B&R X20CP3585 X20 System Intel Atom 1.0 GHz CPU

Product Overview

The X20CP3585 (X20CP3585) is a high-performance central processing unit within the B&R X20 system, featuring an Intel Atom 1.0 GHz processor for demanding automation architectures. Equipped with 256 MB DDR2 RAM and 1 MB of remanent SRAM, this controller is designed to handle complex control algorithms, high-speed data processing, and multi-axis motion control with ease. In large-scale industrial operations such as oil refineries, power generation plants, and advanced semiconductor manufacturing, the X20CP3585 acts as the powerful core of the control system, providing the necessary computational bandwidth to manage thousands of I/O points. Its fanless design and CompactFlash-based removable application memory ensure high reliability and easy maintenance, significantly reducing the mean time to repair (MTTR) and eliminating the risks associated with mechanical cooling failure.

Technical Configuration

The hardware configuration of the X20CP3585 is optimized for maximum modularity and communication versatility. It features three internal insert slots for X20 interface modules, allowing for the addition of fieldbus protocols like CANopen, DeviceNet, or Profibus without increasing the footprint. The onboard communication suite is comprehensive, including a real-time POWERLINK (V1/V2) interface, a standard Ethernet port, dual USB 2.0 ports, and an RS232 serial interface. The integrated X2X Link power supply manages the local backplane, while the system status is monitored through a series of dedicated indicators for CPU function, overtemperature, and battery health. With a typical power consumption of 8.8 W (excluding USB and interface modules), the CPU delivers a high performance-to-power ratio, maintaining stability in a compact 8.5 cm x 20 cm x 9.9 cm chassis.

Technical Specifications

Technical FAQs

Can the X20CP3585 handle real-time motion control for synchronized axes?

Yes, utilizing the integrated POWERLINK interface and its 1.0 GHz Atom processor, the X20CP3585 is capable of managing complex synchronized motion tasks with sub-millisecond cycle times, making it ideal for CNC and robotic applications.

What happens to the program data if the battery fails?

The module contains 1 MB of SRAM for remanent variables. While the battery maintains this data during power-off states, the application program itself is stored on the removable CompactFlash card, ensuring that the machine logic is never lost due to a battery failure.

Is the CompactFlash card included with the CPU module?

The CompactFlash card is an "Application Memory" component and is typically ordered separately based on the storage requirements of your specific Automation Studio project. Ensure you use industrial-grade B&R cards for guaranteed compatibility.

Engineering & Installation Guide

• CompactFlash Handling: Always ensure the power to the CPU is completely disconnected before inserting or removing the CompactFlash card. Failure to do so can result in file system corruption or hardware damage to the memory interface.

• Battery Maintenance: The CPU monitors battery voltage levels via a dedicated status indicator. When the battery LED signals a low-voltage state, replace the battery within the next scheduled maintenance window while the system is powered on to prevent the loss of remanent SRAM data.

• Interface Module Installation: When utilizing the three insert slots, ensure the interface modules are fully seated and the locking mechanism is engaged. Improperly seated modules can cause intermittent X2X Link errors or bus timeouts that are difficult to diagnose during full-speed operation.
