5.1 Special I/O Function Overview
The V200 PLCs support the special I/O functions as listed below:
Function name
Variable input filter constant
Function summary
Input filter constant (ON/OFF delay time) can be set by
user program. The setting range is 0 to 15 ms
(1 ms units). Default value is 0 ms. This function is
applied for X000 to X007 (8 points as a block).
Remarks
MW10 setting is
necessary to use this
function.
High
Speed
Counter
Single phase
up-counter Counts the number of pulses of single phase pulse
train. 2 channels of pulse input are available. The
countable pulse rate is up to 50 kHz for each channel.
Channel 1 ..... X000 count input, X002 reset input
Channel 2 ..... X001 count input, X003 reset input Only one among these 4
functions can be
selected.
MW10 is used to select
the function.
Single phase
speed counter Counts the number of pulses in a specified sampling
time. The sampling time setting is 10 to 1000 ms (10
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
bi-pulse counter
Counts the 2-phase pulses whose phases are shifted
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
available pulse rate is 50 Hz to 5 KHz (1Hz units)
Y0 ..... CW or Pulse (PLS)
Y1 ..... CCW or Direction (DIR)
Either one between
these 2 functions can
be used.
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
