Arrangement of the Modules in an ET 200M Configuration
Rules
The following rules apply to the arrangement of the modules in an ET 200M:
An ET 200M can only be installed on one mounting rack (rail), because coupling
to other mounting racks via interface modules is not permissible.
A maximum of 8 signal modules, function modules or communication
processors can be installed to the right of the IM 153-x.
Figure 4-3 shows the arrangement of the modules in an ET 200M configuration
with eight S7-300 modules.
