Product overview
2.1
Intended use
The CX9020 device series is a control system designed for DIN rail installation. The system can be 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 VDC.
Damage to the environment or devices
Attention
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
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
The system
The CX9020 is a compact, DIN rail-mountable Ethernet control system with 1 GHz ARM Cortex™ A8 CPU.
The connection for the Beckhoff I/O systems is directly integrated into the CPU module. The unit offers
automatic bus system identifi cation (K-bus or E-bus) and independently switches in the corresponding
mode. The CX9020 comprises the CPU with two microSD card slots, the internal RAM and 128 kB NOVRAM
as nonvolatile memory. The basic configuration also includes two switched Ethernet RJ 45 interfaces, four
USB-2.0 interfaces and a DVI-D interface. The RJ 45 interfaces are connected to an internal switch and offer
a simple option for creating a line topology without the need for additional Ethernet switches. The operating
system is Microsoft Windows Embedded Compact 7. TwinCAT 2 automation software transforms a CX9020
system into a powerful PLC and Motion Control system that can be operated with or without visualisation.
Optionally, the unit can be ordered with a fi eldbus, serial or audio interface.
The extended operating temperature range between -25 and +60 °C enables application in climatically
demanding situations.
EtherCAT as a fast I/O system
The CX9020 Embedded PC was developed for optimum interaction with EtherCAT.
Interestingly, EtherCAT offers several options for connecting conventional fieldbus systems to the CX9020:
As an EtherCAT device in terminal form. The PROFIBUS master is available either as a CX1500-M310 or as
a EL6731 EtherCAT terminal. 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 CX9020 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. 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.

Version: 1.5
CX9020
Product overview
For CX9020 the familiar basic principle applies: it is a programming tool for all controllers.
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.
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:
• CX9020-N020 = Audio, 3 x 3.5 mm jack plugs, Line-In, Mic-In, Line-Out
• CX9020-N030 = RS232, D-Sub connector, 9-pin
• CX9020-N031 = RS422/RS485,D-Sub socket, 9-pin
• CX9020-B110 = EtherCAT slave, EtherCAT IN und OUT (2 x RJ 45)
• CX9020-M310 = PROFIBUS master, D-Sub socket, 9-pin
• CX9020-B310 = PROFIBUS slave,D-Sub socket, 9-pin
• CX9020-M510 = CANopen master, D-Sub socket, 9-pin
• CX9020-B510 = CANopen slave, D-Sub socket, 9-pin
• CX9020-M930 = PROFINET RT, controller Ethernet (2 x RJ 45)
• CX9020-B930 = PROFINET RT, device, Ethernet (2 x RJ-45-Switch)
• CX9020-B950 = EtherNet/IP slave, Ethernet (2 x RJ-45-Switch)
The software
In combination with the TwinCAT automation software, the CX9020 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.
The CX9020 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 Embedded Compact 7”. 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 licence and
then loaded into the target device.

Micro-SD slot
Two µSD Flash slots are located at the front, which enables the storage medium to be replaced. This allows
the storage medium to be exchanged. The card in the upper slot (Slot 1) is used for the operating system.
The lower slot (Slot 2) is used for an additional µSD card. Here data or further programs can be archvied.
The µSD Flash card can be removed from the module for maintenance. This should only be done in
switched-off state, otherwise the system may crash. In this way it is also possible to expand the system
(only operating system and program memory). MicroSD Flash cards (µSD cards) are available as accessories
[} 48] in various sizes.
The following images illustrate the handling of the µSD cards. The eject mechanism is based on the pushpush principle: The CFast Flash card is disengaged with a soft click by lightly pressing the card ( with a
screwdriver) . At the same time the card moves approx. 2-3 mm out of the housing, so that it can be 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.

Installation on the mounting rail
Snapping onto the mounting rail
The CX9020 can simply be snapped onto the mounting rail. The bar clips are inserted on the top side and
underside Then simply position the block on the mounting rail and push it slightly until it engages on the
right-hand side. This is indicated by a distinct click. The bars are then engaged again. The engagement of
the individual bars is indicated by a distinct click.
Avoid damage!
Do not force the module or apply excessive pressure!
Attention
Installation position
Comply with the permitted installation position and minimum distances!
Attention
CX9020
The maximum ambient temperature for CPU modules mounted on a top-hat rail is 60°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 below show the permitted and
two incorrect installation positions. Mounting must provide a clearance of 30 mm both
above and below a CX9020 device combination to ensure adequate ventilation of the base
CPU module and the power supply unit.
Version: 1.5
19
Mounting and wiring
Correct installation position
The high performance and the compact design of the CX9020 systems may result in increased heat
generation. The heat is dissipated via a passive ventilation system. This system requires the unit to be
mounted correctly. Ventilation openings are located at the top and bottom of the housing. The system
therefore has to be installed horizontally. This ensures optimum air flow.
Incorrect installation positions
The CX9020 system must not be operated vertically on the top-hat rail. A vertical position would lead to
insufficient CPU ventilation, since the ventilation openings are located on the top and bottom of the housing.
Installation of the system on its side would also lead to inadequate ventilation.

Power supply
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 labeled “24V” and “0V”.
The supply voltage supplies the CX system ant the terminal Bus and Bus Terminal with a voltage of 24 V DC
(-15 %/+20 %). The dielectric strength of the power supply unit is 500 Vrms. Since the Terminal Bus (K- and
E-bus) only transfers data, a separate power supply is required for the Bus Terminals. This is provided by
means of the power contacts, which are not connected to the power supply.
Requirements for the 24V power supply
The power supply must be capable to supply 4A at 24 V to guarantee proper function of CPU CX9020
module and terminals.
CX9020
Version: 1.5

Mounting and wiring
The terminals are implemented in spring force technology. Connect the cables as follows:
1. Open a spring-loaded terminal by slightly pushing with a screwdriver or a rod into the square opening
above the terminal.
2. The wire can now be inserted into the round terminal opening without any force.
3. The terminal closes automatically when the pressure is released, holding the wire securely and
permanently.

Note
EtherCAT Bus Terminals (ELxxxx/ESxxxx) that do not actively participate in data exchange
within the Bus Terminal block are called passive terminals. These terminals can be recognised by their lack of power consumption from the E-Bus. In order to ensure optimal data
exchange, these may not be connected directly in-line to the power supply!

DVI-D port
DVI-D port (X200)
The DVI-D interface transfers digital data and is suitable for connecting a digital display. The resolution at the
display or the Beckhoff Control Panel depends on the distance from the display device. The maximum
distance is 5 m. Beckhoff offers various Panels with an integrated “DVI extension”. These make a cable
length of up to 50 meters possible.
DVI-D Interface
The DVI interface does not use VGA signals, so that the connection of CRT VGA monitors

LAN interface (X000/ X001)
The CX9020 systems have two switched LAN interfaces. Both ports are able to operate at speeds of 10 /
100 Mbit. The LEDs on the left-hand sides of the RJ45 sockets indicate the status of the LAN connection.
The upper LED indicates whether the port is connected to a network. The LED flashes if data traffic takes
place on the port (Link /Activity). The lower LED indicates the connection speed. The LED is off if the speed
is 10 Mbit. In 100 Mbit mode the LED is green.

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.

system
4.2.1.1
FUNCTION_BLOCK FB_S_UPS_CX9020_U900
The function block FB_S_UPS_CX9020_U900 can be used on CX devices with one-second UPS to control
the one-second UPS from the PLC. This allows the persistent data to be saved and a quick shutdown to be
performed in the event of a power failure. If possible the default values of the INPUTs of the
FB_S_UPS_CX9020_U900 should be retained.
Loss of data
Attention
The seconds UPS can be used only for a few seconds in the event of a power failure in order, to save persistent data. The data must be saved in the fast “persistent mode”
“SPDM_2PASS”, even though this can lead to real-time violations. Sufficient router memory
must be configured for the storage of the persistent data!
The second UPS does not have sufficient capacity for bridging power failures. Only the CFast card can be
used for data storage, in view of the fact that the UPS capacity is inadequate for operating a hard disk.
A QuickShutdown is performed automatically in the eSUPS_WrPersistData_Shutdown mode (standard
setting) after the storage of the persistent data.
In eSUPS_WrPersistData_NoShutdown mode only the persistent data are stored. No QuickShutdown is
executed.
In the eSUPS_ImmediateShutdown mode a QuickShutdown is executed immediately without saving data.
34
Version: 1.5
CX9020
Commissioning
In the eSUPS_CheckPowerStatus mode only a check is performed as to whether a power failure has
occurred. If this is the case, the module only switches back to the PowerOK state after the expiry of
tRecoverTime (10s).
Independent of the mode and thus independent of the saving or the shutting down of the controller, the UPS
switches the main board off after the capacitors have discharged, even if the voltage has returned in the
meantime.
Caution when using files:
If other applications or the PLC keep other files open or write to them, this can lead to faulty
files if the UPS switches off the controller.

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.
The CX unit recognizes these terminals automatically on scanning, reads out the terminal types and
automatically places them in the System Manager.

K-bus state
The K-bus status is saved in the state byte (see fig. K-bus interface “1”). If the value is 0 the K-bus is
operating synchronously and without errors. If the value is <> ”0” there may be a fault, or it may only be an
indication that the K-bus cycle is longer than the task, in which case it would no longer by synchronous with
the task. The task time should be faster than 100 ms. We recommend a task time of less than 50 ms. The Kbus update time typically lies between one and five ms.
Bit 0 = K-Bus error
Bit 1 = terminal configuration has changed since the start
Bit 2 = process image lengths do not match
Bit 8 = no valid inputs (yet)
Bit 9 = K-bus input update not yet complete
Bit 10 = K-bus output update not yet complete
Bit 11 = watchdog
Bit 15 = acyclic K-bus function active (e.g. K-bus reset)
If there is a K-bus error, this can be reset via the IOF_DeviceReset function block (in the TcIoFunctions.lib).

Disassembly and disposal
A CX9020 hardware configuration is dismantled in 2 stages:
1. Switching off and disconnecting the power supply
Before a CX9020 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 CX9020 hardware block should be removed from
the top-hat rail. Proceed as follows:
2.1. Release and remove the first Terminal next to the power supply unit on the tophat 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 CX9020 systems
To release the CX9020 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.
