Product overview
2 Product overview
2.1 Intended use
The CX51x0 device series is a modular control system designed for top-hat 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 [}84]”.
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.
Attention
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 con-
nected peripherals (terminals, monitors, input devices, etc.).
When components are being fitted or removed, the supply voltage must be switched off.
Software knowledge
Attention
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.

Product overview
2.2 System overview
The system
The CX51x0 series devices are DIN rail-mountable, fanless Embedded PCs with direct connection for
Beckhoff Bus Terminals or EtherCAT Terminals. In contrast to the other CX device families, the CX51x0
series has a fixed, non-expandable number of system interfaces. The housing design for this series is
optimized for robustness and compactness. No modular expandability for the left-hand side is provided.
Although EtherCAT integration offers a wide range of expansion capability. Further master/slave fieldbus
connections (PROFIBUS, CANopen, DeviceNet) or communication interfaces (RS232, RS422/RS485) and
all other signal types accessible via EtherCAT can be directly connected as EtherCAT Terminals. Two
independent Gigabit Ethernet ports and four USB 2.0 interfaces are available. A Beckhoff Control Panel or a
standard DVI monitor can be connected to the DVI-I interface. A serial port (RS232/RS422/RS485) or a
fieldbus connection with master or slave function can be added as an optional interface as required. An
interchangeable CFast card located behind a flap that is accessible from outside is used as boot and storage
medium. The built-in capacitive 1-second UPS ensures secure backup of persistent application data on the
CFast card. The date and time are buffered via a replaceable battery. The operating system is Microsoft
Windows Embedded Standard 7 Professional. The TwinCAT automation software transforms a
CX51x0system into powerful PLC and Motion Control system that can be operated with or without
visualization.
EtherCAT as a fast I/O system
Like all Embedded PCs from the CX series (except CX100x), the CX51x0 was developed for optimum
interaction with EtherCAT. The primary EtherCAT connection is generally established via terminals. This is
where E-Bus Terminals are attached. In addition, one of the Ethernet interfaces of the CPU module (X001) is
parameterized for EtherCAT operation, and external EtherCAT components can be connected. To achieve
line redundancy, both interfaces can be interconnected as a ring.
EtherCAT offers several options for connecting conventional fieldbus systems to the CX51x0. EtherCAT
devices in terminal form provide several fieldbus masters and slaves, for example the PROFIBUS master as
EtherCAT Terminal EL6731. In practice, this means that the PROFIBUS master can be positioned exactly
where it is required within a machine.
PLC, Motion Control, interpolation and visualization
As a DIN rail IPC and in conjunction with the TwinCAT software from Beckhoff, the CX51x0 offers the same
functionality as large Industrial PCs. In terms of PLC, up to four virtual IEC 61131 CPUs can be programmed
with up to four tasks each, with a minimum cycle time of 50 μs. All IEC 61131-3 languages can be used.
Moreover, all TwinCAT functionalities are available for Motion Control applications:
in theory, up to 256 axes can be controlled and in addition to simple point-to-point movements, more
complex multi-axis functions such as “electronic gearbox”, “cam plates” and “flying saw” can be
implemented.
In addition to real-time execution of control tasks, the TwinCAT real-time kernel ensures that enough time
remains for the user interface (HMI), to communicate with the real-time components via software interfaces
such as ADS or OPC.
CX51x0 9Version: 1.6

