Cycle Time Overview
Note
The cycle time depends on the following conditions.
1. The cycle time is not affected by the number of tasks that are used in the
2. When the mode is switched from MONITOR mode to RUN mode, the cycle
Cycle time = (1) + (2) + (3) + (4) + (5)
1: Overseeing
2: Program Execution
3: Cycle Time Calculation
Checks the I/O bus and user program
memory, checks for battery errors and
refreshes the clock.
Executes the user program, and calcu-
lates the total time taken for the instruc-
tions to execute the program.
Waits for the specified cycle time to
elapse when a minimum (fixed) cycle time
has been set in the PLC Setup.
Calculates the cycle time.

Total instruction execution time
When the cycle time is not fixed, the time
for step 3 is approximately 0.
When the cycle time is fixed, the time for
step 3 is the preset fixed cycle time minus
the actual cycle time ((1) + (2) + (4) + (5)).
