z Execution of CTBL and INI Instructions for Cyclic Task
Execute the instructions in the following order.
Refer to 11-3-2 Present Value Comparison for details.
The comparison of the high-speed counter PV has the following two ways: Target Value Comparison
and Range Comparison.
The specified interrupt task is executed when the high-speed counter PV matches a target value regis-
tered in the table.
• The comparison conditions (target values and counting directions) are registered in the comparison
table along with the corresponding interrupt task number. The specified interrupt task will be exe-
cuted when the high-speed counter PV matches the registered target value.
• Comparison is executed in the order set in the comparison table. Once comparison has cycled
through the comparison table, it will return and wait for a match with the first target value again.
The following examples show the operation of an interrupt task for a comparison table.
Example 1
Register the comparison table with the CTBL (COMPARISON
TABLE LOAD) instruction. Specify the interrupt tasks to be
started in this step.
Start comparison with the CTBL (COMPARISON TABLE
LOAD) or INI (MODE CONTROL) instruction. Here, high-
speed counter interrupts will be valid.
Stop with the INI (MODE CONTROL) instruction.
