5.135 L_SdRuntimeComp - runtime compensation
This FB is used for the runtime compensation of position signals that are, for instance, transmitted
by means of a bus system.
• The output signal leads the input signal by the last position difference.
• The resulting rate time equals the task runtime of the program in which the FB is used.
