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 map). If a single entry of OFF or NA is entered, all objects of that type will be
disabled. For example, the first example re-map could be produced with the following
commands:
==>DNP AI<ENTER>
Enter the new DNP Analog Input map
112 28 17 \<ENTER>
35 1 56 57 58 59 60 61 62 63 64 65 66 67 100 101 102 \<ENTER>
103<ENTER>
Save Settings (Y/N)? Y<ENTER>
==>DNP BI<ENTER>
Enter the new DNP Binary Input map
<ENTER>
Save Settings (Y/N)? Y<ENTER>
==>DNP AO<ENTER>
Enter the new DNP Analog Output map
OFF<ENTER>
Save Settings (Y/N)? Y<ENTER>
==>
The DNP command will report an error if an index is used twice, an invalid index is used, or
nonnumeric data is entered:
xx is referenced more than once, changes not saved
xx is not a valid index, changes not saved
Invalid format, changes not saved
In addition to re-mapping, these commands can be used on analog inputs to create custom
scaling and dead bands per point. Scaling is done by adding a semicolon and scaling factor to a
point reference. The base value will be multiplied by the scaling factor before reporting it. This
is done instead of the DECPLA setting that would normally apply. Dead bands are added using
a colon and dead-band count. This dead band will override the ANADBA setting. For example:
==>DNP AI<ENTER>
Enter the new DNP Analog Input map
112;5 28;0.2 17:10 1;1:15<ENTER>
==>
These settings will cause the value at index 112 (now at index 0) to be multiplied by five before
it is reported. Similarly, the value at index 28 (now at index 1) will be multiplied by 0.2 before it
is reported. Both of these values will use the default dead band. The value at index 17 (now at
index 2) is left for default scaling, but uses a dead band of ±10 counts. Similarly, the value that
was at index 1 (now at index 3) is now scaled by 1 and uses a dead band of ±15 counts.
