Product overview
CX8100 designates a product family of Embedded PCs based on a 32-bit ARM CPU. The CX8100 Embedded PC is programmable and is able to execute its own control program. In addition to that the Embedded PC acts as a slave device of a higher-level fieldbus system.
The CX8100 Embedded PC has the following basic configuration:
· a 512 MB MicroSD card, · an Ethernet interface · as well as two switched Ethernet interfaces (2 x RJ45, switched).
You can use the CX8100 Embedded PCs as decentralized controllers and in this way ensure that the local program continues to be executed on the CX8100 in the event of an interruption in the higher-level fieldbus system.
The operating system is Microsoft Windows Embedded Compact 7. Because there is no monitor port, the operating system and its "virtual" display can only be accessed via the network. Beckhoff Device Manager and Remote Display (Cerhost)
The Embedded PC features an internal 1-second UPS as persistent data memory. The 1-second UPS enables persistent data to be saved to the MicroSD card in the event of a power failure.
Power supply terminal
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).
The use of EtherCAT Terminals (E-bus) enables further options, such as the implementation of different topologies, the integration of further bus systems such as CANopen, PROFIBUS and PROFINET and with the EtherCAT Box Modules connection to the IP67 world.
Fieldbus interface
CX8100 devices are being prepared for further fieldbus systems such as EtherCAT (slave), PROFINET, EtherNet/IP, CANopen, PROFIBUS and other communication systems.
Available fieldbus systems: · CX8110: EtherCAT · CX8180: RS232/485 · CX8190: Ethernet (Realtime Ethernet, ADS UDP, ADS TCP, EAP, Web Services) · CX8191: BACnet (client and server)
Programming
The CX8100 Embedded PCs are programmed according to the high-performance IEC 61131-3 standard. The TwinCAT 3 automation software forms the basis for the programming of the Embedded PC.
Configuration
The CX8100 Embedded PC is commissioned via the Ethernet interface. The fieldbus interface and all connected devices such as EtherCAT Terminals or Bus Terminals are then read out via TwinCAT 3. The configuration is stored on the Embedded PC after the parameterization. The configuration thus created can be accessed again later.
The shortest usable task time is 500 µs, although this is only achievable with a very small system load. A task time of 1 to 50 ms is recommended for the I/O data. Other tasks can also be set slower. When using shorter cycle times, the total system load is to be observed.

Product overview
Transmission standards
10Base5 The transmission medium for 10Base5 consists of a thick coaxial cable ("yellow cable") with a max. transmission speed of 10 Mbaud arranged in a line topology with branches (drops) each of which is connected to one network device. Because all the devices are in this case connected to a common transmission medium, it is inevitable that collisions occur often in 10Base5.
10Base2 10Base2 (Cheaper net) is a further development of 10Base5, and has the advantage that the coaxial cable is cheaper and, being more flexible, is easier to lay. It is possible for several devices to be connected to one 10Base2 cable. It is frequent for branches from a 10Base5 backbone to be implemented in 10Base2.
10BaseT Describes a twisted pair cable for 10 Mbaud. The network here is constructed as a star. It is no longer the case that every device is attached to the same medium. This means that a broken cable no longer results in failure of the entire network. The use of switches as star couplers enables collisions to be reduced. Using full-duplex connections they can even be entirely avoided.
100BaseT Twisted pair cable for 100 MBaud. It is necessary to use a higher cable quality and to employ appropriate hubs or switches in order to achieve the higher data rate.
10BaseF The 10BaseF standard describes several optical fiber versions.
Short description of the 10BaseT and 100BaseT cable types Twisted pair copper cable for star topologies, where the distance between two devices may not exceed 100 meters.
UTP Unshielded twisted pair This type of cable belongs to category 3, and is not recommended for use in an industrial environment.
S/UTP Screened/unshielded twisted pair (screened with copper braid) Has a general screen of copper braid to reduce influence of external interference. This cable is recommended for use with Bus Couplers.
FTP Foiled shielded twisted pair (screened with aluminum foil) This cable has an outer screen of laminated aluminum and plastic foil.
S/FTP Screened/foiled-shielded twisted pair (screened with copper braid and aluminum foil) Has a laminated aluminum screen with a copper braid on top. Such cables can provide up to 70 dB reduction in interference power.

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 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.

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 CX8190 Embedded PCs are UL certified. The corresponding UL label can be found on the type plate.
The CX8190 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.

Operating system
The Microsoft Windows Embedded Compact 7 operating system is used on the CX8190 Embedded PC. This operating system is optimized for the CX8190 Embedded PC. This means that not all features of Windows Embedded Compact 7 are available.
Security
For reasons of security the CERHOST and TELNET services are deactivated in the delivery state. To reactivate these services, you need a MicroSD card reader.
CERHOST
CERHOST is deactivated by current images on first start-up via the registry file CeRemoteDisplay_Disable.reg, which is located in the folder RegFiles.
To reactivate CERHOST you have to delete the file CeRemoteDisplay_Disable.reg from the folder RegFiles and also the folder Documents and Settings
Then reinsert the MicroSD card in the Embedded PC and reboot. The Embedded PC creates a new Document and Settings directory and then reboots automatically.
The Embedded PC is then accessible again via CERHOST.
TELNET
TELNET is deactivated by current images on first start-up via the registry file Telnet_Disable.reg, which is located in the folder RegFiles.
To reactivate TELNET you have to delete the file Telnet_Disable.reg from the folder RegFiles and also the folder Documents and Settings.
Then reinsert the MicroSD card in the Embedded PC and reboot. The Embedded PC creates a new Document and Settings directory and then reboots automatically.

6.1.3 FTP Server
Restricted access through firewall
From image version "CX8100_WEC7_LF_v604h_TC31_B4022.20", the firewall for the CX8190 is enabled by default. This means that a passive FTP connection (as used by Microsoft, for example) cannot be established. We therefore recommend using active FTP access. Enter TCP ports 20 and 21 in the firewall.
The File Transfer Protocol (FTP) is based exclusively on TCP-based communication connections. FTP specifies two TCP ports, which are important for data transfer:
· Port 20/tcp: This port is also referred to as data port and is used to send/receive files and directory lists.
· Port 21/tcp: This port is generally referred to as command port and is used to exchange status information between the client and server.
Separate TCP connections are used for sending and receiving files (data port) and for transmitting commands (command port). With FTP, two connection modes are available for setting up such connections: "Active FTP" and "Passive FTP". Depending on the connection mode, the two ports mentioned above are initiated differently, which is described in more detail below.
Active FTP
With active FTP, the client connects to the command port of the FTP server. The client uses a random port N, e.g. 4242/tcp, as source port. The client then listens on port N+1 and notifies the server of this port. The server then connects to the client on port N+1 and uses its data port as the source port.
A problem with active FTP is that the client itself does not establish a connection to the server's data port, but communicates a port (N+1) to the server, which then connects to the client via its data port. In the case of firewalls or NAT devices that are located upstream of the client, this could involve additional configuration effort on the client side, since the data port of the client behind the firewall must be accessible to the server (see figure "Connect 4243").
Passive FTP
This method is used when the client is not directly accessible by the server. This is the case, for example, if the client is behind a firewall that uses NAT to rewrite the client's address. With passive FTP, the FTP client initiates a connection via two random TCP ports N (command port) and N+1 (data port). The first port is used to connect to the server's command port. However, instead of the client communicating its port N+1 to the server so that the server can open a connection to it (see active FTP), the client first transmits a so-called PASV command. The server now knows that the connection is via passive FTP. As a result, the server opens a (random) port P as data port and transmits it to the client. The client then initiates a connection with port P and uses port N+1 (data port) as the source port. This connection is then used to transfer the data.
28
Version: 1.4
CX8190
Configuration
On closer examination it becomes apparent that the firewall problem of active FTP is reversed with passive FTP. On the server side, the firewall should be configured such that the data port of the server can be reached by the client. Many FTP servers offer the option to configure the data ports to be used.

IP address
6.2.1 Setting with DIP switches
You can set the IP address for the switched Ethernet interfaces X101/X102 with the DIP switches S101. The DIP switches have no meaning for the Ethernet interface X001.
Fig. 8: DIP switch S101, switches 1 to 10.
Right switch position: on "1". Left switch position: off "0". You can edit the last byte of the IP address with DIP switches 1 to 8. The DIP switches take priority over the settings in the operating system. The changes are only accepted after restarting the Embedded PC. Table 8: Meaning of the DIP switch S101.
DIP switch S101 10 on and 9 off. 10 off and 9 off.
10 off and 9 off 1 to 8 all on
Meaning DHCP active. Standard setting ex factory. The DIP switches 1 to 8 then have no meaning. DHCP inactive.
The fixed IP address 192.168.1.xxx and subnet mask 255.255.255.0 are used as standard.
The last byte of the IP address 192.168.1.xxx is edited with DIP switches 1 to 8.
You can change the first three bytes of the IP address in the operating system [} 31] or via the web interface (Beckhoff Device Manager) [} 34]. You can edit the last byte of the IP address again with the DIP switches. The complete IP address is adopted from the operating system or the web interface (Beckhoff Device Manager).
Example
If you wish to set the IP address for the Ethernet interface X101/X102 to 192.168.1.67 using the DIP switches, you have to configure the DIP switches as follows:
DIP 1 DIP 2 DIP 3 DIP 4 DIP 5 DIP 6 DIP 7 DIP 8 DIP 9 DIP 10 On On Off Off Off Off On Off off off
The following value for the last byte of the IP address then results from the switched-on DIP switches: 20 + 21 + 26 = 67

EMAC1 (X001) As standard, DHCP is active and the IP address is assigned automatically. You can deactivate DHCP and assign a static IP address.
TCCCATMP1 (X101/102) As standard the first three bytes of the IP address (standard: 192.168.1) are assigned in the operating system. The last byte of the IP address (192.168.1.xxx) can be set using the DIP switches. The DIP switches are set ex factory such that DHCP is active for the Ethernet interfaces (X101, X102). The DIP switches take priority over the settings in the operating system. As a result, the settings in the operating system or via the web interface are not adopted. You have to set the DIP switches appropriately in order to set the last byte of the IP address in the operating system. Set the DIP switches 10 and 9 to "off" and 1 to 8 to "on" so that the complete IP address is adopted from the operating system.

Seconds UPS
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 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 TwinCAT 3
File path \\TwinCAT\3.1\Boot\Plc
File name
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:
· Declare important data such as counter values in the PLC as VAR PERSISTENT. Then call the function block FB_S_UPS_CX81xx cyclically in TwinCAT with the fastest task in order to control the 1second UPS (see: Function block [} 48]).
· 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: Data types [} 50]).
· You can then check the validity of the variables and monitor whether the persistent variables are loaded without error (see: PlcAppSystemInfo).

Saving and loading persistent data
The persistent data are saved in the Port_85x.bootdata file on the MicroSD card. On starting the PLC the Port_85x.bootdata file is loaded from the MicroSD card, backed up there as Port_85x.bootdata_old (backup) and then deleted.
Another current Port_85x.bootdata file is not written until the system is shut down or the 1-second UPS is activated.
If no Port_85x.bootdata file exists when starting the Embedded PC, the persistent data are invalid and will be deleted (standard setting). The reason for this is that the 1-second UPS was activated before the TwinCAT PLC was started during startup of the Embedded PC. In this case no persistent data were saved, since the system was unable to ensure sufficient buffer time for saving the data.
Always call the function block from the PLC and always use the fastest task to do so. In the case of a power failure Beckhoff recommends not calling the rest of the application in order to ensure that sufficient time remains for writing the data.
IF NOT FB_S_UPS_CX81xx.bPowerFailDetect THEN ;//Call programs and function blocks
END_IF
The rest of the application influences the CPU load and the CPU load in turn affects the period during which the persistent data are written.
Loading a backup of the 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):
[HKEY_LOCAL_MACHINE\SOFTWARE\Beckhoff\TwinCAT\Plc]"ClearInvalidPersistentData"= 0
If the backup file is to be deleted, the value of "ClearInvalidPersistentData" in the registry must be set to 1.
It is also possible in TwinCAT to specify on the left in the tree view under PLC > CX8190 whether the backup file is to be used or not.
Fig. 10: Loading a backup of the persistent data. Settings in TwinCAT 3.
The backup files will be deleted if the option Clear Invalid Persistent Data is activated. Corresponds to registry entry 1.

