10-2-1 Minimum Cycle Time
10-2 Cycle Time/High-speed Processing
A minimum (or fixed) cycle time can be set in PLCs. Variations in I/O response times can be eliminated
by repeating the program with a fixed cycle time.
The minimum cycle time (0.1 to 32,000 ms) is specified in the PLC Setup in 0.1-ms units.
If the actual cycle time is longer than the minimum cycle time, the minimum cycle time function will be
ineffective and the cycle time will vary from cycle to cycle.

When using the CX-Programmer, make the settings on the Timings/Synchronous Tab Page.
