Memory Requirement of the Set Cycle Time Function Block

The set cycle time function block requires 24 bytes of memory plus 4 bytes per

constant on the function block input.

Function of the Set Cycle Time Function Block

The function block is used to define a fixed cycle time.

Actual cycle time is less than the set cycle time:

If the maximum cycle time present is less than the set cycle time, the set cycle

time is constant.

Actual cycle time is greater than the set cycle time:

If the maximum cycle time present is greater than the set cycle time, the set

cycle time has no effect.

IMPORTANT

The function block must be enabled so that it can work.

Coil ST01EN is active. If coil ST01EN is not active, the

entire function block is deactivated and reset.
