INI(880) is used to start and stop target value comparison, to
INI
change the present value (PV) of a high-speed counter, to
change the PV of an interrupt input (counter mode), to change
P
the PV of a pulse output, or to stop pulse output.
C
NV
PRV(881) is used to read the present value (PV) of a high-
PRV
speed counter, pulse output, or interrupt input (counter mode).
P
C
D
Reads the pulse frequency input from a high-speed counter and either
PRV2
converts the frequency to a rotational speed (number of revolutions) or
converts the counter PV to the total number of revolutions. The result is
C1
output to the destination words as 8-digit hexadecimal. Pulses can be
input from high-speed counter 0 only.
C2
D
CTBL(882) is used to perform target value or range comparisons for
CTBL
the present value (PV) of a high-speed counter.

SPED(885) is used to specify the frequency and perform pulse output
