Detailed Descriptions on Occupied I/O points
External Input
R0.0 to R0.15 .......................
Input
Operated as input.
It can be monitored as input even though counter
function is in use.
CHx IN-A, CHx IN-B ............
Counter Function
Input count signal of counting operation.
Count signal input is IN-A, IN-B.
There are three input modes: 1) Direction control
2) Individual input and 3) Phase input.
CHx Clear ............................
Counter Function
Input when counter current value is to be cleared.
Count current value is cleared to zero (0) with this
input.
CHx Mask ............................
Counter Function
Pause counter.
When this input turns on, counter is paused.
Internal input
R1.0 to R1.15 .......................
Input
This monitors signals from each function, such as
comparison output.
CMP0 to CMP7 ....................
Comparison Output Function
The comparison result of comparison output set
value in shared memory and counter current value
can be monitored by R1.0 to R1.7.
(Counter current value)
<
(Comparison output set
value)
→
Comparison output: OFF
(Counter current value)
≥
(Comparison output set
value)
→
Comparison output: ON
Comparison output ON/OFF can also be set as
reverse operation.
PLSx A, PLSx B
................
Pulse Output Function
Pulse signals from pulse output function can
be monitored with R1.8 to R1.15.
This input reflects pulse signals output to I/O
connector as internal input.
PWMx
................................
PWM output function
PWM signals from PWM output function can
be monitored with R1.12 to R1.15.
This input reflects PWM signals output to I/O
connector as internal input.
