For a detailed configuration example see chapter 11.3.
Figure 5.6: Hole recognition
 For hole recognition within a web material, a beam area must be defined over the area to be monitored
and mapped to an output. All beams in this area are interrupted. If a beam becomes "free" due to a flaw
in the material, the output switches.
 If, for example, the web edge wanders slightly, the beam area can be dynamically adapted by "tracking"
the start beam by selecting the
