7XX40850-1 B&R Central Control Unit

Product  Description：

B&R (Bernecker + Rainer) Central Control Units, primarily represented by the X20 and APC (Automation PC) series, serve as the high-performance core of the B&R automation ecosystem. These units are designed to handle complex logic, high-speed motion control, and extensive data processing within a single integrated environment. By utilizing an industrial-grade real-time operating system, B&R control units ensure deterministic performance and seamless synchronization between the CPU and peripheral hardware.

Product Parameters

The technical profile of a B&R Central Control Unit is characterized by high processing density and modular scalability:

• Processor Architecture: Ranges from ultra-compact Intel Atom and Celeron processors to high-performance Core i-series CPUs for heavy computational tasks.

• Memory Capacity: Options typically include 256MB to 16GB of DDR RAM, with non-volatile memory provided via industrial-grade CompactFlash or CFast cards for reliable program storage.

• Cycle Times: Capable of extremely low system scan times, often reaching sub-millisecond levels (e.g., 100 microseconds) for high-speed motion applications.

• Communication Ports: Built-in POWERLINK for real-time Ethernet, along with standard Gigabit Ethernet, USB 3.0, and RS232/RS485 serial interfaces.

• I/O Expandability: Supports direct backplane connection of X20 I/O modules or distributed control via fieldbus interfaces.

• Environmental Protection: Rated for operating temperatures from -25°C to 60°C, with high resistance to shock (30g) and vibration (5g).

Product Advantages

B&R Central Control Units are distinguished by their "Scalability+ " philosophy and technical robustness:

• Unified Engineering Environment: All control units are programmed using Automation Studio, allowing developers to reuse code across different hardware classes from small PLCs to industrial PCs.

• Deterministic Communication: Integrated POWERLINK technology ensures that motion control and standard I/O data are transmitted with microsecond precision and zero jitter.

• Fanless and Maintenance-Free: Many central units are designed with advanced heat dissipation technology, eliminating the need for fans or other moving parts that typically reduce hardware lifespan.

• Advanced Virtualization: Supports hypervisor technology, allowing a single control unit to run a real-time operating system alongside a standard OS like Windows or Linux simultaneously.

• Integrated Safety: Supports openSAFETY protocols, enabling the execution of safety-critical logic up to SIL 3 / PLe within the same hardware architecture.

Product Applications

These control units are widely deployed in industries requiring maximum precision and high data throughput:

• Packaging Machinery: Coordinating high-speed "flying saw" applications, multi-axis labeling, and synchronized conveyor systems.

• Plastics Industry: Controlling complex injection molding processes where high-speed pressure and temperature regulation are critical.

• Energy and Grid Control: Managing wind turbine pitch control and grid synchronization for renewable energy farms.

• Mobile Automation: Serving as the main controller for outdoor heavy machinery and specialized vehicles due to their high vibration resistance.

• Semiconductor Manufacturing: Providing the nanometer-level precision required for wafer handling and chemical vapor deposition processes.

Important Precautions

To maintain the long-term reliability of the B&R central unit, the following precautions are essential:

• Storage Medium Protection: Never remove the CompactFlash or CFast card while the system is powered on, as this can lead to file system corruption and boot failure.

• Cooling Clearances: Ensure that the control unit is mounted with the recommended spacing (typically 30mm to 50mm) above and below the unit to allow for natural heat convection.

• Power Quality: Use a regulated 24V DC power supply and ensure that the unit is properly fused. Voltage spikes beyond the specified range can damage the internal CPU voltage regulators.

• Grounding and EMI: Connect the mounting rail to a low-impedance functional ground. Use shielded cables for all communication ports to prevent electromagnetic interference from causing system resets.

• Backup and Recovery: Regularly back up the system software and retain a copy of the hardware configuration. In the event of a hardware replacement, the system can be restored quickly using the B&R "Cold Start" or SD card recovery features.
