The power supply terminal for the Embedded PC is located on the right-hand side. Bus Terminals (K-bus) or
EtherCAT Terminals (E-bus) can be attached on the right-hand side of the power supply terminal. The power
supply terminal automatically recognizes the respective bus system (K-bus or E-bus).

Software

In combination with the TwinCAT automation software, the CX52x0 Embedded PC becomes a powerful IEC
61131-3 PLC with up to four user tasks.

Additionally, Motion Control tasks can also be executed. It may be possible to control several servo axes,
depending on the required sampling time. In addition to simple point-to-point movements, it is possible to
execute more complex multi-axis functions such as electronic gearing, cam plate and flying saw.

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.

in advance and cannot be retrofitted to the device.

5.4.1 DVI-D (N010)

The DVI-D interface (X300) transfers digital data and is suitable for connection to digital displays. If the
optional N010 interface (DVI-D interface) is used, the first DVI-I interface can be operated either in VGA
mode or in DVI mode. 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.

6.1.5 Installing 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.20: 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.

6.2 Power supply

NOTE

Damage to the Embedded PCs

The Embedded PCs may be damaged during wiring.

• 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 "0V" 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.

Connections

No. Description

1 The upper spring-loaded terminals (Us) identified with "24V" and "0V" supply the

Embedded PC and the terminal bus (data transfer via K-bus or E-bus).

2 The 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

• When dimensioning the fuse for the system voltage (Us), observe the maximum power consumption of
the Embedded PC (see: Technical data)

• Protect the power contacts (Up) with a fuse with a max. rating of 10A (slow-blow).

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).

7.3.2 Searching for target systems

Before you can work with the devices, you must connect your local computer to the target device. Then you
can search for devices with the help of the IP address or the host name.

The local PC and the target devices must be connected to the same network or directly to each other via an
Ethernet cable. In TwinCAT a search can be performed for all devices in this way and project planning
subsequently carried out.

Prerequisites for this step:

• TwinCAT 3 must be in Config mode.

• IP address or host name of the device.

Search for the devices as follows:

1. In the menu at the top click on File > New > Project and create a new TwinCAT XAE project.

2. In the tree view on the left click on SYSTEM, and then Choose Target.

3. Click on Search (Ethernet).

4. Type the host name or the IP address of the device into the Enter Host Name / IP box and press
[Enter].

5. Mark the device found and click on Add Route.

The Logon Information window appears.

7.3.4 Configuring 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.29: Example configuration of a CX52x0 with EtherCAT cable redundancy.

Interference at the individual terminals is not intercepted by the cable redundancy.

Table27: Cable redundancy, hardware for sample configuration.

Type Description

CX2020 Embedded PC Is the EtherCAT master in the example.

Bus Coupler EK1110 EtherCAT extension can be used to extend an EtherCAT

segment by up to 100 m.

EK1100 Bus Coupler The Bus Coupler relays the EtherCAT signal to connected

EtherCAT Terminals.

EtherCAT Terminals Any number of EtherCAT Terminals can be connected to

the CX20x0 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:

http://www.beckhoff.de/forms/twincat3/warenkorb.aspx?lg=de&title=TS622x-EtherCAT­Redundancy&version=1.0.2

• 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.

Configure EtherCAT cable redundancy as follows:

CX52x0 49Version: 1.0

Configuration

1. In the tree view click on the EtherCAT master.

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.

CX52x050 Version: 1.0

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.

CX52x0 51Version: 1.0

Configuration

7.3.5 Using 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.

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)

8 1-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.

Fig.30: Behavior of systems in the event of a power failure without and with a 1-second UPS.

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 1MB 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 environment File path File name

TwinCAT 2 \\TwinCat\Boot\ TCPLC_T_x.wbp

TCPLC_T_x.wb~ (backup)

The x in the file name stands for
the number of the runtime system.

TwinCAT 3 \\TwinCat\3.1\Boot\Plc Port_85x.bootdata

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 CX52x0, check whether the 1-second UPS is activated or deactivated in the BIOS
(see: BIOS settings). Configure the Windows write filter and issue the corresponding write permissions
in order to be able to save persistent data (see: Windows write filter).

CX52x0 53Version: 1.0

1-second UPS (persistent data)

• Declare important data such as counter values in the PLC as VAR PERSISTENT. Then call the
function block FB_S_UPS_BAPI cyclically in TwinCAT in order to control the 1-second UPS (see:

FB_S_UPS_BAPI [}56]).

• Select the mode in the function block in order to specify what should happen in the case of a power
failure. Specify, for example, whether persistent data are saved and a quick shutdown is executed
(see: Mode and status of the function block).

• 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).

8.2 Windows 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.

The UWF does not need to be switched off, because an exception can be defined for the \boot directory.

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.31: 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.

CX52x0 55Version: 1.0

1-second UPS (persistent data)

8.3 FB_S_UPS_BAPI

The function block FB_S_UPS_BAPI can be used on devices with 1-second UPS and with BIOS-API from
version v1.15, in order to control the 1-second UPS from the PLC.

When the function block is first called, the data for accessing the 1-second UPS are determined via BIOS­API. This process takes several cycles. This is followed by cyclic testing for power failure. When the
persistent data are written next, the access data for the PLC are saved persistently, so that during
subsequent boot operations the check for power failures can take place immediately after the PLC start.

In the event of a power failure the charge state of the 1-second UPS is checked every 50ms, every 200ms
if voltage is present and the capacity is less than 90%, and every second if voltage is present and the
capacity is more than 90%. This also takes place via BIOS-API access.

In the event of a power failure the function block FB_S_UPS_BAPI can be used to save the persistent data
and/or execute a quick shutdown, depending on the selected mode. The default input values of the
FB_S_UPS_BAPI should be retained.

The 1-second UPS does not have sufficient capacity for bridging power failures. Only the Compact Flash/
CFast card/Micro SD can be used for data storage, in view of the fact that the UPS capacity is not sufficient
for operating a hard disk.

The 1-second 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. Make sure you configure adequate router memory for saving the persistent data.

Regardless of the mode and therefore irrespective of whether data were saved or a quick shutdown was
performed, the UPS switches off the mainboard after the capacitors have been discharged, even if the
voltage has returned in the meantime.

NOTE

Loss of data

If other applications or the PLC keep further files open or write to them, file errors may occur if the 1-second
UPS switches off the controller.

Function block modes

A QuickShutdown is performed automatically in the eSUPS_WrPersistData_Shutdown mode (standard
setting) after the storage of the persistent data.

In the eSUPS_WrPersistData_NoShutdown mode only the persistent data are saved, no QuickShutdown is
performed.

In eSUPS_ImmediateShutdown mode a quick shutdown is executed immediately, without saving data.

In the eSUPS_CheckPowerStatus mode only a check is performed as to whether a power failure has
occurred. If this is the case, the function block only switches back to the PowerOK state after the expiry of
tRecoverTime (10s).

8.5 Checking the validity of the variables

For TwinCAT 2 the implicit structure Systeminfotype.bootDataFlags can be read in order to determine the
validity of the persistent data (see: SYSTEMINFOTYPE [}59]).

For TwinCAT 3 the implicit variables PlcAppSystemInfo.BootDataLoaded and
PlcAppSystemInfo.OldBootData are available for determining the validity of the persistent data (see:
PlcAppSystemInfo).

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 number Description

0 RETAIN variables: LOADED (without error)

1 RETAIN variables: INVALID (the back-up copy was loaded, since no valid data was present)

2 RETAIN variables: REQUESTED (RETAIN variables should be loaded, a setting in TwinCAT

System Control)

4 PERSISTENT variables: LOADED (without error)

5 PERSISTENT variables: INVALID (the back-up copy was loaded, since no valid data was

present)

6 reserved

7 reserved

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 name Description

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.wbp RETAIN variables (x = number of the runtime system)

TCPLC_T_x.wbp PERSISTENT variables (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.

CX52x0 59Version: 1.0

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:

[HKEY_LOCAL_MACHINE\SOFTWARE\Beckhoff\TwinCAT\Plc]
"ClearInvalidRetainData"=dword:00000000
"ClearInvalidPersistentData"=dword:00000000

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.

HDD Read/Write CFast card

(red) Indicates access to the CFast card.

FB1 Status LED1 for fieldbus (the function is described under the fieldbus interface)

FB2 Status LED2 for fieldbus (the function is described under the fieldbus interface)

9.1.1 K-bus

The power supply unit checks the connected Bus Terminals for errors. The red LED "K-bus ERR" is off if no
error is present. The red LED "K-bus ERR" flashes if Bus Terminal errors are present.

Table28: Diagnostic LEDs in K-Bus mode.

Display LED Meaning

Us 24 V Power supply for basic CPU module. The LED lights green if the

power supply is correct.

Up 24V Power supply for terminal bus. The LED lights green if the power

supply is correct.

K-BUS RUN Diagnostic K-bus. The green LED lights up in order to indicate

fault-free operation. "Error-free" means that the communication
with the fieldbus system is also running.

K-BUS ERR Diagnostic K-bus. The red LED flashes to indicate an error. The

red LED blinks with two different frequencies.

The frequency and number of the flashes can be used to determine the error code and the error argument.
An error is indicated by the "K-bus ERR" LED in a particular order.

Table29: K-bus ERR LED, fault indication sequence through the LED.

Order Meaning

Fast blinking Starting the sequence

First slow sequence Error code

No display Pause, the LED is off

Second slow sequence Error code argument

Count how often the red LED K-bus ERR flashes, in order to determine the error code and the error
argument. In the error argument the number of pulses shows the position of the last Bus Terminal before the
error. Passive Bus Terminals, such as a power feed terminal, are not included in the count.

overvoltage peaks.

• Implement EMC measures.

• If a K-bus error is present, it can be
localized by a restart of the power supply
(by switching it off and then on again)

• One of the Bus Terminals is defective;
halve the number of Bus Terminals
attached and check whether the error is
still present with the remaining Bus
Terminals. Repeat this procedure until
the faulty Bus Terminal has been found.

Check whether the Bus End Terminal 9010

(switch off and back on again).

(switch off and back on again).

Check the configuration and the Bus

Terminals for consistency.

For some error the LED "K-BUS ERR" does not go out, even if the error was rectified. Switch the power
supply for the power supply unit off and back on again to switch off the LED after the error has been rectified.

CX52x0 63Version: 1.0

Error handling and diagnostics

State variable

In TwinCAT there is a State variable under the Bus Coupler for K-bus diagnostics.

Fig.32: Status variable for error handling and diagnostics under TwinCAT.

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.

Table31: Description of the State variable values.

Bit Description

Bit 0 K-bus error.

Bit 1 Terminal configuration has changed since the start.

Bit 2 Process image lengths do not match.

Bit 8 (still) no valid inputs.

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).
