Product Overview

System Overview

The System

The CX1000 system covers the whole range of Beckhoff control technology both in terms of price and performance:
The new 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 those components that are actually required. For example, a CX1000 can be operated in
„headless“mode, i.e. without display or keyboard; in this case, the associated interface is not required. Whilst the
resulting control system has no visualisation, it does have communications capability via the built-in Ethernet and RS
232 interfaces.

If local visualisation is required, this can be implemented via a DVI (digital video interface), to which all Beckhoff
Control Panels and all commercially available monitors with DVI-input can be connected. The touch screen signal is
read via one of the two available USB interfaces.

The components

The modules of the CX1000 series system are connected with each other via the standardised PC104 bus (16 bit).
The individual system components are modules that can be arranged in series. The basic unit consists of a CPU
module(CX1000-0000) and a power supply module(CX1100-000x). Further system interfaces for serial
communication(2x RS 232, and RS422, RS485) as well as audio signals are available separately.

CPU base module

The CPU module is available in several variants. These relate to:
– Internal memory configuration: there are two options – either 16 MB Flash/32 MB RAM or 64 MB Flash / 128 MB

RAM. The latter is required if the system is to be equipped with Windows XP Embedded.
– System interface configuration: as an option, a DVI and two USB Interfaces can be added to the combination of

Ethernet and RS 232 that is always present.
– Operating system: There is a choice between Microsoft Windows CE.NET and Microsoft Windows XP Embedded.
– Pre-installed TwinCAT software: CX1000 can be preinstalled without a TwinCAT system, with TwinCAT CE PLC or

with TwinCAT CE NC PTP, or with the associated full version of the individual TwinCAT levels for PLC and Motion
Control.

Embedded PC 7

Product Overview

System interfaces

Further system interfaces for serial communication(2x RS 232, and RS422, RS485) as well as audio signals are
available separately.

Fieldbus interfaces

The range of optional modules for theCX1000 is complemented by fieldbus connectionsfor Profibus, CANopen,
DeviceNet,SERCOS interface and Lightbus, both asmaster and slave versions.

The following fieldbus interfaces are available:
Beckhoff Lightbus (master and slave), Profibus DP (master and slave), CANopen (master and slave), DeviceNet

(master and slave) und SERCOS Interface (only master).
The use of fieldbus master modules in a CX1000 system enables the utilisation of all Beckhoff fieldbus components

(e. g. Bus Coupler, Bus Terminal Controller, drive technology) as distributed control components for the assembly of
complex systems

The use of fieldbus slave modules enables the utilisation of a CX1000 system as subordinate distributed control for
the configuration of complex or modular systems.

The Software

In combination with the TwinCAT automation software, the CX1000 Industrial PC becomes a powerful IEC 61131-3
PLC with up to four user tasks. Additionally, MotionControl 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 CX1000 system can be programmed in two ways, depending on the operating system used:

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 CX1000 via Ethernet (network or crossover cable). The programs
are developed on the laptop with a standard TwinCAT software licence and then loaded into the target device.

Visualisation

The Beckhoff OPC server is available for interfacing with SCADA software on both operating system variants
Windows CE.NET or Windows XP Embedded. In other words, the CX1000 also offers unproblematic visualisation
and simultaneous control in realtime on a single system. Beckhoff control devices

Product Overview

Compact Flash slot

A Compact Flash slot is provided at the front of the basic CPU module. This enables an additional Compact Flash
memory medium (format I or II) to be operated. The change is only allowed while the system is powered down ­otherwise the system could crash. The card can be removed for maintenance or to extend the system storage
capacity. The Compact Flash cards (CF cards) are available as accessories with different storage capacities. It is

Activating the eject mechanism below the slot with a screwdriver causes the card to be ejected by approx. 4 mm
(FIGURE 1), so that it can be pulled out (FIGURE 2). 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.

Product Overview

CX1100-0002 Connections

This power supply unit is equipped with an I/O interface, which permits connection of the Beckhoff Bus Terminals.
The power is supplied via the upper spring-loaded terminals labelled “24V” and “0V”.
The supply voltage feeds the CX system and supplies a voltage of 24 V DC (-15 %/+20%) to the Bus Terminals via
the K-Bus. The dielectric strength of the power supply unit is 500 V
on, a further power supply is necessary for the Bus Terminals. This is provided by means of the power contacts,
which are not connected to the power supply.
The integrated NOVRAM permits storage of process data that is safe against power failure.

LED:

With proper connection of the power supply unit and with power supply turned on, the power LED (PWR) lights up
green. In the case of a short-circuit, it lights up red.

The I/O LEDs display the operation status of the Bus Terminals. Error-free start-up of the configuration 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.

Product Overview

CX1100-0003 Connections

This power supply unit permits not only the connection of the Beckhoff Bus Terminals, but also the serial connection
of the Beckhoff fieldbus box modules of the type extension box IExxxx. The power is supplied via the upper spring­loaded terminals labelled “24V” and “0V”.
The supply voltage feeds the CX system and, over the K-Bus, the Bus Terminals. Since the K-Bus does no more
than pass data on, a further power supply is necessary for the Bus Terminals. This is provided by means of the
power contacts, which are not connected to the power supply.

Fieldbus connection:

Plug the IP link connector into the respective connections, i.e. one fibre-optic cable each into IN (x03) and OUT (x04).
You then connect the other end with the corresponding IP link interface of the extension box. The connection must be
made so that the output of the fieldbus connection is connected to the input of the extension box and vice versa.

Dimensions

The CX1000 product range is characterised by small overall installed size and high modularity. For project planning
purposes, a CPU module, a power supply unit and the associated system interfaces and fieldbus interfaces have to
be provided.
The overall width of the application is made up of the individual modules.
With a height of 100 mm, the module dimensions exactly match those of the Beckhoff Bus Terminals. Together with
the lowered connector surfaces, this means that it can be used in a standard terminal box with a height of 120 mm.

Basic CX1000 CPU modules:

The basic CPU module measures 57 x 100 x 91mm.

CX1000-N00x system interfaces:

The four system interfaces all measure 19 x 100 x 91 mm.

connection is used.

Embedded PC 31

Fitting and wiring

Mechanical Assembly of the base module

The installation of the modules takes place in three steps:

1. The Sequence of the Modules

The CPU basic module with system interfaces, which are factory-installed on the left side, is extended with the power
supply unit on the right and with the fieldbus connection (master or slave) left side if available. The mounting of an
filedbus module is described on the next page.

2. Assembly with Other Modules

The attachment of the individual modules is done by simple plugging them together (FIG. 1). Care must be taken that
the plug of the PC104 interface is not damaged.
When correctly assembled, no significant gap can be seen between the attached housings.

FIG. 1: Engaging of the Modules

3. Engaging on the top-hat rail

On the bottom of the modules, there is a white tension strap, which is connected with a latching mechanism. These
tension straps must be pulled down before attaching to the mounting rail. This can be done with a slotted screwdriver
and a small rotation. (FIG. 4). After engaging the module on the top-hat rail successfully (FIG. 5), the tension straps
must be shifted into the starting position again (FIG. 6).

FIG. 4: Tension straps down FIG. 5: Engaging on the top-hat rail

FIG. 6: Tension straps back in starting position FIG.7: Tension straps not engaged / engaged

Note:

A locking mechanism prevents the individual housings from being pulled off again. More detailed information about
disassembling the CX configuration from the top-hat rail can be found on the page decommissioning.

By lowering the front surfaces, which contain the interfaces, installation can easily be done in a standard terminal box
of 120 mm height.

Installation position:

Warning

The CPU module installed on a top-hat rail may be operated only in case of ambient temperatures
up to 55°C. The orientation in which the device is fitted must be selected in such a way that cooling
air can flow vertically through the ventilation holes. The images show the permitted ( FIG. 8 and
FIG. 9) as well as a forbidden installation positions (FIG. 10).

Observe minimum clearance!

Mounting must provide a clearance of 30 mm both above and below a CX1000 device combination
to ensure adequate ventilation of the CPU base module and the power supply unit.

Mechanical mounting of the Fieldbus modules

The mounting of the Fieldbus modules takes place in several
steps:

1. Remove cover at CX1000/CX1020 basic module

In order to be able to fasten the connection of the fieldbus connection to the CPU basic module, the cover must first
be removed (FIG 1, 2). This can be achieved by a small pressure against the cover.

FIG.1+2: Remove Cover

2. Assembly with CX1000/CX1020 configuration

Because the CX1000 configuration is already on the top-hat rail, the fieldbus module first has to be pressed on the
top-hat rail. For that purpose the locking of the latching mechanism with the white tension straps (pull down) is
required.

The attachment of the individual modules is done by simple plugging them together (FIG. 3). Care must be taken that
the plug of the PC104 interface is not damaged.
When correctly assembled, no significant gap can be seen between the attached housings. At the end the white
tension strips must be shifted into the starting position again in order that the latching mechanism locks.

FIG. 3: Stick modules together

Embedded PC 35

Fitting and wiring

FIG. 4: Tension straps back in starting position

3. Attach Cover

If the connection area does not have a closing cover on the left-hand side, the cover that was previously removed
should be pressed over the connections until it audibly engages.

Note:

If the CX1000/CX1020 configuration is not positioned on the top-hat rail it is possible to join the connection first with
the CX1000/CX1020 configuration, as shown in FIG. 3, and then to clip the entire module onto the top-hat rail.

Note:

A locking mechanism prevents the individual housings from being pulled off again.

Decommissioning

6. Decommissioning

Removal and disposal

A CX1000 hardware configuration is dismantled in 2 stages:

1. Removing from the top-hat rail:

The white straps on the underneath of all the modules must be pulled downwards (FIG 1). This can be done using an
ordinary screwdriver and a slight turn. The latching mechanism that provides fixing to the top-hat rail opens up (this
procedure is not visible).

If the configuration has a power supply unit with an I/O interfaces, it is first necessary to release the first terminal from
the top-hat rail (FIG 2) so that the CX1000 configuration can be separated from the I/O hardware, allowing the
module to be removed from the top-hat rail (FIG 3).

FIG 1: Straps down FIG. 2: Releasing the I/O terminal from the top-hat rail

FIG. 3: Separating the module from the top-hat rail

2. Separating the individual modules:

Before separating the individual modules from one another, the entire CX1000 hardware block must first be removed
from the top-hat rail, as described in Step 1. The individual modules can then be separated from one another by
means of the separation mechanism mounted on the rear, as shown in Fig 4. This is done by inserting a flat
screwdriver with dimensions 1.0 x 5.5 x 150 mm into the locking mechanism, and then operating the slider by turning
it about 90 degrees. The rear-mounted locking mechanism creates a separation of approx. 2-3 mm in the mechanical
engagement of the modules, pushing them apart, so that the PC 104 interface connectors can then carefully be
pulled apart (FIG 5). Modules that cannot be separated from one another do not have a slider slot, but merely a
marking point (which may or may not be sealed with red lacquer). Applying force to these elements will destroy them.

Note:

If the configuration has a power supply unit with an I/O interface, it is first necessary to release one terminal from the
top-hat rail so that the configuration can be separated from the I/O hardware.

Note:

The embedded PC must be shut down and the power supply disconnected before dismantling!

Warning

Forcibly opening the module housing (e.g. removing the cover) will destroy the housing.

Disposal

The device must be fully dismantled in order to dispose of it.
Electronic parts must be disposed of in accordance with national electronics scrap regulations.
