Every device, e.g., remote I/O that can be reached in a network must be assigned a unique 
SRS. 
 
 
3.3.2  Permissible Slot Assignments 
The slot assignment is defined as follows: 
1.  Slot 1 and slot 2 on each base plate are reserved for system bus modules.  
Do not insert any other module into these slots! 
2.  Only slots complying with the rules specified in the next section are permitted for 
processor modules. 
3.  Once the slots for the processor modules are determined, I/O and communication 
modules may be inserted into all remaining slots. 
Slots Permitted for Processor Modules 
The following rules must be observed when assigning the slots to the processor modules, 
also in the Hardware Editor: 
1.  A maximum of four processor modules may be used. 
2.  Processor modules may only be inserted in the following slots: 
-  Slots 3 to 6 on rack 0. 
-  Slots 3 to 4 on rack 1. 
3.  Slot 5 on rack 0 and slot 4 on rack 1 may not simultaneously contain processor 
modules. 
4.  Slot 6 on rack 0 and slot 3 on rack 1 may not simultaneously contain processor 
modules. 
 
NOTE 
 
System malfunction possible! 
Only slots complying with these rules may be used for processor modules.

Mono operation:The project is configured in SILworX for mono operation and has only 
one processor module in slot 3, at least one system bus module in slot 1, I/O modules 
and possibly communication modules. The switch for mono start-up must be set within 
SILworX. It is always possible (and recommended!) to configure the system bus mod-
ules redundantly!
