Intended use

The CX5010 / CX5020 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”.

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 V

System Overview

The system

The CX5000 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 CX5000 series has a fixed, non­expandable number of system interfaces. The housing design for this series is optimised 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 commercially available DVI monitor can be connected to the DVI D 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 Compact Flash 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 Compact Flash card. The date and time are buffered via a replaceable battery. The
operating system can be Windows CE or Windows Embedded Standard. The TwinCAT automation software
transforms a CX5000 system into a powerful PLC and motion control system that can be operated with or without
visualisation.

EtherCAT as a fast I/O system

Like all Embedded PCs from the CX series (except CX100x), the CX5000 was developed for optimum interaction
with EtherCAT. One of the two independent Ethernet interfaces of the CPU module (X001) is intended for EtherCAT
mode. The primary EtherCAT connection is generally established via terminals. Both can also be configured as a ring
in order to achieve line redundancy.

Interestingly, EtherCAT offers several options for connecting conventional fieldbus systems to the CX50x0:
As EtherCAT device in terminal form, 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. It no longer
has to be implemented as a plug-in card in the IPC or a master controller in the control cabinet.

PLC, Motion Control, interpolation and visualisation

As a DIN rail IPC and in conjunction with the TwinCAT software from Beckhoff, the CX50x0 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. 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.

For CX50x0 the familiar basic principle applies: it is a programming tool for all controllers.

CX50x0 - Hardware Documentation 7

Notes on the documentation

The complete programming of PLC, Motion Control and visualisation 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.

Fieldbus interfaces

The fieldbus interfaces are currently available as master and slave versions for the following field busses:

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:

 CX50x0-N030 = RS232, D-Sub connector

 CX50x0-N031 = RS422/RS485, D-Sub socket

 CX50x0-M310 = PROFIBUS master, D-Sub socket, 9-pin

 CX50x0-B310 = PROFIBUS slave, D-Sub socket, 9-pin

 CX50x0-M510 = CANopen master, D-Sub connector, 9-pin

 CX50x0-B510 = CANopen slave, D-Sub connector, 9-pin

 CX50x0-M930 = PROFINET RT, controller, Ethernet (2 x RJ-45 switch)

 CX50x0-B930 = PROFINET RT, device, Ethernet (2 x RJ-45 switch)

 CX50x0-B951 = Ethernet/IP slave, Ethernet (2 x RJ-45 switch)

 CX50x0-B100 = EtherCAT slave, EtherCAT IN and OUT (2 x RJ 45)

The software

In combination with the TwinCAT automation software, the CX50x0 Industrial 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 realised.

The CX50x0 system is programmed in the same way as other bus controllers:

Remote programming via Ethernet

This option is used if the basic unit is equipped with “Windows CE.NET”. In this case, the system is programmed via
a laptop or a desktop PC, which is connected to the CX via Ethernet (network or crossover cable). The programs are
developed on the laptop with a standard TwinCAT software license and then loaded into the target device.

Visualisation

The Beckhoff OPC server is available for interfacing with SCADA packets, if the two operating system variants
“Windows CE.NET” or “Windows XP Embedded” are used. In other words, the CX50x0 also offers straightforward
visualisation and simultaneous control in real-time on a single system.

Notes on the documentation

CF slot

A Compact Flash slot is located at the front, which 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 Compact Flash 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). Compact Flash cards (CF cards) are available as accessories in various sizes.

The following images illustrate the handling of the CF cards. Open the front cover. Then eject mechanism and the CF
card slot are then visible. The eject mechanism is based on the push-push principle: If the head of the mechanical
system is retracted, pushing it makes it move out of the housing. Pushing the head again will lock it back in the
housing. At the same time the card moves approx. 4 mm out of the housing, so that it can be pulled out. If the card is
pushed in (FIGURE 3), the eject mechanism will re-engage. The card is positioned correctly, if it is located approx. 1
mm lower than the front of the housing.

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.

Type of CF slot

The Compact Flash slot is a memory interface, not an I/O type CF slot.

Notes on the documentation

CF card

The Compact-Flash card (CF card) is a non-volatile memory.

Data to be retained in the event of a power failure should be saved on the CF card. The CF card operates like a hard
disk.

Using CF cards

We strongly recommend that only CF cards supplied by Beckhoff Automation GmbH

should be used.

Note

These are industrial CF cards with a higher number of write/read cycles and an extended
temperature range (+85 °C).

Proper operation can only be guaranteed with CF cards from Beckhoff Automation GmbH!

Integration into a PLC

TwinCAT offers special function blocks for integrating the S-UPS into a PLC program. These are described below.
From TwinCAT 2.11R2 Build 2016 the required library is integrated in the installation. For older versions the library
TcSUPS.lib has to be copied into the TwinCAT library directory.

Notes on the documentation

FUNCTION_BLOCK FB_S_UPS

The function block FB_S_Ups can be used on PCs with Seconds UPS, to communicate from the PLC with the UPS.
The FB_S_Ups can be used to save persistent data and to QuickShutdown the PC in case of a power failure. The
INPUTs of the FB_S_UPS should be used with the default values.

