5.1 Special I/O Function overview
The FlexiLogics PLCs support the special I/O functions as listed below:
Function name Function summary Remarks
Variable input filter constant Input filter constant (ON/OFF delay time) can be set by MW10 setting is
user program. The setting range is 0 to 15 ms necessary to use this
(1 ms units). Default value is 0 ms. This function is function.

Channel 1 ..... X000 count input, X002 reset input MW10 is used to select
Channel 2 ..... X001 count input, X003 reset input the function.

Speed speedcounter time. The sampling time setting is 10 to 1000 ms (10
Counter ms units). 2 channels of pulse input are available. The
countable pulse rate is up to 50 kHz for each channel.
Channel 1 ..... X000 count input
Channel 2 ..... X001 count input
Quadrature Counts the 2-phase pulses whose phases are shifted
bi-pulse counter 90° each other. Counts up when phase A precedes,
and counts down when phase B precedes. The
countable pulse rate is up to 5 kHz.
Phase A ..... X000
Phase B ..... X001
Reset ......... X002
Interrupt input function Immediately activates the corresponding I/O interrupt
program when the interrupt input is changed from OFF
to ON (or ON to OFF). 2 points of interrupt input are
available.
X001 ..... Interrupt 1 (I/O interrupt program #1)
X002 ..... Interrupt 2 (I/O interrupt program #2)
Pulse output function Variable frequency pulse train can be output. The Either one between
available pulse rate is 50 Hz to 5 KHz (1Hz units) these 2 functions can
Y0 ..... CW or Pulse (PLS) be used.
Y1 ..... CCW or Direction (DIR) MW11 is used to select
the function.
PWM output function Variable duty cycle pulse train can be output. The
available ON duty setting is 0 to 100 % (1 % units).
Y0 ..... PWM output