7.1.1 Function block
FUNCTION_BLOCK FB_S_UPS_CX81xx
The function block FB_S_UPS_CX81xx can be used on CX81xx devices with second UPS, in order to control the second UPS from the PLC. This enables the persistent data to be saved according to the selected mode in the event of a power failure. The default input values of the FB_S_UPS_CX81xx should be retained.
The second UPS does not have sufficient capacity for bridging power failures. Saving can take place only on MicroSD cards.
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).

Real Time Clock (RTC)
The real-time clock (RTC) is read out via the function blocks FB_LocalSystemTime and can be set with the function block NT_SetLocalTime (see TcUtilities.lib). The RTC is supplied by the battery and can thus continue to run in the power-off state.
CX8190

Programming
Real-time clock (RTC) running too slow
TwinCAT uses its own real-time driver. This has the advantage that the quality of the real-time has been much improved, and the jitter of the task has been reduced to a minimum. This calls the operating system from TwinCAT. The RTC on the operating system is controlled via TwinCAT and must be called at certain times.
If the task cycle time on the TwinCAT side is very long and the CPU load is high, the operating system is no longer called with sufficient frequency. As a result, the RTC on the operating system is slow. If you have noticed that the RTC is slow and the time on the CX8190 is also slow, you can apply the following troubleshooting procedure.
Remedy
The call of the RTC is always linked to a reading of the hardware RTC. This has the disadvantage of a slightly higher CPU load, but since the CPU load is already high due to your application, the additional CPU load is negligible. Adjust the settings in the registry:
[HKEY_LOCAL_MACHINE\Platform] "SoftRTC"=dword:0
Table 12: Description of the SoftRTC registry key
Value 0
1
Description
The hardware RTC is always read out when the Windows time is requested.
The hardware RTC is read out once at startup. From then on, the Windows clock continues to run via the internal system tick.
Standard setting: "SoftRTC"=dword:1

