s = display secondary volts (1=yes, 0=no) 1
753D - 753D 30014 - 30014 DNP Options UINT16 bit-mapped
-------- ww-i-vvp
p selects primary or secondary values for DNP voltage,
current and power registers
(0=secondary, 1=primary)
vv sets divisor for voltage scaling
(0=1, 1=10, 2=100)
i sets divisor for current scaling
(0=1, 1=10)
ww sets divisor for power scaling in addition to scaling
for Kilo
(0=1, 1=10, 2=100, 3=1000)
Example:
120KV, 500A, 180MW
p=1, vv=2, i=0, and ww=3
voltage reads 1200, current reads 500, watts reads 180

vv = number of digits after decimal point for voltage
display.
0 - For voltage range (0 - 9999V)
1 - For voltage range (100.0kV - 999.9 kV)
2 - For voltage range (10.00kV - 99.99 kV)
3 - For voltage range ( 0kV - 9.999 kV)
This setting is used only when k=1.
k = enable fixed scale for voltage display.
(0=autoscale, 1=unit if vv=0 and kV if vv=1,2,3 )
g = enable alternate full scale bar graph current
(1=on, 0=off)
e = enable ct pt compensation
(0=Disabled, 1=Enabled).
i = fixed scale and format current display
0=normal autoscaled current display
1=always show amps with no decimal places
nn = number of phases for voltage & current screen
(3=ABC, 2=AB, 1=A, 0=ABC)
s = scroll (1=on, 0=off)
r = password for reset in use (1=on, 0=off)
p = password for configuration in use (1=on, 0=off)
d = daylight saving time changes (0=off, 1=on)
y = diagnostic events in system log (1=yes, 0=no)
w = power direction
(0=view as load, 1=view as generator)
f = flip power factor sign (1=yes, 0=no)

replaces CT numerator in the full scale current
calculation. (See Note 12)
