3. Create the program for interrupt task 12. Always put an END(001) instruc-
tion at the program's last address.
4. Use CTBL(882) to start the comparison operation with high-speed counter
1 and interrupt task 12.
W0.00
@CTBL(882)
5. Operation
When execution condition W0.00 goes ON, the comparison starts with
high-speed counter 1.
When the PV of high speed counter 1 is between 25,000 and 25,500, cyclic
task processing is interrupted, and interrupt task 12 is processed. When
interrupt task 12 processing is completed, processing of the interrupted cy-
clic task resumes.

Function
Range 1 interrupt task number = 12 (C hex)
Range 2 lower and upper limit values
(Not used and don't need to be set.)
Disables range 2.
~
Set the fifth word for ranges 3 to 7 (listed at left) to #FFFF to
disable those ranges.
~
Range 8 lower and upper limit values
(Not used and don't need to be set.)
Disables range 8.
Use high-speed counter 1.
#0001
Register a range comparison table and start
#0001
comparison operation.
