Processing details
• This instruction counts the number of times the device input specified by (s1) turns off  on only for the time (in 32-bit data
units) specified by (s2)  1ms and stores the operation result in the device specified by (d).

(1): The elapsed time is judged using the 1ms interrupt and the counted result is stored in (d)+1 and (d).
• The channel number of the high-speed counter specified by (s1) interlocks with the channel number in which parameters
are set.
• When a word device is specified by (s1), this instruction counts the number of pulses by the high-speed counter setting of
the channel number corresponding to each word device.
• When a bit device is specified by (s1), the following input assignment devices (shaded area) are valid.
• When the high-speed counter FX3 compatibility function is enabled, only the 1-phase 1-input pulse input mode (S/W)
(general-purpose input assignment of the 1-phase 1-input counter (switching S/W up or down)) is enabled.
