2.1Intended use
The CX51x0 Embedded PC is a control system and is intended for mounting on a DIN rail in a control
cabinet or terminal box. The Embedded PC series is used in conjunction with Bus Terminals for recording
digital or analog signals from sensors and transferring them to actuators or higher-level controllers.
The Embedded PC is designed for a working environment that meets the requirements of protection class
IP20. This involves finger protection and protection against solid foreign objects up to 12.5 mm, but not
protection against water. Operation of the devices in wet and dusty environments is not permitted, unless
specified otherwise. The specified limits for electrical and technical data must be adhered to.
Potentially explosive atmospheres
Device modification CX2900-0107 is mandatory for operation of the Embedded PC in potentially explosive
atmospheres, zone 2/22. The device modification includes a factory-installed retainer bracket for
mechanically securing the plug connectors.
The device modification is mandatory for operating the Embedded PC in the following potentially explosive
atmospheres:
1. For Zone 2 atmospheres in which gas is present as a combustible material. Zone 2 means that an explosive atmosphere does usually not occur during normal operation, or only for a short time.
2. For Zone 22 atmospheres in which dust is present as a combustible material. Zone 22 means that an
explosive atmosphere in the form of a cloud does usually not occur during normal operation, or only
for a short time.
The Embedded PC must be installed in a housing, which ensures protection class IP 54 for gas according to
EN 60079-15. A housing with protection class IP 54 is required for non-conductive dust. IP 6X is required for
conductive dust according to EN 60079-31.
Improper use
The Embedded PC is not suitable for operation in the following areas:
• In potentially explosive atmospheres, the Embedded PC may not be used in other zones except for
2/22 and not without a suitable housing.
• Areas with an aggressive environment, e.g. aggressive gases or chemicals.
• Living areas. In living areas, the relevant standards and guidelines for interference emissions must be
adhered to, and the devices must be installed in housings or control boxes with suitable attenuation of
shielding.

2.2Staff qualification
All operations involving Beckhoff software and hardware may only be carried out by qualified personnel with
knowledge of control and automation engineering. The qualified personnel must have knowledge of the
administration of the Industrial PC and the associated network.
All interventions must be carried out with knowledge of control programming, and the qualified personnel
must be familiar with the current standards and guidelines for the automation environment.
2.3Safety instructions
The following safety instructions must be followed during installation and working with networks and the
software.
Explosion protection
Device modification CX2900-0107 is mandatory for operation of the Embedded PC in potentially explosive
atmospheres, zone 2/22. The device modification entails the modification and relocation of the device label
and a factory-fitted retainer bracket for mechanically securing the connectors.
WARNING
Operation without device modification
Without the CX2900-0107 device modification, the USB plug connectors may slip out of the USB ports due
to vibration, which may trigger a deflagration or explosion.
The Embedded PC must only be used with the device modification, and the USB plug connectors must be
secured to the retainer brackets with cable ties.
Tighten the screws of the DVI plug connector and, if present, also the screws of the fieldbus plug connectors,
in order to prevent the plug connectors slipping out. Only use RJ45 connectors with an intact latch. Use
cable ties to secure the USB plug connectors and RJ45 connectors to the retainer brackets.
The CXxxxx-N020 optional interface (audio interface) may not be used in potentially explosive atmospheres.
The Embedded PC must be installed in a housing, which ensures protection class IP54 for gas according to
EN 60079-15. A housing with protection class IP54 is required for non-conductive dust. IP6X is required for
conductive dust according to EN 60079-31.
Observe the temperature at the cable entry points into the housing. If the temperature during nominal
operation is higher than 70 °C at the entry points or higher than 80 °C at the wire branching points, cables
must be selected that are designed for these high temperatures and operation in potentially explosive
atmospheres.
Maintain the prescribed ambient temperature during operation. The permissible ambient temperature lies
within the range from 0 °C ... +60 °C.
Take measures to prevent the rated operating voltage exceeding 119 V through short-term interference
voltages.
Switch off the power supply and ensure that no explosive atmosphere occurs when:
• Bus Terminals are connected or removed,
• the Embedded PC is wired or cables are connected,
• the front flap is opened,
• the CFast card, MicroSD card or battery is replaced.

