Product overview
4.5 Architekture overview
The Embedded PCs of the CX20x0 family all have the same architecture. The architecture is described
below.
Fig.5: CX20x0 architecture overview.
The CX20x0 Embedded PCs are based on the Sandy Bridge microarchitecture developed by Intel. The
following CPUs are used:
• Intel®Celeron® 827E (Singlecore),
• Intel®CORETM i7 2610UE (Dualcore),
• and Intel®CoreTM i7 2715QE (Quadcore).
In addition to the arithmetic unit, the CPU also contains the memory controller and the graphics controller.
The single-core processor uses the Intel® HD has as graphics core. The two Core
TM
i7 CPUs (dual or quad
core) feature an Intel® HD graphics 3000 core. This offers a somewhat higher performance than the Intel
HD graphics core, and the quad core offers a higher clock speed. For details on the CPUs please refer to
Intel. The memory is connected directly to the memory controller. The Embedded PCs are available in two
memory configurations: 2GB or 4GB DDR3 RAM. The memory is not expandable and must be ordered ex
factory.
All CX20x0 Embedded PCs use the Mobile Intel® QM67 Express chipset (Intel® BD82QM67 PCH). This
chip provides all required interfaces:
• 4 x USB 2.0

6.2.6 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.

6.3 Connecting the 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 units require an external voltage source, which provides 24 V DC (-15% /+20%).
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 with CX2020 basic CPU module and CX2100-0004 power supply unit:
Table27: Legend for the connection example.
No. Description
1 The upper spring-loaded terminals identified with "24V" and "0V" supply the basic CPU
module and the terminal bus (data transfer via K- or E-bus).
2 The spring-loaded terminals identified as "+", "-" and "PE" supply the Bus Terminals via
the power contacts and the sensors or actuators connected to the Bus Terminals.

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).

7.5.5 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.

NOVRAM
8 NOVRAM
The NOVRAM can be used to reliably save important variable values, such as production data or counter
values, in the event of a power failure. The memory size of the NOVRAM is limited and only suitable for
smaller data quantities up to 63 kB.
This chapter illustrates how the NOVRAM is
• used in TwinCAT 3 (see: Use under TwinCAT 3 [}62]).
Functioning
The NOVRAM (Non-Volatile Random Access Memory) is a special memory component that is used to
reliably save important data. The NOVRAM consists of two sections, a volatile memory and a non-volatile
memory.
TwinCAT only writes to the volatile section of the NOVRAM. In the event of a power failure, the data are
automatically copied from the volatile memory into the non-volatile memory. The energy required for this
process is supplied by a capacitor. As soon as the power supply is restored, the data are automatically
copied back into the volatile memory, so that TwinCAT can continue to use them.
Fig.35: Controller behavior with and without NOVRAM.
Memory size
The NOVRAM has a capacity of 128 kB. However, for reasons of data consistency, effectively less than 63
kB of data can be securely saved in the NOVRAM. The data are saved cyclically and alternately based on
the dual buffer principle, in order to avoid the risk of data inconsistency.

NOVRAM
8.1 Use under TwinCAT 3
Under TwinCAT 3 (from Build 4020) a delta algorithm is used to save data in the NOVRAM. The algorithm
does not save all the variables in the NOVRAM. Instead, it searches for changes (delta function) compared
to the previous cycle and only saves variables that have changed.
To use the delta algorithm, a Retain Handler must be created in TwinCAT 3, and the relevant variables must
be declared in the PLC with the keyword VAR_RETAIN.
A new feature of this method is that no function blocks have to be used. The Retain Handler saves data in
the NOVRAM in the event of a power failure and makes them available again once the power has been
restored.
8.1.1 Creating a Retain Handler
This chapter describes how to create a Retain Handler in TwinCAT 3. The Retain Handler saves data in the
NOVRAM and makes them available again. In other words, important variable values such as production
data or counter values are retained during a restart or power failure.
Prerequisites for this step:
• TwinCAT 3.1 Build: 4020.
• A target device selected in TwinCAT.
Create the Retain Handler as follows:
1. Right-click on Devices in the tree view on the left-hand side.
2. In the context menu click on Scan.
3. Select Device (NOV-DP-RAM) and confirm with OK.

save them in the NOVRAM.
The following diagrams provide an overview of how long the Retain Handler needs to save a particular data
quantity in the NOVRAM. Use the diagrams to select your task cycle time such that a particular data quantity
is saved in the NOVRAM within the selected task cycle time.

8.1.4 Deleting variables under the Retain Handler
If variables are deleted from the PLC, the link with the Retain Handler is cancelled. However, the variables
continue to be shown under the Retain Handler and are not deleted automatically.
Under TwinCAT 3 the variables have to be deleted manually.
Prerequisites for this step:
• Variables declared with VAR_RATAIN were deleted from the PLC.
Delete the variables under the Retain Handler as follows:
1. The variable GVL_Retain.iNt under the Retain Handler is to be deleted.
2. Right-click on the Retain Handler in the tree view on the left.
3. In the context menu click on Optimize Retain Variables.
ð The variable under the Retain Handler is deleted.

UPS (persistent data)
9 UPS (persistent data)
If the power supply fails, the UPS continues to supply the Embedded PC. During this period persistent data
can be saved, which are available on switching on again. Use a UPS to shut down the Embedded PC in a
controlled manner and to save persistent data.
The following UPS configurations can be used:
• CX2100-0904, power supply unit with integrated capacitive UPS.
• CX2100-0914 power supply unit and CX2900-0192 battery pack.
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 C:\TwinCAT\Boot\ TCPLC_T_x.wbp
TwinCAT 3 C:\TwinCAT\3.1\Boot\ Port_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 CX20x0 as follows in order to save persistent data:
• First of all you have to configure the UPS. Read how to do this in the relevant chapter of the
CX2100-09x4 power supply documentation.
https://download.beckhoff.com/download/document/ipc/embedded-pc/embedded-pc-cx/
cx2100-09x4de.pdf
• Configure the Windows write filter and issue the corresponding write permissions in order to be able to
save persistent data (see: Windows write filter [}69]).
• Declare important data such as counter values in the PLC as VAR PERSISTENT.
• Subsequently you can check the validity of the variables and monitor whether the persistent data are
loaded without error (see: Checking the validity of the variables [}70]).

UPS (persistent data)
9.1 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.
• 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.38: 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.39: 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.

9.2 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 [}70]).
For TwinCAT 3 the implicit variables PlcAppSystemInfo.BootDataLoaded and
PlcAppSystemInfo.OldBootData are available for determining the validity of the persistent data (see:
PlcAppSystemInfo).

END_TYPE
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)
3 reserved
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.
CX20x070 Version: 2.5
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.

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.
State variable
In TwinCAT there is a State variable under the Bus Coupler for K-bus diagnostics.
CX20x0 73Version: 2.5
Error handling and diagnostics
Fig.40: 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.
