1 Layout of the XC100
The XC-CPU101-... controllers – referred to below simply as
XC100 – have been designed for application in machinery and
plant control systems. These controllers are fitted with interfaces
for connecting to a programming device (RS 232) and for linking
to decentralized CANopen expansion units, so they can form the
core of a comprehensive automation system.
The XC100 controller has a compact design and can be fitted with
either local or decentralized expansion. The basic unit consists of:
• Module rack
• A CPU for control or visualisation, with integral power supply
and local inputs/outputs.
• XIOC signal modules.
CPU with PSU and local inputs/outputs
The CPU module of the XC100 has a compact design that is
divided into two functional units:
• Processor unit with interfaces
• 24 V PSU with integral digital inputs (eight) and digital outputs
(six).
24 V PSU with local inputs/outputs
The power supply unit provides the operating voltages required by
the processor unit and the inputs/outputs (local and
decentralized).
Function
The power supply transforms the 24 V DC supply voltage into the
voltages required by the system. These voltages are fed to the bus
on the basic rack unit and any expansion rack units that are
present.
The special feature of connection to the 24 V supply voltage is that
the processor unit and the local inputs/outputs can be fed
separately. One 24 V connection is provided for the processor unit
(labelled: 24V/0V) and another 24 V connection for the local
inputs/outputs (labelled: 24VQ/0VQ).

section.
Detailed information about the module racks and XIOC
modules can be found in the manual “Hardware and
Engineering, XIOC Signal modules”. This manual is
provided as a PDF file (h1452g.pdf) on the CD.
