Beckhoff Embedded-PC CX

Modular DIN rail Industrial PCs

With the CX series of Embedded PCs, Beckhoff has combined PC technology and modular I/O level to form a DIN rail unit in the control cabinet. The CX device series combines the worlds of Industrial PC and hardware PLC and is suitable for medium-performance control tasks. The modular control system can be configured to match the task in hand and can be installed in the control cabinet or the terminal box.

The CX system covers the whole range of Beckhoff control technology both in terms of price and performance: this product range is designed for tasks requiring the characteristics and computing capacity of Industrial PCs, but whose budget does not stretch to full-blown Industrial PCs. The system only uses the components that are actually required. For example, a CX can be operated in “headless” mode, i.e. without display or keyboard; in this case, the associated interface is not required.

 

Scalable performance classes

The CX family includes several basic CPU modules with different processors for optimum adaptation to the respective control task:

CX1030: high-performance CX with Intel® Pentium® M CPU, 1.8 GHz processor

CX1020: high-performance CX with Intel® Celeron® M ULV CPU, 1 GHz processor

CX5020: compact CX with Intel® Atom™ CPU, 1.6 GHz processor

CX5010: compact CX with Intel®Atom™ CPU, 1.1 GHz processor

CX1010: basic CX with Pentium® MMX-compatible CPU, 500 MHz processor

CX9010: Ethernet controller with Intel® IXP420 XScale® technology, 533 MHz processor

CX9000: Ethernet controller with Intel® IXP420 XScale® technology, 266 MHz processor

CX8000: basic CX with ARM9 CPU, 400 MHz processor, and integrated fieldbus interface

Apart from various CPUs, the individual CX types also have different system interfaces and power supply units. Via associated I/O interfaces the Embedded PCs support Beckhoff Bus Terminals and also EtherCAT Terminals as I/O system.

 

Bus Terminals

The I/O signals are wired in a decentralised way to fieldbus devices or centrally to the controller. The available manufacturer-specific fieldbus devices with fixed input/output configurations and design often make it necessary to use an entire group of devices with similar functions. This costly method of signal acquisition gives rise to high material, installation, planning and documentation costs as well as high costs for subsequent modification or expansion. Inventory management and service staff are put under unnecessary strain.

 

Flexible and stable

The Beckhoff Bus Terminal is an open and fieldbus-neutral I/O system consisting of electronic terminal blocks. The head of an electronic terminal block is the Bus Coupler with the interface to the fieldbus. Bus Couplers are available for the following bus systems:

  • EtherCAT, the fast real-time Ethernet fieldbus,
  • Lightbus, the fast fibre optic fieldbus,
  • PROFIBUS DP/FMS conforms to the European standard EN 50170,
  • Interbus, which has been on the market since 1987,
  • CANopen, multi-masters in the actuator/sensor area,
  • DeviceNet, the device bus with CAN technology,
  • ControlNet, the standardised fieldbus,
  • Modbus, the open fieldbus,
  • Fipio, the fieldbus according to the WorldFIP standard,
  • CC-Link, the fieldbus for the Asian market,
  • SERCOS interface, the bus from the drives engineering field,
  • RS232/RS485, the network for the most economical solution,
  • Ethernet TCP/IP, the network bus,
  • Ethernet/IP, Industrial Ethernet solution from ODVA,
  • PROFINET, Industrial Ethernet solution from PNO,
  • USB, the fast interface for the laboratory.

With the master terminals, fieldbus functionalities are also available in form of a standard Bus Terminal. This is particularly advantageous for bus systems that are integrated as subsystems into a higher-level system. It means that only one system is required for the subsystem and for the higher-level bus interface. Master terminals are available for the following bus systems:

  • AS-Interface, the sensor/actuator bus for the lower control level,
  • EIB, LON, DALI, i.e. the communication standards in building automation.
