multiplying by a number larger than one. If you use 10 as a scaling factor, 11.4
Amps will be transmitted as 114. You must divide the value by 10 in the
master device to see the original value including one decimal place.
You can also use scaling to avoid overflowing the 16-bit maximum integer
value of 32767. If you have a value that can reach 157834, you cannot send it
by using DNP 16-bit analog object variations. Use a scaling factor of 0.1 so
that the maximum value reported is 15783. You must multiply the value by 10
in the master to see a value of 157830. You will lose some precision as the last
digit is rounded in the scaling process, but you can transmit the scaled value
by using standard DNP Objects 30 and 32.
Change the DNP analog input map with per point scaling and deadband by
entering
DNP AI <Enter>
. The “
;
” character is used as a scaling prefix, and
the “
:
” character is used as a deadband prefix. DNP counters are scaled
similarly. Per point scaling and deadband entries are not required.

Class Scaling and Deadbands
Class scaling (DECPLA, DECPLV, and DECPLM) and deadband (ANADBA,
ANADBV, and ANADBM) settings are applied to all indices that do not have
per point entries. For the class scaling settings, select 0 to multiply by 1, 1 for
10, 2 for 100, or 3 for a 1000.
Use the
DNP BO
command to change the binary output map.
DNP AO
, and
DNP BI
operate in a similar manner.

Change the DNP counter map with per point deadbands by entering
DNP C
<Enter>
. These settings are entered in a manner similar to entering analog
input settings.

that single phase elements are only available with a Form 9 meter.