6.1.5Installing passive EtherCAT Terminals
Incorrectly installed passive EtherCAT Terminals
The E-bus signal between an Embedded PC and the EtherCAT Terminals can be impaired due to
incorrectly installed passive EtherCAT Terminals.
Passive EtherCAT Terminals should not be installed directly on the power supply unit.
EtherCAT Terminals that do not take part in active data exchange are referred to as passive terminals.
Passive EtherCAT Terminals have no process image and do not require current from the terminal bus (Ebus).
Passive EtherCAT Terminals (e.g. EL9195) can be detected in TwinCAT. In the tree structure the EtherCAT
Terminal is displayed without process image, and the value in column “E-bus (mA)” does not change,
compared to the preceding EtherCAT Terminal.
Fig.24: Identifying a passive EtherCAT Terminal in TwinCAT.
The entry "Current consumption via E-Bus" in the technical data of an EtherCAT Terminal indicates whether
a particular EtherCAT Terminal requires power from the terminal bus (E-bus).
The following diagram shows the permissible installation of a passive EtherCAT Terminal. The passive
EtherCAT Terminal was not directly attached to the power supply unit.
• The cables for the power supply should only be connected in de-energized state.
The power supply terminals require an external voltage source, which provides 24 V DC (-15% / +20%). The
power supply terminal must provide 4 A at 24 V, in order to ensure the operation of the Embedded PCs in all
situations.
The cabling of the Embedded PC in the control cabinet must be done in accordance with the standard EN
60204-1:2006 PELV = Protective Extra Low Voltage:
• The "PE" and "0V" conductors of the voltage source for a basic CPU module must be on the same
potential (connected in the control cabinet).
• Standard EN 60204-1:2006, section 6.4.1:b stipulates that one side of the circuit, or a point of the
energy source for this circuit must be connected to the protective earth conductor system.
Connection example
Table26: Legend for the connection example
No.Description
1The upper spring-loaded terminals (Us) identified with “24 V“ and “0 V“ supply the
Embedded PC and the Terminal Bus (data transfer via K- or E-bus).
2The spring-loaded terminals (Up) identified as "+", "-" and "PE" supply the Bus Terminals
via the power contacts and the sensors or actuators connected to the Bus Terminals.
Fuse protection
• When dimensioning the fuse for the system voltage (Us), observe the max. power consumption of the
Embedded PC (see: Technical Data [}87]).
• Protect power contacts (Up) with a fuse of max. 10 A (slow blow).

• The red LED (Up) indicates the Bus Terminal supply via the power
contacts.
NOTE
Interrupting / switching off the power supply
To switch off the Embedded PC, do not disconnect the ground (0 V), because otherwise current may continue to flow via the shielding, depending on the device, and damage the Embedded PC or peripheral devices.
• Always disconnect the 24 V line. Devices connected to the Embedded PC, which have their own power
supply (e.g. a Panel) must have the same potential for "PE" and "0 V" as the Embedded PC have (no
potential difference).
Observe the UL requirements
The CX51x0 Embedded PCs are UL certified. The corresponding UL label can be found on the type plate.
Fig.27: UL label for CX51x0 Embedded PC.
The CX51x0 Embedded PCs can thus be used in areas in which special UL requirements have to be met.
These requirements apply to the system voltage (Us) and to the power contacts (Up). Application areas
without special UL requirements are not affected by UL regulations.
UL requirements
• The Embedded PCs must not be connected to unlimited voltage sources.
• Embedded PCs may only be supplied from a 24 V DC voltage source. The voltage source must be
insulated and protected with a fuse of maximum 4 A (corresponding to UL248).
• Or the power supply must originate from a voltage source that corresponds to NEC class 2. An NEC
class 2 voltage source must not be connected in series or parallel with another NEC class 2 voltage
source.

