Chapter 5. FUNCTIONS

Cycle

Separate cycles can be set in CH1 and CH2 programs.

The cycle function allows you to repeat operation from segment 1 to the last segment in a program pattern the number of times set in the cycle count. A total of 10,000 times can be set.

When a cycle number of n is set, the total operation count is n + 1. During cycle operation, the operation at the last point in the final segment is not performed and executed values of program items (sequels to settings in the previous segment ; for example, PV event value, pid group number) that continue from a previous segment are cleared before program restart.

When the SP start point and end point are not equal, SP changes in a step-like manner during cycle operation.
