The TM5 backplane of bus bases, which holds the individual I/O modules together, is auto-addressing. It is usually not necessary to set the address setting numbers.
However, in certain cases, it may be necessary to define specific slices or potential groups at fixed addresses, regardless of the preceding modules in the backplane. For this purpose, there are bus bases with rotary switches which allow you to set the address of an individual slice. The subsequent slices refer to this offset and are again automatically addressed from this point forward.
