If no further event summaries are available, attempting to load the next event will cause the event
type analog (point 105) 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 2 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 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 114 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.
If the DNP command is issued without parameters, the relay displays both the analog and binary
maps, which have the following format:
==>DNP<STX>
Analogs = 112 28 17 35 1 56 57 58 59 60 61 62 63 64 65 \
66 67 100 101 102 103
Binaries = Default Map<ETX>
==>
If the DNP command is issued with an S parameter, the relay displays only the analog map;
likewise, a T causes the relay to display only the binary map. If the map checksum is determined
to be invalid, the map will be reported as corrupted during a display command, as follows:
==>DNP T<STX>
Binaries = Map Corrupted<ETX>
==>
If the map is determined to be corrupted, DNP will respond to all master data requests with an
unknown point error. If the DNP command is issued with an A or B parameter at level 2 or
greater, the relay requests the user enter indices for the corresponding list, where a parameter of
A specifies the Analog list and B specifies the Binary list. The relay accepts lines of indices
until a line without a final continuation character (\) is entered. Each line of input is constrained
to 80 characters, but all the points may be re-mapped, using multiple lines with continuation
characters ( \ ) at the end of the intermediate lines. If a single blank line is entered as the first
line, the re-mapping is disabled for that type (i.e., the relay uses the default analog or binary
map). For example, the first example remap could be produced with the following commands:
==>DNP A
Enter the new DNP Analog map
