6. Function blocks6.1 Manufacturer function blocks6.1.7.10 ST - SET cycle timeGeneraleasyE4 base devices provide 32 SET cycle time function blocks,ST01 through ST32.This function block allows a SET cycle time to be defined.This cycle time is adjusted automatically if the maximum cycletime used in the program is less than this specified value.The maximum possible set cycle time is 1000 ms.The set cycle time cannot be implemented if the cycle time of theprogram is longer than it.The function block and its parametersFunction block inputsDescription Note(Bit)EN 1: Activates the function block.
