The operation mode can be set in the parameter setting. For details, refer to the following.
Counter function selection
This function executes the counter function selection using both the
program and CH
Function input terminal (FUNC1, FUNC2) of the
connector for external devices, or using either of them.
Normal
mode
Count disable function
This function stops counting pulses while CH
Count enable
command (RY24, RY3C) is on.
Latch counter function
This function acquires the count value and stores it in the remote
register.
Sampling counter function
This function counts pulses that are input during the preset
sampling period.
Periodic pulse counter function
This function stores the present value and difference value to the
corresponding remote registers by the preset cycle time.
Count disable/preset/replace
function
According to the status change of CH
Function input terminal
(FUNC1, FUNC2) of the connector for external devices, this
function executes the count disable function and preset/replace
function without switching the functions.
Latch counter/preset/replace
function
According to the status change of CH
Function input terminal
(FUNC1, FUNC2) of the connector for external devices, this
function executes the latch counter function and preset/replace
function without switching the functions.
Frequency measurement function
This function counts the pulses of the pulse input terminals in
phase A and B, and automatically calculates the frequency.
Frequency

nt mode
Rotation speed measurement function
This function counts the pulses of the pulse input terminals in
phase A and B, and automatically calculates the rotation speed.

nt mode
Pulse measurement function
This function measures CH
Function input terminal (FUNC1,
FUNC2) or CH
Latch counter input terminal (LATCH1, LATCH2)
of the connector for external devices, and calculates the ON width.

nt mode
PWM output function
This function outputs the specified PWM waveform from any
coincidence output 1 to 4 terminals (EQU1 to EQU4).
PWM output
mode
Output HOLD/CLEAR setting function
This function sets the output status of the extension output module
(Y0 to YF) used as the output of Coincidence output (EQU1 to
EQU4) and the cam switch function to HOLD or CLEAR.
Common to
all modes
Cyclic data update watch function
This function monitors the cyclic data update interval. When the
cyclic transmission remains to be stopped over the set watch time,
this function holds or clears the value which is output just before.
Error notification function
When a moderate error or a major error occurs in the high-speed
counter module, this function notifies the master station of the error
using the remote register and the remote input signal.
Function at the extension module
installation
One extension I/O module can be connected to one high-speed
counter module.
The cam switch function can be used by connecting the extension
I/O module. In addition, functions unique to the extension I/O
module can be used.
CC-Link IE Field Network diagnostic
function
With this function, whether any network error occurs or not can be
checked through GX Works2 connected to the CPU module.