7.5.5Configuring EtherCAT cable redundancy.
The Embedded PC has two independent Ethernet interfaces, which can be used for EtherCAT cable
redundancy. Cable redundancy offers resilience for the cabling. Interruptions of the EtherCAT
communication due to broken wires or unplugged LAN cables are avoided.
Fig.33: Smallest possible configuration for EtherCAT cable redundancy.
Interference at the individual terminals is not intercepted by the cable redundancy.
Table32: Cable redundancy, hardware for sample configuration.
TypeDescription
CX51x0 Embedded PCIs the EtherCAT master in the example.
Bus Coupler EK1110EtherCAT extension can be used to extend an EtherCAT
segment by up to 100 m.
EK1100 Bus CouplerThe Bus Coupler relays the EtherCAT signal to connected
EtherCAT Terminals.
EtherCAT TerminalsAny number of EtherCAT Terminals can be connected to
the CX51x0 Embedded PC and the Bus Coupler.
Requirements:
• For TwinCAT 2 you have to install and license the supplement TS622x | TwinCAT EtherCAT
Redundancy on the Embedded PC:
• In TwinCAT 3 the supplement is already included and only has to be licensed.
• Hardware wired as EtherCAT ring (see Fig.: Smallest possible configuration for EtherCAT cable
redundancy) and added in TwinCAT.
CX51x064Version: 2.7
Configure EtherCAT cable redundancy as follows:
1. In the tree view click on the EtherCAT master.
Configuration
2. Click on the EtherCAT tab, then Advanced Settings.
3. Click on Redundancy in the tree structure on the left.
4. Click on the option Second adapter, followed by the Search button.
CX51x065Version: 2.7
Configuration
5. Select the appropriate LAN connection according to your cabling at the Embedded PC.
6. Confirm the settings with OK.
ð You have successfully configured cable redundancy. Under the Online tab the EtherCAT slaves are
displayed, for which cable redundancy was configured.
Under State the state of the individual EtherCAT slaves is displayed. If, for example, the cable
connection between the EK1100 and EK1110 Bus Couplers is interrupted, the status of the Bus Coupler
changes. The message "LINK_MIS B" and "LINK_MIS A" appears under status.
Although the connection between the Bus Couplers is interrupted, the EtherCAT Terminals connected to
the EK1100 Bus Coupler show no fault.
If the cable connection is interrupted without cable redundancy at the same location, the terminals show
a fault under status.
7.5.6Using a hardware watchdog
The function block FB_PcWatchdog_BAPI activates a hardware watchdog on the Embedded PC. The
watchdog can be used to automatically restart systems that have entered an infinite loop or where the PLC
has stopped.
The watchdog is activated with bExecute = TRUE and nWatchdogTimeS >= 1s.
Once the watchdog has been activated, the function block must be called cyclically and at shorter intervals
than nWatchdogTimeS, because the Embedded PC automatically restarts if the set time is less than
nWatchdogTimeS.
CX51x066Version: 2.7
Configuration
NOTE
Unwanted restart
The watchdog restarts the Embedded PC as soon as the time set for nWatchdogTimeS elapses.
Be aware of this behavior and disable the watchdog if you use breakpoints, carry out a PLC reset or an
overall reset, stop TwinCAT, switch to config mode or activate the configuration.
Requirements:
• Tc2_System library.
• TwinCAT v3.1.0
• A previously created PLC project in TwinCAT.
Locating the function block in TwinCAT:
1. Double-click on Tc2_System in the tree view under PLC > PLC project > References.
The Library Manager appears.
2. Under Tc2_System > POUs > SYSTEM +TIME click on the function block FB_PcWatchdog_BAPI.
ð The description of the function block can then be found under the Documentation tab or in the library
description under: FB_PcWatchDog_BAPI. If necessary, you can install the Tc2_System library at a
later stage via the Add Library button in the Library Manager.

