Touchprobe function – length measurement

This function can be used to determine the length of bulk material. For this purpose, the corresponding sensor, for example a light barrier, is connected to Touchprobe input DI 04. If the length measurement function is activated, the length is determined between two rising edges of the TP input and is output on the process data words "Touchprobe 1 - Detected value". The length measurement is performed in application mode 200 (speed control).

Make the following settings for length measurement:
