2 Product overview
2.1 Intended use
The CX20x0 device series is a modular control system designed for DIN rail installation. The system is
scalable, so that the required modules can be assembled and installed in the control cabinet or terminal box
as required.
Only switch the PC off after closing the software
Before the Embedded PC is switched off, the software currently running on it should be stopped properly in
order to avoid data loss on the hard disk. Please read the section on “Switching off”.
Switch off all system components and uncouple the Industrial PC from the system if the PC is not used for
control purposes, e.g. during a function test. To disconnect first pull the first terminal behind the power
supply unit (optional), then pull the connectors of the fieldbus connections.
System components that have been switched off must be secured against being switched on again.
The Embedded PC’s power supply unit must be supplied with 24VDC.
NOTE
Damage to the environment or devices
Do not exchange any parts when under power! The exchange of controller parts when live can lead to
short-circuits or overvoltages. These can damage the controller itself and connected peripherals (terminals,
monitors, input devices, etc.).
When components are being fitted or removed, the supply voltage must be switched off.
Software knowledge
NOTE
System malfunctions
Mandatory software knowledge! Every user must be familiar with any of the functions of the software in-
stalled on the PC that he can reach.

2.2 System overview
CX2550-0x79 system module USB extension
The CX2550-0x79 systems modules are attachments for the CX2000 Embedded PC series. They transmit
USB signals via a CAT 5e cable over distances of up to max. 50 m. The CX2550-0179 system module
transmits USB signals according to the USB 1.1 standard (full speed, max. 12 Mbit/s) while the
CX2550-0279 system module transmits USB signals according to the USB 2.0 standard (high speed, max.
480 Mbit/s). Both modules can be attached at the right-hand side of a CX20x0-CPU and are placed between
the power supply unit and the CPU. The internal connection is made via a USB port of the CX20x0-CPU; this
way, no PCI Express resources are required or used. No additional drivers are required for operation since
signal transformation and forwarding of the USB signals take place at the electrical level and are completely
transparent for the operating system.
The CX2550-0179 and CX2550-0279 modules enable the direct connection of Beckhoff Control Panels with
USB Extended interface. The CX2550-0179 system module is suitable for the connection of the Beckhoff
CP69xx and CP79xx Control Panel series with USB Extended 1.1 connection. The CX2550-0279 system
module is suitable for the connection of the Beckhoff CP29xx and CP39xx Control Panel series with USB
Extended 2.0 connection.

3 Mounting and wiring
3.1 Unpacking, installation and transport
The specified storage conditions must be adhered to (see "Technical data").
Dimensions and weight of the individual modules:
Dimensions (W x H x D): 24 mm x 100 mm x 55 mm
Weight: approx. 195 g (system interface)
Unpacking
Proceed as follows to unpack the unit:
1. Remove packaging.
2. Do not discard the original packaging. Keep it for transporting the device in the future.
3. Check the delivery for completeness by comparing it with your order.
4. Please keep the associated paperwork. It contains important information for handling the unit.
5. Check the contents for visible shipping damage.
6. If you notice any shipping damage or inconsistencies between the contents and your order, you
should notify Beckhoff Service.
NOTE
Danger of damage to the device!
During transport in cold conditions, or if the device is subjected to extreme temperature differences, con-
densation on and inside the device must be avoided. Prior to operation, the device must be allowed to
slowly adjust to room temperature. Should condensation occur, a delay time of approximately 12 hours
must be allowed before the unit is switched on.
Installation
The devices are designed for installation in control cabinets.
Shipping and relocation
Despite the robust design of the unit, the components are sensitive to strong vibrations and impacts. During
transport, your computer should therefore be protected from excessive mechanical stress. Therefore, please
use the original packaging.

3.3 Attaching the system interface to the CX20x0 system
The USB extension is positioned directly between the CPU and the power supply unit.
When the module is connected to the CPU it engages audibly.
Further modules can be connected to the system in the same way. Please note that some modules are
connected on the left-hand side of the CPU. Once all modules are connected, the system can be placed on
the DIN rail as a block. For details please refer to the section on DIN rail mounting.
Maximum number of extension modules
Up to two extension modules can be attached on the right-hand side of the system.
3.4 Installation on the mounting rail
Snapping onto the mounting rail
The CX20x0 can simply be snapped onto the mounting rail. The bar clips are inserted on the top side and
underside Then simply position the block on the mounting rail and push it slightly until it engages on the
right-hand side. This is indicated by a distinct click. The bars are then engaged again. The engagement of
the individual bars is indicated by a distinct click.

CX2550-0x79 15Version: 1.0
NOTE
Avoid damage!
Do not force the module or apply excessive pressure!
Installation position
NOTE
Comply with the permitted installation position and minimum distances!
The maximum ambient temperature for CPU modules mounted on a DIN rail is 60°C. The orientation in
which the device is fitted must be selected in such a way that cooling air can flow vertically through the ven-
tilation holes. The images below show the permitted and two incorrect installation positions. Mounting must
provide a clearance of 30 mm both above and below a CX20x0 device combination to ensure adequate
ventilation of the base CPU module and the power supply unit.
Correct installation position
The high performance and the compact design of the CX20x0 systems may result in increased heat
generation. The heat is dissipated via a passive ventilation system. This system requires the unit to be
mounted correctly. Ventilation openings are located at the top and bottom of the housing. The system
therefore has to be installed horizontally. This ensures optimum air flow.

Mounting and wiring
CX2550-0x7916 Version: 1.0
Incorrect installation positions
The CX20x0 system must not be operated vertically on the DIN rail. A vertical position would lead to
insufficient CPU ventilation, since the ventilation openings are located on the top and bottom of the housing.
Installation of the system on its side would also lead to inadequate ventilation.

CX2550-0x79 17Version: 1.0
3.5 Mounting the module lock
Mounting the lock
The CX20x0 controller system is fully modular, i.e. all system interfaces of the system are field-configurable.
As a rule the latching of the modules to each other is sufficiently strong. However, it is possible for the
controller and its modules to be exposed to vibrations, shocks or impacts. The modules can be securely
connected to one another with the aid of bar clips.
The bar clips are inserted on the top side and underside.
If all system interfaces are locked, then the entire assembly can be snapped onto the support rail.
Dismounting the lock
In order to dismantle the assembly it must first be removed from the support rail. Afterwards the bar clips can
be removed with the aid of a screwdriver:

Mounting and wiring

Once the bar clips have been raised they can be pulled out. Subsequently, the system interfaces can be
separated again.

Commissioning / Configuration
CX2550-0x7920 Version: 1.0
4 Commissioning / Configuration
4.1 Switching on and off
Switching on
The power supply for the basic CPU module comes from the power supply unit. The basic CPU module
starts automatically when the power supply unit is connected to the mains.
Switching on for the first time
When you switch on the PC for the first time, the pre-installed operating system (optional) will be started.
Switching off
The Embedded PC switches off when the power supply unit is switched off. The control software typically
running on Embedded PCs should be shut down or stopped correctly. A user who may not close software
may also not switch the Embedded PC off, since data can be lost from the hard disk by switching off while
software is running.
Once the software has been stopped, the operating system can be shut down. Only then should the power
supply be interrupted.