Data loss

The Seconds UPS is only capable of holding the voltage for a few seconds. This is just
enough time to save the persistent data. The used persistent saving mode must be

Attention

"SPDM_2PASS", even though if this could causes realtime problems. The router memory
must be big enough in order to save the persistent data!

Mode eSUPS_WrPersistData_Shutdown (default setting): The persistenten data are written and a QuickShutdown is
automatically performed.

Mode eSUPS_WrPersistData_NoShutdown: Only the persistenten data are written, a QuickShutdown will not be
performed.

Mode eSUPS_ImmediateShutdown: a QuickShutdown is immediatelly performed.

Mode eSUPS_CheckPowerStatus: only the powerfailure will be detected, no action is performed. In case of the
powerfailure the FB waits until the tRecoverTime (10s) has expired before it goes back to the PowerOK state.

The UPS will switch off the main board after the capacitors have been discharged, independent of the mode and
therefore independent of the writing of the persistent data and of the QuickShutdown, even if the power supply is
restored.

The capacity of the UPS is to small to hold the system alive during longer power outages. The saving of the
persistent data has to be done to the Compact Flash, since a hard disk cannot be operated if the UPS supplies the
voltage. After the saving of the persistent data a QuickShutdown will be executed.

Attention if files are modified:

If other applications or the PLC are keeping files open or write to files during a power
failure, then these files can get corrupted, since the QuickShutdown immediately reboots

the PC.

Attention if using Windows XP embedded:

The EWF (Enhanced Write Filter) or the FBWF (File Based Write Filter) has to be activated
in order to ensure the validity of the Windows XP embedded files on systems with a

Attention

In case of the EWF the TwinCAT\Boot folder needs to be located on a not protected partition (see in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Beckhoff\TwinCAT\System\BootPrjPath).

In case of the FBWF the TwinCAT\Boot folder needs to be excluded from the protection (see Beckhoff FBWF

5. Operating/Configuration

EtherCAT cable redundancy

EtherCAT cable redundancy can be realised in the CX50x0 systems through the two independent Ethernet ports.
Minimum requirements:

1. EtherCAT redundancy supplement

2. EK1110 (bus extension)

3. EK1100 (Bus Coupler)

The supplement product on the Beckhoff website at

http://download.beckhoff.com/download/Software/TwinCAT/Supplement/TwinCAT_EtherCAT_Redundancy/Install/Tc
EcRedundancy.exe

can be downloaded. The required licence key can be ordered from our sales division. The required couplers are
ordered together with the other hardware. These components can then be used to configure the controller. The upper
figure shows a minimum configuration example for cable redundancy. Once the hardware has been wired and
commissioned, the supplement must be installed on the device, for example via a USB stick or the IT network. During
the installation the system asks for the licence key. The cable redundancy can be set up in the System Manager. The
first step involves reading the terminal configuration. Then select "Advanced Settings" under the "EtherCAT" tab in
the EtherCAT device properties. The second adapter can be set under the "Redundancy" menu. Use the "Search"

button to open the selection menu. Select "Local Area Connection 2 (Intel(R).....)" for the lower network connection

(X001). Click "OK" to complete the configuration.

CX50x0 - Hardware Documentation 37

Notes on the documentation

The supplement only supports CABLE REDUNDANCY

This supplement only supports cable redundancy, which means that only the cable sections
can be regarded as fail-safe, i.e. connections between the couplers.

Note

Failures of individual terminals are not covered.
Further details can be found in the Beckhoff Information System under EtherCAT cable
redundancy.

Cases of failure

The two possible failures are described in the example below.

38 CX50x0 - Hardware Documentation

Notes on the documentation

In this example the supply line for coupler EK1100 is faulty. The EK1100 terminals continue to run despite the cable
failure. The System Manager indicates the failure as follows:

The interruption is indicated by "LNK_MIS B" and "LNK_MIS A".

The next example shows a failure of the "return line":

CX50x0 - Hardware Documentation 39

Notes on the documentation

In this case the second cable is faulty. The terminals at the coupler continue to run without malfunction. The System
Manager indicates the behavior as follows:

The interruption is indicated by "LNK_MIS C" at coupler EK1100.

The EtherCAT ring is expandable. The number of devices in the ring is controlled by licenses: up to 250, up to 1000,
more than 1000. A master is only able to bridge one failure. In the event of two failures the ring components will
continue to run up to the breaking points.

40 CX50x0 - Hardware Documentation

Notes on the documentation

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.

Notes on the documentation

Note on using the setup

Changes in the BIOS settings may only be implemented by appropriately trained
staff.

The CX50x0 systems are delivered by Beckhoff Automation GmbH in a preconfigured state
and are therefore operational!

