B&R X20CP1382 Compact Programmable Logic Controller

The X20CP1382 belongs to B&R's X20 series of controllers, combining a powerful x86 processor with integrated I/O and real-time networking. It runs B&R's Automation Runtime operating system, supporting multitasking and deterministic cycle times as low as 400 µs. The unit features 512 MB of RAM and 2 GB of internal flash memory for user programs and data logs.

Technical Specifications

• CPU: Intel Atom E3827, 1.75 GHz dual-core

• Memory: 512 MB DDR3L (application), 2 GB eMMC (retain data)

• Interfaces: 2x Ethernet 10/100/1000 (switchable), 2x USB 2.0, 1x RS232/RS485

• Fieldbus: Integrated POWERLINK V2 (managed switch) and CAN bus

• I/O Configuration: Up to 64 X20 I/O modules locally via X2X Link bus

Real-Time Capabilities

The CPU handles up to 8 control tasks with independent cycle times. The integrated POWERLINK interface supports up to 240 nodes with 100 µs cycle time for motion control. The controller can synchronize drives, I/O, and vision systems on a single network. An optional license enables softPLC and softMotion functionality, turning the X20CP1382 into a complete CNC kernel.

Programming and Engineering

Using B&R's Automation Studio (version 4.12 or higher), engineers can program in IEC 61131-3 languages (LD, FBD, ST, SFC, CFC) plus C/C++ for advanced functions. The controller includes a built-in web server for remote diagnostics and HMI visualization. The onboard eMMC provides 2 GB of non-volatile storage for data logging, recipe management, and firmware updates.

Environmental and Reliability

Operating temperature: -25°C to +60°C, fanless design. IP20 protection rating, suitable for control cabinets. Humidity tolerance: 5–95% non-condensing. Vibration resistance: 4 g (10–150 Hz) per IEC 60068-2-6. The controller is fully RoHS and REACH compliant, with cULus and CE certification.

Integration Options

The X20CP1382 can act as an OPC UA server, MQTT publisher, or Modbus TCP master/slave, enabling Industry 4.0 connectivity. It supports SDL (Secure Dynamic Loading) for runtime updates without interruption. Typical applications include packaging machines, printing presses, and AGV control systems. Redundancy at the network level is possible via ring topology (RSTP) with sub-50 ms recovery.
