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 ele-
ments that affect cycle time is, however, essential to effective programming and
PC operations.

PC operations.
The major factors in determining program timing are the cycle time and the I/O
response time. One run through all required CPU Unit operations is called a
cycle; the time required for each cycle is called the cycle time.
response time. One run through all required CPU Unit operations is called a
cycle; the time required for each cycle is called the cycle time.
The overall flow of the CPU Unit operation is as shown in the following flowchart.