1-second UPS (persistent data)
81-second UPS (persistent data)
Loss of data
The use of the 1-second UPS outside of the documented possibilities can lead to loss or corruption
of data.
Use only TwinCAT to control the 1-second UPS and save only persistent data with a maximum size
of 1 MB.
The 1-second UPS is an UltraCap capacitor that continues to
supply the processor with power in the event of a power failure.
During this period persistent data can be saved, which are
available on switching on again.
Since the 1-second UPS is designed for the entire service life,
the holding time is considerably longer with new devices. The
capacitors age over the course of time and the holding time
decreases. Therefore a maximum of 1MB persistent data can
be reliably saved over the entire service life.
Do not save any other data and do not use any other
applications to control the 1-second UPS.
Please note that the 1-second UPS does not supply power to the K-bus or the E-bus and that their data may
already be invalid when the 1-second UPS is activated. Also, the fieldbus system (or Ethernet) may not work
or not work properly once the 1-second UPS was activated.
Storage location and names of the files:
The persistent data are saved by default in the TwinCAT boot directory:
Development environmentFile pathFile name
TwinCAT 2\\TwinCat\Boot\TCPLC_T_x.wbp
TwinCAT 3\\TwinCat\3.1\Boot\PlcPort_85x.bootdata
TCPLC_T_x.wb~ (backup)
The x in the file name stands for the number
of the runtime system.
Port_85x.bootdata-old (backup)
The x in the file name stands for the number
of the runtime system.
Configure the 1-second UPS as follows in order to save persistent data:
• In the case of the CX51x0, check whether the 1-second UPS is activated or deactivated in the BIOS
(see: BIOS settings [}69]). Configure the Windows write filter and issue the corresponding write
permissions in order to be able to save persistent data (see: Windows write filter).
• Declare important data such as counter values in the PLC as VAR PERSISTENT. Then call the
function block FB_S_UPS_CX51x0 cyclically in TwinCAT in order to control the 1-second UPS (see:
FB_S_UPS_CX51x0 [}72]).
• Select the mode in the function block in order to specify what should happen in the case of a voltage
failure. Specify, for example, whether persistent data are saved and a quick shutdown is executed
(see: Mode and status of the function block [}74]).
• Subsequently you can check the validity of the variables and monitor whether the persistent variables
are loaded without error (see: Checking the validity of the variables [}75]).

Integration into a PLC
TwinCAT offers special function blocks for integrating the S-UPS into a PLC program. These are described
below. From TwinCAT 2.11R3 Build 2247 or TwinCAT 3.1 Build 4018 the required library is integrated in the
installation. For older versions the library:
https://infosys.beckhoff.com/content/1033/CX51x0_HW/Resources/rar/1941420683.rar
has to be copied into the TwinCAT library directory.
CX51x070Version: 2.7
1-second UPS (persistent data)
8.2Windows write filter
Since the persistent data are stored on a storage medium, the file and the path must be writeable. If you use
the Windows write filter, the Windows partition is protected against write access operations, and the
persistent data are not saved.
• Switch off the EWF, if you want to save persistent data.
• The FBWF and UWF do not have to be switched off, because an exception can be defined for the
directory \Boot.
For Windows CE and Windows Embedded Compact 7 no Windows write filters are used.
FBWF exception list
By default an exception list is automatically created when the FBWF is switched on. The \Boot directory is
already entered in this list. Check the configuration of the FBWF if you have made changes to the exception
list.
Fig.34: FBWF exception list, under TwinCAT 2 (left) and TwinCAT 3.
The persistent data are saved by default under \TwinCAT\Boot in TwinCAT 2 and under \TwinCAT\3.1\Boot
in TwinCAT 3.
The FBWF can be configured via the Beckhoff FBWF manager.
UWF exception list
By default an exception list is automatically created when the UWF is switched on. The \Boot directory is
already entered in this list. Check the configuration of the UWF if you have made changes to the exception
list.
Fig.35: UWF exception list under TwinCAT 3
By default, the persistent data are stored under \TwinCAT\3.1\Boot in TwinCAT 3.
The UWF can be configured via the Beckhoff Unified Write Filter Manager.
CX51x071Version: 2.7
1-second UPS (persistent data)
8.3FB_S_UPS_CX51x0
Loss of data
The 1-second UPS switches the mainboard off as soon as the capacitors have discharged.
If other applications or the PLC are keeping other data open or are writing to them, data may be
corrupted or lost.
In the case of the CX51x0 the function block FB_S_UPS_CX51x0 is used to control the 1-second UPS from
the PLC. If possible, use the standard values of the FB_S_UPS_CX51x0 and call the function block cyclically
in the PLC.
The function block has various modes that control the behavior of the Embedded PC when the 1-second
UPS is triggered:
Table33: Block modes.
ModeFunction
eSUPS_WrPersistData_ShutdownWriting of the persistent data, followed by
quick shutdown.
eSUPS_WrPersistData_NoShutdownOnly writing of the persistent data (no
quick shutdown)
eSUPS_ImmediateShutdownQuick shutdown only (no writing of
persistent data)
eSUPS_CheckPowerStatusMonitoring only (neither writing of the
persistent data nor quick shutdown); data
handling is entirely up to the user.
Regardless of the mode and therefore irrespective of whether data were saved or quick shutdown was
performed, the 1-second UPS switches off the mainboard after discharging of the capacitors, even if the
voltage has returned in the meantime.

