Light curtain design
Applications like height measurement require information regarding individual beam status as well as the exact
beam positions. This is only possible if the light curtain itself is clearly defined. This chapter defines the light
curtain and reference beams and also describes specific measurement modes.
The controller ObjectC 100 offers many functions to obtain information from the Object100 light curtain. The
following light curtain functions are described in the given chapters:
•
Standard and reverse beam counting mode:
•
Blanked beams:
