Beckhoff CX1020-0012 Embedded PLC Module
The Beckhoff CX1020-0012 is a compact embedded PLC module that combines the functionality of an industrial PC with the real-time capabilities of a programmable logic controller. It is designed for control applications requiring high computing performance, extensive communication options, and a small footprint. The module runs TwinCAT software, providing a unified programming environment for logic, motion, and vision.
Processor and Memory
Equipped with an Intel Celeron M processor at 1 GHz, the CX1020-0012 includes 512 MB of DDR RAM and 1 GB of internal flash memory for the operating system and application storage. An additional microSD slot allows for memory expansion up to 16 GB for data logging.
Real-Time Features
The module supports Beckhoff's real-time kernel, achieving cycle times down to 50 µs for I/O processing and 1 ms for motion control. It includes a distributed clock function for precise synchronization of EtherCAT devices.
Communication Interfaces
Onboard ports include: one 10/100 Ethernet (for programming and standard TCP/IP), one EtherCAT port (master) for high-speed I/O and servo drives, one USB 2.0, and one RS-232 serial port. Optional fieldbus modules (Profibus, CANopen) can be added via the system bus.
Programming and Runtime
The CX1020-0012 is programmed using TwinCAT 3, supporting all IEC 61131-3 languages, as well as C++ and MATLAB/Simulink. The runtime includes a built-in web server for remote monitoring and OPC UA for secure data exchange.
