Memory requirement of the 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.
h
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.
