Equipped with a powerful 1 GHz ARM Cortex A8 processor and large capacity microSD card, Beckhoff’s fanless CX9020 DIN-rail mountable controller is suitable for a wide range of PLC and motion control applications in small- and medium-sized machines, systems or buildings. A multi-interface can be configured ex factory, if required, offering scope for numerous optional extensions, from an audio interface up to the connection of fieldbus masters or slaves. The controller automatically detects the connected bus terminals (K-bus) or EtherCAT terminals (E-bus) and switches to the respective mode for more convenient system management. It has an access to 1 GB of internal DDR3 RAM and comes with a 256MB microSD card for the Microsoft Embedded Compact 7 operating system. A free microSD card slot can be used for additional data storage. In addition, 128KB NOVRAM is available for data storage in the event of a power failure. The basic version is available with two 10/100 Mbit/s Ethernet ports (internal switch), four USB 2.0 connections and a DVI-D interface. The multi-optional interface enables integration of an additional interface such as slave only EtherCAT, PROFINET, Ether/IP, PROFIBUS, CANopen, DeviceNet, RS-232/-422/-485 serial interface or audio. Since the ARM Cortex A8 has a hardware-based floating point unit, the controller is also suitable for motion control applications. In combination with the TwinCAT automation software platform, it becomes a high-performance PLC and Motion Controller that can be used with or without visualization. The extended operating temperature range between -25 and 60 °C enables application in demanding environments.
