B&R 7CP474.60-1 B&R 2003 CPU Processor Module

Product Overview

The 7CP474.60-1 (7CP474.60-1) is a high-performance CPU processor module designed for the B&R 2003 series control architecture. Engineered for demanding industrial environments such as automated manufacturing lines, packaging machinery, and process control systems, this module acts as the central intelligence of the controller. By integrating robust computing power with reliable memory management, the 7CP474.60-1 ensures precise execution of control tasks and minimizes unscheduled downtime. Its compact, double-width design allows for seamless integration into existing rack systems, providing a scalable solution for complex automation requirements where operational stability is critical.

Technical Configuration

The 7CP474.60-1 utilizes a sophisticated hardware architecture tailored for real-time processing and efficient data handling. It is equipped with 100 KByte of SRAM for user-defined programs and data, complemented by 512 KByte of FlashPROM for both system and user firmware storage. This non-volatile memory structure ensures that critical configuration data is retained even during power cycles.

The module features a dedicated I/O bus interface via a 9-pin D-type socket, facilitating reliable communication with peripherals. The real-time clock is also non-volatile with a 1-second resolution, enabling precise time-stamping of process events. Status monitoring is simplified through integrated LEDs, which provide immediate visual feedback on the module's operating state. Designed for 24 VDC input, the module maintains a maximum power consumption of 20 W, optimizing energy efficiency within the control cabinet.

Technical Specifications

FAQs

Is the 7CP474.60-1 compatible with older B&R 2003 series racks?

Yes, this module is designed to be fully compatible with the B&R 2003 series backplane architecture, provided the system has the required double-width slot availability.

What should I do if the status LEDs indicate an error?

First, verify that the 24 VDC input supply is stable and within nominal operating range. Check the 9-pin D-type interface for secure connection. If the error persists, perform a power cycle; if the fault continues, the module may require professional diagnostic testing or replacement.

Does this module require a battery for memory retention?

The 7CP474.60-1 uses non-volatile FlashPROM for critical storage, which does not require a battery to retain data. The real-time clock is also designed as a non-volatile component.

Can this unit be used as a direct replacement for discontinued B&R processors?

It is a standard component for the 2003 series. Please verify your existing firmware version compatibility before installation, as specific system updates may be necessary depending on your application requirements.

Installation Guidelines and Best Practices

• Thermal Management: The 7CP474.60-1 generates heat during operation. Ensure sufficient clearance (at least 50 mm) above and below the module within the cabinet to facilitate natural convection cooling. Avoid installing the module directly above high-heat generating components like power converters.
• Shielding and Grounding: Always use shielded twisted-pair cables for the 9-pin D-type communication interface. The cable shield must be grounded at one point only to prevent ground loops, which can induce electromagnetic interference (EMI) and cause communication instability.
• Safety Precautions: Ensure that the 24 VDC power source is isolated and properly fused before installation. Always discharge static electricity by touching a grounded metal surface before handling the module to prevent damage to internal CMOS components. Do not hot-swap the module unless specifically indicated by the system manual; it is recommended to power down the rack before inserting or removing the CPU.
