CX2020 | Basic CPU module BECKHOFF
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, Windows Embedded Standard 7 P or Windows 10 IoT Enterprise 2016 LTSB. TwinCAT automation software transforms a CX2020 system into a powerful PLC and motion control system that can be operated with or without visualisation. 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.
