System description
Method a) sequentially by program switching
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.
The following is a typical application example
PLC
1. select Prog.1
2. measure Pr.1
3. evaluate result Pr.1
4. select Prog.2
5. measure Pr.2
6. evaluate result Pr.2
7. select Prog.3
8. measure Pr.3
9. evaluate result Pr.3
