Product overview
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 24VDC.
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 installed on the PC that he can reach.

2.2 System overview
Product 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.
