B&R X20CP1382 PLC Control Module

The B&R X20CP1382 is a compact CPU module from the X20 controller family, combining a powerful processor with integrated communication interfaces. Designed for mid-range automation tasks, this PLC control module provides real-time control, data logging, and network connectivity in a single 37.5 mm wide unit. It is ideal for machine builders and system integrators who require a scalable controller without the need for a separate bus controller.

Technical Specifications

The CPU features an Intel XScale processor running at 400 MHz. It includes 256 MB of DDR RAM and 512 MB of internal flash memory for program and data storage. The real-time clock is battery-backed. Two Ethernet ports (10/100Base-T) are available for networking, supporting open SAFETY, POWERLINK, and standard TCP/IP protocols. Additionally, the module provides a USB host port (type A) for external drives and one RS232 interface. The X2X Link master interface connects to X20 I/O modules for local I/O expansion. The module also has a slot for an additional CompactFlash card.

Power supply: 24 VDC (18-30V). Power consumption: 5 W typical. The operating temperature range is -25°C to +60°C. The module includes status LEDs for power, run, error, and communication activity. It is housed in a 37.5 mm width X20 chassis mountable on DIN rail.

Software and Programming

The X20CP1382 is programmed with B&R Automation Studio (version 4.x or later). The controller runs B&R Automation Runtime operating system, which supports multiple IEC 61131-3 languages (LD, FBD, ST, SFC, CFC) and additional high-level languages like C/C++. The integrated mapp Technology library simplifies implementing common functions (e.g., mapp View for web-based HMI). The controller supports multitasking with cycle times down to 1 ms. The built-in web server provides diagnostic access and visualization. The controller supports file-based data logging to the internal flash or external USB/CF card.

Communication Capabilities

The two Ethernet ports can be configured as a switch (daisy chaining) or as separate networks. The primary protocols include POWERLINK (for real-time motion and I/O), open SAFETY (for fail-safe communication), Modbus TCP, OPC UA, and MQTT. The USB port supports mass storage devices and can also be used for debugging. The RS232 port supports Modbus RTU or ASCII protocols. The X2X Link master allows connection of up to 64 X20 I/O modules (digital, analog, temperature, motion) over a distance of up to 100 meters.

Applications

The X20CP1382 is suitable for machine control applications such as packaging machinery, textile machines, printing presses, and special-purpose automation. It can handle coordinated motion control (up to 4 axes via POWERLINK) and advanced logic with data logging. The compact size makes it ideal for small control cabinets. The open Linux-based runtime allows integration of custom application code and third-party libraries.

Memory and Storage

The 256 MB RAM is shared between program execution and data. The 512 MB internal flash holds the runtime, application, and configuration. A CompactFlash slot (CF type I/II) provides removable storage for recipe data, logs, or additional software components. The battery-backed real-time clock maintains time during power loss (battery type CR2032, lifetime approx. 5 years).

Installation and Expansion

The X20CP1382 mounts on standard 35mm DIN rail (EN 60715) within an X20 base plate. It requires a 24V DC supply via the X20 bus (connected to the leftmost module). I/O modules are attached to the right via X2X Link; no separate bus controller is needed. The module supports hot-swapping of I/O modules (if the system is configured accordingly). Up to 64 X20 modules can be connected, with total cable length of 100 meters using standard X20 cables.

Environmental and Certifications

Ambient temperature: -25°C to +60°C (horizontal mounting). Storage: -40°C to +85°C. Relative humidity: 5-95% non-condensing. Vibration resistance: 5g (10-55 Hz). The module is IP20 rated (for use in protected cabinets). Certifications include CE, UKCA, UL 61010-2-201, cUL, DNV (marine), ATEX Zone 2 (II 3G Ex nA IIC T5 Gc), and KC (Korea).

Conclusion

The B&R X20CP1382 PLC control module delivers a compact yet powerful processing platform for mid-range automation tasks. Its integrated Ethernet, USB, and X2X Link interfaces, combined with B&R Automation Studio and mapp Technology, provide a complete solution for machine builders seeking a scalable, real-time controller.
