@INI
880
P: Port specifier
C: Control data
NV: 1st word with

INI(880) is used to start and stop target value comparison, to
change the present value (PV) of a high-speed counter, to
change the PV of an interrupt input (counter mode), to change
the PV of a pulse output, or to stop pulse output.

PRV(881) is used to read the present value (PV) of a high-
speed counter, pulse output, or interrupt input (counter mode).

lution
D: 1st destination
word
Reads the pulse frequency input from a high-speed counter and either
converts the frequency to a rotational speed (number of revolutions) or
converts the counter PV to the total number of revolutions. The result is
output to the destination words as 8-digit hexadecimal. Pulses can be
input from high-speed counter 0 only.
