10.5.1 Assignment of switch positions to the PLC inputs
The tables below give the assignment of the switch positions of S1 and S2 to PLC inputs
I160 to I175.
The two switches operate with a 0 V logic, e.g. if switch S1 is in position 3 then input I162 is logic 0
and inputs I160, I161 and I163 to I167 are logic 1.
