L_Odometer_1

This FB is used to detect positions and calculate distances.

• Depending on the input selection set in

C01022

, a position signal can be detected at the

dnInPosition_p input or a speed can be detected at the nInSpeed_v input.

• The position is detected/accepted via the edge selected in

C01023

at the bTriggerPulse input.

• If "Ring buffer" is selected in

C01021

, the measurement will start all over again after the number

of measurements selected in

C01020

has been performed and the old values will be

overwritten. Otherwise, the measurement will stop.
