Maximum Cycle Time (Watch Cycle Time)

208
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 refreshing methods
• Disabling Special I/O Unit cyclic refreshing
A minimum (or fixed) cycle time can be set in CS/CJ-series PCs. Variations in
I/O response times can be eliminated by repeating the program with a fixed
cycle time.
The minimum cycle time (1 to 32,000 ms) is specified in the PC 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.
