11-3-3 High-speed Counter Interrupt Instruction
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.
 Contents of the Comparison Table
• Target-value Comparison Table
Depending on the number of target values in the table, the target-value comparison table requires
a continuous block of 4 to 19 words.