Product overview
For CX51x0 the familiar basic principle applies: it is a programming tool for all controllers.
The complete programming of PLC, Motion Control and visualization is transferable to all PC controls from
Beckhoff, which is reassuring in cases where it becomes apparent during a project that more processing
power is required after all. In this case a system with higher performance can be used.
Optional interfaces:
The optional interfaces can be used to connect single-channel fieldbus interfaces. Operation is limited to one
interface at a time. If several fieldbus interfaces are required, they can be added as E-bus terminals
(EL67xx). The following fieldbus interfaces are available:
• CX51x0-N030 = RS232, D-Sub connector
• CX51x0-N031 = RS422/RS485, D-Sub socket
• CX51x0-M310 = PROFIBUS master, D-Sub socket, 9-pin
• CX51x0-B310 = PROFIBUS slave, D-Sub socket, 9-pin
• CX51x0-M510 = CANopen master, D-Sub connector, 9-pin
• CX51x0-B510 = CANopen slave, D-Sub connector, 9-pin
• CX51x0-M930 = PROFINET RT, controller, Ethernet (2 x RJ-45 switch)
• CX51x0-B930 = PROFINET RT, device, Ethernet (2 x RJ-45 switch)
• CX51x0-B951 = Ethernet/IP slave, Ethernet (2 x RJ-45 switch)
• CX51x0-B100 = EtherCAT slave, EtherCAT IN and OUT (2 x RJ 45)
• CX5130-N020 = second DVI-D interface
• CX5140-N020 = second DVI-D interface
The software
In combination with the TwinCAT automation software, the CX51x0 Embedded PC becomes a powerful IEC
61131-3 PLC with up to four user tasks. Additionally, Motion Control tasks can also be executed. Depending
on the required cycle time, several servo axes can be controlled. Even special functions such as “flying saw”,
“electronic gearbox” and cam plate can be realized.
The CX51x0 system is programmed in the same way as other bus controllers:
Remote programming via Ethernet
The CPU generally features a PLC runtime. A laptop or a desktop PC connected with the CX via Ethernet
(network) is used for programming. The programs are developed on the laptop with a standard TwinCAT
software license and then loaded into the target device.
Visualization
The visualization feature integrated in TwinCAT can be used, or one of the other commercially available
visualization solutions. The Beckhoff OPC server is available for interfacing with SCADA packages. In other
words, the CX51x0 also offers visualization and simultaneous control in real-time on a single system.

2.7 Architecture overview
The Embedded PCs of the CX51x0 family all have the same architecture. This is described below.
The CX51x0 Embedded PCs are based on the Intel Atom microarchitecture, which was developed by Intel.
The CPUs used in the CX51x0 family are:
• Intel®AtomTM E3815 (Singlecore)
• Intel®AtomTM E3827 (Dualcore)
• Intel®AtomTM E3845 (Quadcore)
In addition to the arithmetic unit, the CPU also contains the memory controller and the graphics controller.
The processors use the Intel® HD Graphics core. For details on the CPUs please refer to Intel. The memory
is connected directly to the CPU. The EPC is available in two memory configurations: 2 GB and 4 GB DDR3
RAM. The memory is not expandable and must be ordered ex factory.
The CPU provides all required interfaces:
• 1 PCIe lane for each of the two Intel® i210 Gigabit Ethernet controllers
• 4x USB 2.0 (interfaces)
• DVI-I and DVI-D interface (second interface optional in CX51x0-N010)
• Serial interface (CX51x0-N03x)
• 1 PCIe for FPGA for K-/E-bus and NOV-RAM
• 1 SATA for CFast card interface
• 1 IDE for Micro SD card interface
CX51x016 Version: 1.6

Product overview
The interfaces (USB, DVI, and LAN ports) are standard interfaces. They can be used for operating devices
that comply with the standard. The DVI-I port can be used to connect a VGA monitor via an adapter. If a
breakout cable separating DVI and VGA is used, both types can be operated simultaneously. If the optional
CX20x0-N010 interface (second DVI-D port) is used, either the VGA or the DVI port only can be used.
Intel® i210 Gigabit Ethernet controllers are used as network controllers. There are two independent ports,
which are both gigabit-capable.
Details of the individual system interfaces are described in separate sections.

Product overview
2.9 CFast slot
A CFast slot is located at the front. It enables the storage medium to be replaced. In the basic module this
should only be done in switched-off state, otherwise the system may crash. The CFast card can be
removed from the module for maintenance. In this way it is also possible to expand the system (only
operating system and program memory). CFast cards with different memory sizes are available as
accessories.
The following images illustrate the handling of the CFast cards. First, open the front flap. The CFast card slot
is then accessible. The eject mechanism is based on the push-push principle: Pressing the CFast card
causes it to be lifted out of the housing by approx. 4 mm, so that it can grasped by the fingers and pulled out.
When the card is pushed back the eject mechanism locks again. The card is positioned correctly, if it is
located approx. 1 mm lower than the front of the housing.
Once the flap is closed the device is ready for operation again.
