the
corresponding value is reported as to the DNP master. If a value is not in the list, it is not
available to the DNP master. All 1025 binaries and 112 analogs may be included in the list, but
may occur only once. The maps are stored in nonvolatile memory. The
DNP command is only
available if DNP has been selected on one of the ports. The DNP command has the following
format:
DNP [type]
where type may be A, B, S, T, or omitted.
