B&R X20CP1382 Compact-S CPU Controller Module

Product Overview

The X20CP1382 (X20CP1382) is a high-performance, all-in-one controller within the B&R X20 Compact-S family. Powered by an Intel x86 400 MHz compatible processor and an integrated I/O processor, this CPU is engineered for deterministic control in complex machinery and distributed automation systems. It features a rich set of onboard interfaces, including Ethernet, POWERLINK (with poll-response chaining), and CAN bus, alongside 30 digital and 2 analog inputs/outputs integrated directly into the device. Designed for maintenance-free operation, the X20CP1382 is fanless, requires no battery, and utilizes 2 GB of onboard flash memory, making it the ideal choice for compact control cabinets where reliability and space-efficiency are paramount.

Processing Power and Memory Architecture

The X20CP1382 leverages a sophisticated memory and processing hierarchy to ensure real-time performance and data longevity.

• Dual-Processor Logic: The primary 400 MHz CPU handles complex logic and communication, while the Integrated I/O Processor manages data points in the background, minimizing jitter and maximizing throughput.

• Storage Reliability: Equipped with 2 GB eMMC flash with ECC, offering a guaranteed 40 TB of writable data—equivalent to 21.9 GB per day over 5 years.

• Non-Volatile Data: Features 32 kB of FRAM for remanent variables, ensuring critical process data is retained for over 10 years without a battery.

• Instruction Efficiency: A typical instruction cycle time of 0.0199 µs and a shortest task class cycle of 1 ms enable high-speed synchronization for packaging and motion applications.

Technical FAQs

How does the "Poll-Response Chaining" on the POWERLINK interface improve performance?

Poll-Response Chaining (PRC) optimizes network bandwidth by allowing multiple nodes to respond to a single request frame. In the X20CP1382, this enables much shorter cycle times for large-scale motion control networks compared to standard polling methods.

What are the specific requirements for the digital signal lines?

To maintain signal integrity for high-speed digital I/O, shielded lines must be used. The maximum permissible line length is 20 m to prevent EMI-induced timing errors or signal degradation.

Can the integrated real-time clock (RTC) survive a long power outage without a battery?

Yes. The X20CP1382 uses a battery-free backup system that retains the time for at least 300 hours (typically up to 1000 hours at 25 deg C). This ensures the system maintains synchronization during routine maintenance or short-term facility shutdowns.

Field Engineering & Installation Guide

• Expansion Slot Usage: The module includes one interface expansion slot. This can be used to add secondary CAN, RS485, or additional Ethernet ports. Ensure the interface module is firmly seated and the slot cover is replaced if unused to maintain IP20 ratings.

• Thermal Management: Although the module is fanless, it generates approximately 5.5 W of heat (up to 8.6 W with I/O and X2X loads). In tight enclosures, ensure vertical airflow is not obstructed. Operating temperature and eMMC data retention are sensitive to heat; maintain ambient temperatures within the specified -25 to 60 deg C range.

• Power Supply Protection: The CPU requires a 24 VDC supply. While it features integrated reverse polarity protection and a non-replaceable fuse, an external 10 A slow-blow fuse is mandatory to protect the I/O power segment and the controller from major electrical faults.

Engineering Advantages

The X20CP1382 stands out for its reACTION-capable I/O processor (processing in the background) and Visual Components support, making it a versatile choice for HMI-heavy applications. Its DNV and UL certifications ensure it is ready for maritime and hazardous industrial locations. The inclusion of the X20 end cover plate and terminal blocks in the standard delivery reduces procurement complexity, providing a complete "out-of-the-box" controller solution for high-end machine automation.
