Precautions for Correct Use Precautions for Correct Use
When more than one comparison condition is met in a cycle, the first interrupt task in the table
will be executed in that cycle. The next interrupt task in the table will be executed in the next
cycle.
Additional Information
The range comparison table can be used without starting an interrupt task when the comparison
condition is met. The range comparison function can be useful when you just want to know
whether or not the high-speed counter PV is within a particular range.
Use the Range Comparison Condition Met Flags to determine whether the high-speed counter
PV is within a registered range.
The CTBL instruction compares the PV of a high-speed counter (0 to 5) to target values or ranges and
executes the corresponding interrupt task (0 to 15) when the specified condition is met.
