Slot assignment in the module racks
The XIOC modules are plugged onto module racks that provide the
connection to the PLC. The modules are also interconnected
through the module rack.
The integrated bus system ensures interference-free transmission
between the individual slots on the bus. In addition, the bus
system supplies the individual modules with the voltage that is
required for internal signal processing.
The supply voltage for the I/O electronics is applied directly to the
corresponding I/O modules.
Four different module racks are available:

As a rule, the first module rack, which is used to take the CPU type
XC-CPU100/200, is a basic module rack. You can add on several
expansion module racks to the right side. The module racks must
be arranged so that one CPU module and a maximum of 7 XIOC
signal modules can be planned (a fig. 4).
