B&R 7CP476.60-1 – System 2003 Central Processor with 272 DI / 80 AI Expansion

Product Overview

The B&R 7CP476.60-1 is a central processor interface module designed for the B&R System 2003 modular automation platform, serving as the primary computational and control engine for legacy industrial machinery installations. As the core CPU within a System 2003 rack configuration, the B&R 7CP476.60-1 executes user control programs, coordinates local and remote I/O data exchange, and manages communication across the backplane system bus. This module occupies the primary processor slot (slots 1+2 as a double-width module) and provides the deterministic processing capability required for machine control, packaging lines, and material handling applications commissioned during the late 1990s through the 2000s.

The B&R 7CP476.60-1 integrates 750 KB of battery-buffered SRAM for runtime data, recipes, and retentive variables, alongside 1.5 MB of FlashPROM for permanent program and configuration storage. This memory architecture ensures that the control program survives power cycles without battery dependency, while dynamic runtime data is protected by a removable 3V lithium backup cell. Onboard communication resources include one RS232 serial interface for programming and diagnostic access via B&R Automation Studio, and one electrically isolated CAN bus interface for robust networking with remote I/O stations, drives, and intelligent field devices. The B&R 7CP476.60-1 also provides four screw-in slots for optional interface and expansion modules, enabling protocol expansion and specialized function integration as application requirements dictate.
