1 Overview
Operation Example
Where,
• Execution interval: 100 milliseconds
• Input refresh: 1 millisecond
• I/O control: 10 milliseconds
• Output refresh: 1 millisecond
The execution time of the Cyclic Script is 1 + 10 + 1 = 12 milliseconds, so the script executes normally.
The input delay can be from 5 to 105 milliseconds, and the output delay can be from 1 to 101 milliseconds.
Since the sleep time is 100 - 12 = 88 milliseconds, display processing is executed every 88 milliseconds for each scan.
