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