This object transmits the setpoint of the sample time. The setpoint is evaluated for the setting of the
sample time of all four A/D-channels. The smaller the output data rate is chosen, the higher is the
resolution of the measured values reached.
Assignment of the variable Sample_Time_Set_Point:
The setpoint of the sample time can be set in 0.5
