Minimum Cycle Time

The following functions are described in this section
• Minimum cycle time function
• Maximum cycle time function (watch cycle time)
• Cycle time monitoring
• Quick-response inputs
• Interrupt functions
• I/O refresh method
• Data background processing
A minimum (or fixed) cycle time can be set in CS/CJ-series PLCs. (See note.)
Variations in I/O response times can be eliminated by repeating the program
with a fixed cycle time.
Note Indicates the cycle time for program execution when using a parallel
processing mode.
The minimum cycle time (1 to 32,000 ms) is specified in the PLC Setup in1-
ms units.
Minimum cycle time
(Effective)
Actual cycle time
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.
