C1: Control Data
The function of PRV2(883) is determined by the control data, C1.
Note
The second digit of C (
@
) specifies the units and the third digit (
*
) specifies
the frequency calculation method.
C2: Pulses per Revolution
Specifies the number of pulses per revolution (0001 to FFFF hex).
D: First Destination Word
The PV is output to D or to D and D+1.
