Introduction
The DNP command is available to view and remap the DNP data. This command is available at
level 1 for viewing data, but only from level 2 can it be used to remap the DNP map.
Inputs
Command Syntax: DNP [A|B|S|T]
DNP [AI|AO|BI|BO|C] [VIEW]
The DNP analog input, analog output, counter, binary output, and binary input points may be
remapped via the
DNP command. The map is composed of five lists of indices: one for the
analog inputs (30 and 32), one for the binary inputs (1 and 2), one for the binary outputs (10 and
12), one for the analog outputs (40 and 41), and the other for the counters (20 and 22). The
indices correspond to those given by the relay’s DNP data map. The order in which they occur in
the list determines the index that the corresponding value is reported to the DNP master. If a
value is not in the list, it is not available to the DNP master. All points of the corresponding type
may be included in the list, but must only occur once. The maps are stored in nonvolatile
memory and are protected with a checksum. The
DNP command is only available if DNP has
been selected on one of the ports.
If the DNP command is issued without parameters, the relay displays all of the maps with the
following format:
=>DNP<ENTER>
Binary Inputs = Default Map
Binary Outputs = Default Map
Counters = Default Map
Analog Inputs = 112 28 17 35 1 56 57 58 59 60 61 62 63 64 65 \
66 67 100 101 102 103
Analog Outputs = Off
=>
If the DNP command is issued with an object type specified (AI, AO, BI, BO, C) and the VIEW
parameter, the relay displays only the corresponding map. The S parameter is equivalent to
AI VIEW and the T parameter is equivalent to BI VIEW; they are available for consistency with
the older products. If the map checksum is determined to be invalid, the map will be reported as
corrupted during a display command, as follows:
=>DNP BI VIEW<ENTER>
Binary Inputs = Map Corrupted
=>
If the DNP command is issued with just an object type specifier (AI, AO, BI, BO, C) at level 2
or greater, the relay asks the user to enter indices for the corresponding list. (The A parameter is
the same as AI and B is the same as BI; these parameters are available for consistency with older
products.) 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 remapped,
