Computing the Cycle Time
Section 2-7
2-7-4 I/O Refresh Times for PLC Units
CP-series Expansion Unit and Expansion I/O Unit I/O Refresh Times
Note The I/O refresh time for CPU Unit built-in I/O is included in overhead process-
ing.
2-7-5 Cycle Time Calculation Example
The following example shows the method used to calculate the cycle time
when CP-series Expansion I/O Units only are connected to a CP1L CPU Unit.
