12.1.5 FC 303 - FM_GET_SPEED - Calculate rotational speed consistent
With the FC 303 FM_GET_SPEED, you can calculate the rotational speed of the input
signals of both channels of the System SLIO frequency measurement module. By this
function internally SFC 14 - DPRD_DAT for consistent reading of user data is called.
Here, the error messages of the function block are returned by ERROR.
