11.2.5. COMMAND to read all the CVMk parameters
COMMAND CONCEPT QUESTION ANSWER SIZE
RAL
Read TOTAL
$pp RAL ch
$pp + 244 bytes + ch
With this parameter all the parameters are requested: 30 x 8 bytes in hexa-ASCII
format in the following order:
[ 0 ] L12 [ 1 ] L23 [ 2 ] L31 [ 3 ] Av Voltage phase-phase
[ 4 ] L1 [ 5 ] L2 [ 6 ] L3 [ 7 ] Av Voltage phase-neutral
[ 8 ] L1 [ 9 ] L2 [ 10 ] L3 [ 11 ] Av Current
[ 12 ] L1 [ 13 ] L2 [ 14 ] L3 [ 15 ] III Active power
[ 16 ] L1 [ 17 ] L2 [ 18 ] L3 [ 19 ] III Inductive power
[ 20 ] L1 [ 21 ] L2 [ 22 ] L3 [ 23 ] III Capacitive power
[ 24 ] L1 [ 25 ] L2 [ 26 ] L3 [ 27 ] Av Power factor
[ 28 ] Frequency
[ 29 ] III Apparent power
- 2 bytes : current units 00 - mA / 01 - A
- 2 bytes : power units 00 - W / 01 - kW
(*) - Power factor ( x 100 ) : When is capacitive it adds 200
0 ---------------------------- 100 --------------------------- 200
