After installation
Assign slot numbers
After installation you can assign a slot number to each module, and this makes it easier to
assign the modules to the configuration table in
STEP 7 or in COM PROFIBUS. The
following table illustrates the assignment of the slots.

Unoccupied slots
If, in a configuration of an ET 200M with active bus modules, slots are unoccupied (e.g.
reserved for later use), then you must leave these slots free in the configuration in
STEP 7 or
COM PROFIBUS!
Attaching slot numbers
The following figure shows how you must attach the slot numbers. The slot number plates
are provided with the IM 153-x.
