Cycle Time
To aid in PC operation, the average, maximum, and minimum cycle times
can be displayed on the Programming Console or any other Programming
Device and the maximum cycle time and current cycle time values are held in
AR 26 and AR 27. Understanding the operations that occur during the cycle
and the elements that affect cycle time is, however, essential to effective pro-
gramming and PC operations.
The major factors in determining program timing are the cycle time and the
I/O response time. One scan of CPU operation is called a cycle; the time
required for one cycle is called the cycle time. The time required to produce a
control output signal following reception of an input signal is called the I/O
response time.
The operation of the CPU11-E is different from that of the CPU01-E and
03-E. The overall flow of the CPU01-E and 03-E operation and CPU11-E
operation are as shown in the following flowcharts.
