Applicable devices
*1 When a bit device is specified, specify one of X0 to X17.
Only X can be used for a bit device.
The nibble of a bit device cannot be specified.
*2 When a word device is specified, specify one of the channel numbers (CH1 to CH8).
When FX3 compatible function of a high-speed counter is valid, a channel number cannot be specified. Only X can be used for a bit
device.
If the channel numbers is specified in (s1), an error occurs.
Processing details
• This instruction counts the number of times the device input specified by (s1) turns off
on only for the time (in 16-bit data
units) specified by (s2)
1ms and stores the operation result in the device specified by (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.
General-purpose input assignment of the 1-phase 1-input counter (switching S/W up or down)
