Meaningful, if the sheets to be monitored by the various sensors have different sheet thicknesses.
Also suitable if the nominal thickness changes from cycle to cycle.
For this procedure the respective parameter set (program) must contain nominal thickness and
sensor number. The selection of the program is then performed by the PLC.
Disadvantage: Relative long time required for switching the program via the parallel interface.
