The control algorithms are based on scan values where the time interval between two consecutive scans should be taken into account. The function blocks calculate the value of this interval automatically, which means they can be placed anywhere in the section without having to take the time management into consideration.

For example, the SAMPLETM function block can be used, which should be attached to the input EN of the function block to be scanned.

If the scan interval of the servo-loop exceeds 1 second, the function block MS: Manual control of an output should be switched to the function blocks PIDFF: Complete PID controller and PI_B: Simple PI controller so that the servo-loops can be controlled manually independently of the scan interval.
