Beckhoff: Embedded PC (CX2020 Series)
Embedded PC series CX2000
The CX2020, CX2030 and CX2040 Embedded PCs extend the CX product family with versions with very high CPU power (optionally with multi-core) and enable direct connection of Bus Terminals or EtherCAT Terminals.
The CX2000 in conjunction with EtherCAT and TwinCAT enables very fast control processes in the microsecond range (eXtreme Fast Control Technology).
The basic CPU modules have a CFast memory card, two independent Gbit Ethernet interfaces, four USB 2.0 interfaces and a DVI-I interface as standard. In addition there are fieldbus or serial connection options. Please note that these have to be specified with the order, i.e. retrospective installation is not possible. Other components from the CX2000 family can be connected via the multi-pin terminals on either side. The multi-pin terminal on the left-hand side enables the connection of up to four further optional modules.
The individual system component are 22 mm wide or a multiple thereof. The basic unit consists of the CX20x0 CPU module and a power supply module (CX2100-0xxx).
Power supply unit with integrated I/O interface and optional UPS
The 24 V DC power supply unit is available in four different versions:
CX2100-0004: E-bus/K-bus power supply unit with automatic switchover
CX2100-0014: E-bus/K-bus power supply unit with automatic switchover and passive ventilation
CX2100-0904: E-bus/K-bus power supply unit with automatic switchover and integrated capacitive UPS
CX2100-0914: E-bus/K-bus power supply unit with automatic switchover and integrated electronic charging unit for external battery packs in order to maintain UPS functionality
All power supply units feature an illuminated anti-glare LC display with two rows of 16 characters each for displaying status messages.
The application programs can also use the display for displaying application-specific texts.
EtherCAT as a fast I/O system
The CX2020, CX2030 and CX2040 Embedded PCs were developed with a view towards optimized interaction with EtherCAT. EtherCAT offers a wide range of application options. The separate Gbit Ethernet interfaces enable EtherCAT to be used with cable redundancy by using one of the Ethernet interfaces as redundancy port. In addition, devices with EtherCAT slave interface can be operated such that several intelligent controllers can be synchronized via an EtherCAT network.
PLC, Motion Control, interpolation and visualization
As IPC on a DIN rail the CX2000 in conjunction with TwinCAT offers the functionality of large Industrial PCs. Multi-core CPUs in conjunction with TwinCAT 3 enable PLC projects to be distributed to several cores, resulting in significant performance gains.
Moreover, all TwinCAT functionalities are available for Motion Control applications: in theory, up to 256 axes can be controlled. In addition to simple point-to-point movements, more complex multi-axis functions (electronic gearbox, cam plates, flying saw etc.) can be implemented. Due to the high-performance CPUs in the CX2000, interpolating 3-D path movements can also be implemented and DIN 66025 programs executed.
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 kernel integrated in the CPU enables demanding visualizations with advanced user interfaces to be released.
CX2020 | Basic CPU module
The CX2020 has a 1.4 GHz Intel® Celeron® CPU, it is fanless and has no rotating components. In addition to the CPU and chipset, the CX2020 also contains the main memory with 2 GB RAM as standard. 4 GB is possible as option. The controller boots from the CFast flash memory card.
The basic configuration of the CX2020 includes a CFast memory card, two independent Gbit Ethernet interfaces, four USB 2.0 interfaces and a DVI-I interface.
The CPU has a 128 kB NOVRAM persistent data memory for situations where no UPS is used.
The unit can optionally be ordered with a fieldbus or serial interface. Other components from the CX2000 family can be connected via the multi-pin terminals on either side. The operating system is Microsoft Windows Embedded Compact 7 or Windows Embedded Standard 7 P. TwinCAT automation software transforms a CX2020 system into a powerful PLC and Motion Control system that can be operated with or without visualization. Due to its high-performance the CX2020 can be used for interpolating 3-D path movements with TwinCAT NC I.
Up to four modules can be connected to the basic CPU module. The connection order is irrelevant. Internally the modules are connected via PCI Express and can be connected subsequently to the CPU "in the field".
The power supply for the CPU module comes from a CX2100 power supply module, which is connected on the right-hand side of the CPU. Two further CFast memory card modules (CX2550-0010) can be connected between the power supply unit and the CPU, so that a total of up to three CFast cards can be used. RAID can be used in situations where more than one CFast card is used.
The extended operating temperature range between -25 and +60 °C enables application in climatically demanding situations.
