Method for adjusting the clock frequency of a microprocessor of an industrial automation component and automation component with a microprocessor with adjustable clock frequency

摘要

The method involves detecting a required time period (LZ) for executing a main program cycle of a control program running on an automation component. The time period is compared with a maximum value (PD). A clock frequency (T) is determined on the basis of the comparison result and is utilized for a microprocessor (CPU).