8.1
Ethernet
Ethernet was originally developed by DEC, Intel and XEROX (as the "DIX" standard) for passing data between office devices. The term nowadays generally refers to the IEEE 802.3 CSMA/CD specification, published in 1985. Because of the high acceptance around the world this technology is available everywhere and is very economical. This means that it is easy to make connections to existing networks.
There are now a number of quite different transmission media: coaxial cable (10Base5), optical fiber (10BaseF) or twisted pairs (10BaseT) with shield (STP) or without shield (UTP). Using Ethernet, different topologies can be built such as ring, line or star.
Ethernet transmits Ethernet packets from a sender to one or more receivers. This transmission takes place without acknowledgement, and without the repetition of lost packets. To achieve reliable data communication, there are protocols, such as TCP/IP, that can run on top of Ethernet.
MAC-ID
The sender and receiver of Ethernet packets are addressed by means of the MAC-ID. The MAC-ID is a 6byte identification code unique to every Ethernet device in the world. The MAC-ID consists of two parts. The first part (i.e. the first 3 bytes) is a manufacturer identifier. The identifier for Beckhoff is 00 01 05. The next 3 bytes are assigned by the manufacturer and implement a unique serial number. The MAC-ID can, for example, be used for the BootP protocol in order to set the TCP/IP number. This involves sending a telegram containing the information such as the name or the TCP/IP number to the corresponding node. You can read the MAC-ID with the KS2000 configuration software.
The Internet Protocol (IP)
The internet protocol (IP) forms the basis of this data communication. IP transports data packets from one device to another; the devices can be in the same network, or in different networks. IP here looks after the address management (finding and assigning MAC-IDs), segmentation and routing. Like the Ethernet protocol, IP does not guarantee that the data is transported - data packets can be lost, or their sequence can be changed.
TCP/IP was developed to provide standardized, reliable data exchange between any numbers of different networks. TCP/IP was developed to provide standardized, reliable data exchange between any numbers of different networks. Although the term is often used as a single concept, a number of protocols are layered together here: e.g. IP, TCP, UDP, ARP and ICMP.
Fig. 11: Structure of the Ethernet protocol.
CX8190
Version: 1.4
55
Ethernet X001 Interface Transmission Control Protocol (TCP) The Transmission Control Protocol (TCP) which runs on top of IP is a connection-oriented transport protocol. It includes error detection and handling mechanisms. Lost telegrams are repeated. User Datagram Protocol (UDP) UDP is connectionless transport protocol. It provides no control mechanism when exchanging data between sender and receiver. This results in a higher processing speed than, for example, TCP. Checking whether or not the telegram has arrived must be carried out by the higher-level protocol. Protocols running on top of TCP/IP and UDP/IP The following protocols can run on top of TCP/IP or UDP:
· ADS · ModbusTCP Both of these protocols are implemented in parallel on the Bus Coupler, so that no configuration is needed to activate the protocols.
Fig. 12: Protocols running on top of TCP/IP and UDP/IP. ADS can be used on top of either TCP or UDP, but ModbusTCP is always based on TCP/IP.

ADS-Communication
The ADS protocol (ADS: Automation Device Specification) is a transport layer within the TwinCAT system. It was developed for data exchange between the different software modules, for instance the communication between the NC and the PLC. This protocol enables communication with other tools from any point within the TwinCAT. If it is necessary to communicate with another PC or device, the ADS protocol is used on top of TCP/IP. Within a networked system it is thus possible to reach all data from any point.
Fig. 14: The ADS protocol as a transport layer within TwinCAT.
The ADS protocol runs on top of the TCP/IP or UDP/IP protocols. It allows the user within the Beckhoff system to use almost any connecting route to communicate with all the connected devices and to parameterize them. Outside the Beckhoff system a variety of methods are available to exchange data with other software tools.
Software interfaces
ADS-OCX The ADS-OCX is an Active-X component. It offers a standard interface to, for instance, Visual Basic, Delphi, etc.
ADS-DLL You can link the ADS-DLL (DLL: Dynamic Link Library) into your C program.
OPC The OPC interface is a standardized interface for communication used in automation technology. Beckhoff offer an OPC server for this purpose.
Protocol
The ADS functions provide a method for accessing the Bus Coupler information directly from the PC. ADS function blocks can be used in TwinCAT for this. The function blocks are contained in the Tc2_System.lib library. It is also equally possible to call the ADS functions from AdsOCX, ADSDLL or OPC.

Fig. 15: Structure of the ADS communication. AMSNetID The AMSNetID provides a reference to the device that is to be addressed. This is taken from the MAC address of the first Ethernet port (X001) and is printed on the side of the CX80xx. For the AMSNetID the bytes 3..6 plus ".1.1" are typically used. Example: MAC address 00-01-05-01-02-03 AMSNetID 5.1.2.3.1.1 Port number The port number distinguishes sub-elements in the connected device. Port 851: local process data PLC runtime 1 Index group The index group distinguishes different data within a port. Index offset Indicates the offset, from which reading or writing the byte is to start. Len Gives the length of the data, in bytes, that is to be read or written. TCP port number The TCP port number for the ADS protocol is 48898 or 0xBF02.

Error handling and diagnosis
State variable In TwinCAT there is a State variable under the Bus Coupler for K-bus diagnostics.
Fig. 16: 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.
