Interrupt Functions
Section 6-1
4.
Use CTBL(882) to start the comparison operation with high-speed counter
0 and interrupt task 10.
5.
Operation
When execution condition W0.00 goes ON, the comparison starts with
high-speed counter 0.
When the PV of high speed counter 0 reaches 30,000, cyclic task process-
ing is interrupted, and interrupt task 10 is processed. When interrupt task
10 processing is completed, processing of the interrupted cyclic task re-
sumes.
Example 2: High-speed
Counter (Ring Mode)
In this example, high-speed counter 1 operates in circular (ring) mode and
starts interrupt task 12 when the PV is between 25,000 (0000 61A8 hex) and
25,500 (0000 639C hex).
The maximum ring count is set at 50,000 (0000 C350 hex).

1.
Set high-speed counter 1 in the PLC Setup’s Built-in Input Tab.
2.
Set the range comparison table starting at word D20000. Even though
range 1 is the only range being used, all 40 words must still be dedicated
to the range comparison table.
