In combination with the TwinCAT automation software, the CX20x0 Embedded PC becomes a powerful IEC
61131-3 PLC with up to four user tasks. In conjunction with EtherCAT and TwinCAT, it is possible to
implement very fast control processes in the microsecond range (XFC eXtreme Fast Control Technology).
It is also possible to execute Motion Control tasks with potentially up to 256 axes. Depending on the required
sampling time, several servo axes can be controlled. Even special functions such as flying saw, electronic
gearbox and cam plate can be realized.
In addition to handling real-time control tasks the TwinCAT real-time kernel leaves enough time for the user
interface (HMI). The high performance of the graphics core integrated in the CPU enables demanding

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:

5.2 Ethernet RJ45 (X000, X001)
The two Ethernet interfaces are independent; no switch is integrated. The independent Ethernet interfaces
can be configured in different ways. In delivery state the Ethernet interfaces (X000, X001) are configured for
EtherCAT communication.
Note that an additional switch is required for a line topology.
Fig.8: Ethernet interface X000, X001.
Both Ethernet interfaces reach speeds of 10 / 100 / 1000 Mbit. The LEDs on the left of the interfaces indicate
the connection status. The upper LED (LINK/ACT) indicates whether the interface is connected to a network.
If this is the case the LED is green. The LED flashes when data transfer is in progress.
The lower LED (SPEED) indicates the connection speed. The LED does not light up if the speed is 10 Mbit.
The LED is green if the speed is 100 Mbit. The LED lights up red if the speed is 1000 Mbit (gigabit).
