The CX2000 devices are equipped with Intel® processors from the second generation of the 32-nm series (‘Sandy Bridge’). Power-saving Celeron® types are also available, making fanless options available. The Embedded PCs’ operating systems benefits from the fast, integrated graphic core as well as faster DDR3 memory. The three devices from the new CX2000 series are the following:
1. CX2020 | 2nd Generation Intel® Celeron® @1.4 GHz, single-core
2. CX2030 | 2nd Generation Intel® Core™ i7 @1.5 GHz, dual-core
3. CX2040 | 2nd Generation Intel® Core™ i7 @2.1 GHz, quad-core
As in the first generation of Embedded PCs, the new CX2000 devices consist of individual components that the user can order separately and assemble in the field, simply by plugging them together. The CX2000 housing concept combines a metallic basic housing with front panels made of a special screening plastic.
The basic CPU module from the new CX series always has one DVI port, four USB ports and two Ethernet ports. A factory-configurable internal slot known as a ‘magic interface’ can optionally perform the function of an astoundingly wide range of interfaces: fieldbus master and slave implementations are possible here, e.g. for EtherCAT (slave), PROFINET, EtherNet/IP, PROFIBUS, CANopen and DeviceNet, as well as serial interfaces (RS232/RS422/RS485).
The modularity of the CX2000 devices on the left-hand side of the CPU is based on PCI Express as the bus system and offers a bandwidth of 5 gigatransfers per second (GT/s) per PCIe TX/RX channel. This enables the connection of a wide variety of interfaces; for example, a maximum of four modules each with two independent Ethernet 1 Gbit ports can be connected. Alternately, up to eight serial interfaces can be connected, which are each implemented in pairs as RS232 or RS422/RS485. The number of possible USB interfaces can also be multiplied: four high-speed (480 MB/s) USB 2.0 interfaces can be connected per module.
The Embedded PC is a convergence of standardised PC technology with “DIN rail-friendly” features to form a flexible industrial controller. On the hardware side the devices from the CX2000 series offer I/O support and a direct connection for Beckhoff Bus Terminals and EtherCAT Terminals. Another new feature is automatic recognition of the respective I/O system in the CX2000 power supply module, which can simplify customer orders. On the software side, the new CX generation also continues to exclusively support Microsoft operating systems in the form of Windows Embedded Standard 7 or Windows 8, depending upon availability.
The new CX2000 series from Beckhoff: Embedded PCs with one to four processor cores, suitable for PLC, NC and CNC. The multi-core capability of the new CX2000 generation is naturally optimised for use with the new TwinCAT 3 software from Beckhoff. Now not only the operating system, but also the real-time controller can be distributed to different processor cores.