For TwinCAT 2 the implicit structure Systeminfotype.bootDataFlags can be read in order to determine the
validity of the persistent data (see: SYSTEMINFOTYPE [}75]).
For TwinCAT 3 the implicit variables PlcAppSystemInfo.BootDataLoaded and
PlcAppSystemInfo.OldBootData are available for determining the validity of the persistent data (see:
runTimeNo: specifies the number of the runtime system (1..4).
projectName: project name as STRING.
numberOfTasks: number of tasks contained in the runtime system (max. 4).
onlineChangeCount: number of online changes since the last complete download.
bootDataFlags: State of the boot data (RETAIN and PERSISTENT) after loading. The upper four bits
indicate the state of the persistent data, while the lower four bits indicate the state of the retain data.
Bit numberDescription
0RETAIN variables: LOADED (without error)
1RETAIN variables: INVALID (the back-up copy was loaded, since no valid data was present)
2RETAIN variables: REQUESTED (RETAIN variables should be loaded, a setting in TwinCAT

4PERSISTENT variables: LOADED (without error)
5PERSISTENT variables: INVALID (the back-up copy was loaded, since no valid data was
present)
6reserved
7reserved
systemStateFlags : Reserved.
When shutting TwinCAT down the PERSISTENT and RETAIN data is written into two files on the hard disk.
The path can be specified in TwinCAT System Control by means of the TwinCAT system properties (PLC
tab). The standard setting is "<Drive>:\TwinCAT\Boot". The files all have a fixed name with fixed extensions:
File nameDescription
TCPLC_P_x.wbp Boot project (x = number of the run-time system)
TCPLC_S_x.wbp Packed source code (x = number of the runtime system)

TCPLC_R_x.wb~ Backup copy of the RETAIN variables (x = number of the runtime system)
TCPLC_T_x.wb~ Backup copy of the PERSISTENT variables (x = number of the runtime system)
If the persistent or retain variables are not loaded, e.g. because they are invalid, the backup file is loaded by
default. In that case bit 1 of the bootDataFlags (for the RETAIN variables) in the PLC and/or bit 5 (for the
PERSISTENT variables) is set.
CX51x075Version: 2.7
1-second UPS (persistent data)
A registry setting can be used to determine whether the backup file is deleted or used. The backup file is
used by default (setting 0). If the backup file is to be deleted, the value of "ClearInvalidRetainData" or
"ClearInvalidPersistentData" must be set to 1 in the registry under:
the value of "ClearInvalidRetainData" or of "ClearInvalidPersistentData" must be set to 1.
Whether the backup file is to be used can also be set in the TwinCAT System Manager in the tree structure
on the left under PLC > PLC Settings:
The backup files are deleted if the option Clear Invalid Retain Data or Clear Invalid Persistent Data is set
in the System Manager. Corresponds to registry entry 1.

If the value is "0", the K-bus operates synchronous and without error. 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 be synchronous with the task. The task time should be faster than 100 ms. We recommend a task
time of less than 50 ms. The K-bus update time typically lies between one and five ms.
Table36: Description of the State variable values.
