Controller Structure
The XCx 1100 is a modular automation system where up to 256
modules can be arranged on a maximum of 16 racks.
Important!
The automation system must be installed in earthed metal
housings (e.g. enclosures). Observe the regulations described in
the "EMC Guidelines for the Structure of Automation Devices"
documentation (
The CPU is a module with a Promodul-U system design. The
installation height and depth are designed accordingly. The CPU
module (CPU and heat sink) occupy the width of four standard U-
modules in total.
Components that are susceptible to wear, such as fans or hard disks,
are dispensed with to achieve the highest possible level of operating
safety and the lowest level of maintenance.
Compact Flash or Solid State Discs are used for storing programs and
data.
The backplane has a mechanically separated design. The U-periphery
is located to the right of the CPU and the power supply unit is located
on the left. This module supplies the CPU and the U bus with the
required operating voltages.