Attention

Within the individual setup pages, F6 can be used for loading fail-safe defaults, and F7 for optimised default values
for the individual setup entries. These default values are applied irrespective of whether the board was previously
booted successfully with a particular setup setting. The situation is different if the defaults are called from the TOP
menu. Once a setup setting that subsequently led to successful booting was saved, both menu items will load these
values as default for the setup pages. See also "Load Fail-Safe Defaults" and "Load Optimized Defaults".

The BIOS settings should only be executed by appropriately trained staff.
Under Windows CE the BIOS should not be changed at all, since the operating system is

adapted to the hardware configuration. Any change in the addresses or interrupts would
lead to unstable system behavior or even crashing.

Access Mode

This option can be used to select the operating system for the hard disk. Setting options: CHS, LBA, LARGE, or Auto.
Auto is the recommended setting. Normal (standard) mode supports hard disks with a capacity of up to 528 MB. This
mode uses positions for data access that are specified via cylinders (CYLS), heads, and sectors. The older LBA
(Logical Block Addressing) mode can support hard disks with a capacity of up to 8.4 GB. This mode uses a different
method for calculating the position disk data to be accessed. It translates cylinders, heads and sectors into a logical
address for the data location. Large hard disks support this mode. The BIOS supports the INT 13h extension function
that enables the LBA mode to manage hard disk drives with a capacity of more than 8.4 GB. If the number of
cylinders (CYLs) on the hard disk exceeds 1024 and DOS cannot support it, or if your operating system does not
support LBA mode, LARGE mode should be selected. The following options are available for setting the hard disk

memory). If the CPU requests data, the system transfers theses data from the main DRAM to the cache memory for
faster access by the CPU. Setting options: Enable (standard) - cache activated, Disabled - cache deactivated.

Quick Power On Self Test

If this option is enabled the computer will start significantly faster. Booting will be up to 50 seconds faster with 64 MB
RAM or more. However, not all POST tests are carried out.

This submenu can be used for setting the optimum timing for options, depending on the memory modules used. By
default the options are configured via 'By SPD', by reading the content of the SPD (Serial Presence Detect ) unit.
During this process critical parameter information relating to memory type, size, speed, voltage interface and module
banks are stored in the EEPROM.

System BIOS Cachable

If the function is active the cache memory makes use of the available BIOS-ROM, thereby enhancing the
performance, although this applies mainly to DOS and Win3.x. Under Windows 95/98 this option is less relevant.

Video BIOS Cachable

If this option is enabled, the cache memory can take the VIDEO BIOS of the graphics card at the address C0000h to
C7FFFh into account. Please note that caching involves risks, if the cache contains the code and a program wants to
write into the BIOS area. If this option is enabled, the option Video BIOS Shadow should also be activated. Under
DOS the speed benefits is around 40%. Under Win.x and DOS this option should be enabled, otherwise it should be

IDE Primary Master PIO

PIO refers to the concept of programmed input and output. Instead of the BIOS issuing an instruction sequence for
initiating a data transfer from or to the hard disk, PIO enables the BIOS to notify the controller what task should be
executed. The task is then fully handled by the controller and the CPU. Your system supports five PIO modes, 0
(standard) to 4, with the main difference relating to timing. If "Auto" (automatic) is selected, the BIOS will assess your

drive and automatically specify the optimum PIO mode. Auto: The BIOS automatically sets the system value

depending on the timing of your hard disk drive. Mode 0-4: You can select a mode suitable mode that matches the
timing your hard drive.

a power feed terminal, are not included in the count.

In the case of some errors, rectification does not cause the power supply to leave the blink sequence. The power
supply can only be restarted by switching its supply voltage off and on again.

Notes on the documentation

LEDs of the E-bus-power supply unit (CX50x0-0xxx)

After switching on, the power supply immediately checks the connected Bus Terminal configuration. Error-free start­up is signalled by the red "I/O ERR” LED being extinguished. If the ”I/O ERR" LED blinks, an error in the area of the
terminals is indicated. The error code can be determined from the frequency and number of blinks. This permits rapid
rectification of the error.

7. Decomissioning

Disassembly and disposal

A CX50x0 hardware configuration is dismantled in 2 stages:

1. Switching off and disconnecting the power supply

Before a CX50x0 system can be dismantled, the system should be switched off, and the power supply should be
disconnected.

2. Removing from the top-hat rail:

Before the individual modules are disconnected, the whole CX50x0 hardware block should be removed from the top­hat rail. Proceed as follows:

2.1. Release and remove the first Terminal next to the power supply unit on the top-hat rail.

First remove any wiring from power supply unit and then from the first terminal on the top-hat rail next to the power
supply unit. If the wiring is to be reused for another system, it is advisable to make a note of the connections. Then
pull the orange terminal release (see arrow) to release the terminal and pull it out.

2.2. Releasing the CX50x0 systems

To release the CX50x0 block, release the orange DIN rail bracket on the left-hand side of the device. Push back the
lower hook. An audible click indicates that the device is released.

After pulling the terminal release of the power supply unit, the block can be removed carefully from the top-hat rail.
