In principle the layout of this example is similar to that of the previous example.
The difference lies in that 3 EXE are connected to each BNE and BNS using IOM, with each EXE connected to only one IOM.
An EXE into which 4 analog plug-in modules (S4A) are plugged requires 16 B channels for the S4A plug-in modules. Since one IOM connection has 8 x 2 B 
channels, a single IOM connection is sufficient here. Further IOM connections from the BNE/BNS can be taken from further EXE units.
No LAN operation is possible on the EXE.
In the upper diagram the maximum analog expansion is selected, and it is not permissible to mount other items.
It applies here that:
Since each plug-in mains unit can feed only a maximum of 2 modules, the combination BNE-EXE / BNS-EXE is now supplied using its own plug-in mains unit. 
Both the additional EXE units on the BNE and BNS have a single plug-in mains unit of their own. The Vout on the first EXE provides the power to the second 
EXE (Vin).
Only are where the connections of the EXE purely analog is a singleton IOM connection BND-EXE permissible.
 
Except where the connections of the EXE are purely analog2 IOM connections should always be made from the BND to the EXE.
