Count for W pulses in time window defined by the CPD
command. Demo Code revision 3.05 only.

14.1 (6511)
15.1 (6513)

Absolute count for VAR pulses. Reset with CPC command.
Demo Code revision 3.05 only.

14.2 (6511)
15.2 (6513)

Count for W pulses in time window defined by the CPD
command. Demo Code revision 3.05 only.

Example:

M3.1

Displays Wh total consumption of phase A.

Displays for total consumption wrap around at 999.999kWh (or kVARh, kVAh) due to the number of
available display digits. Internal registers (counters) of the Demo Code are 64 bits wide and do not wrap
around.

Values for [phase]: 0 = sum, 1 = A, 2 = B, 3 = C (6513), 0 = sum, 1 = A, 2 = B (6511)
