CPU MODULE 4.
The interrupt counters in C224 to C255 are allocated to the interrupt pointers I0 to I31 as
shown below, and count the occurrences of interrupts by those of I0 to I31.
(d) The counter-use points can be set arbitrarily by 16 points using the serial
numbers.
By setting the counter which points to the number actually used, the counter
processing time subsequent to the END instruction can be shortened.
(e) The counter set values are as follows:
Interrupt

C0 to C255 :constant or word device (D)
C256 to C1023 :word device (D, W, R)
(Allocate a storage device for the set value by setting
parameters.)
POINT
When the timer-use points are set to 257 points or more or the counter-use points
are set to 257 points or more, the set value storage devices (D, W, R) specified at
the time of timer/counter use point setup are automatically set in the serial
numbers.
<Example>
When the timer-use points are set to 512 points and the set value storage device
is set to D1000, D equivalent to 256 points (D1000 to D1255) in T256 to T511
becomes the devices for the set values using the continuous numbers.
