4 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

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.
