This element is used to measure the distance to dynamics. This sensor detects just dynamics.
The distance is reported to a word within the PLC in the units chosen by you on the edit mask (default are 1 imp/mm). In the field ‘points’ you have to specify how many points on its length the sensor checks to find a dynamic at all. Please adjust this value to the size of your dynamics. If it is too low, it is possible that the sensor ignores a piece. If it is too high, the sensor consumes more CPU power than necessary.
With the check box ‘max value if nothing found’ you can adjust whether the sensor shall report a ‘0’or the maximum value to the PLC if it does not find a dynamic at all.
To change the orientation of a distance sensor you have to point with the mouse cursor near to the end of it and wait until the mouse cursor changes to a cross.
If you only need a contact that switches at a special distance, just program in OB2 for example:
