Product Description:
The 7CP476-010.9 central processing module is produced by B&R Automation for the System 2003 Controllers series. Designed for rack slot positions 1 and 2, the double-width unit acts as the control point that links field signals, local memory, and network buses inside an automated cell. It receives backplane power, executes IEC-61131 logic, and exchanges data with distributed nodes so that drives, valves, and sensors remain synchronized during packaging, material handling, or assembly operations.
The controller operates from a regulated 24 VDC supply, and its internal electronics draw 12.15 W under nominal load. Each logic scan is completed in 0.5 µs, allowing high-speed positioning or counting tasks without oversampling problems during fast machine cycles. One electrically isolated CAN channel provides one CAN interface for network-capable peer traffic or remote I/O expansion, while serial diagnostics can be hosted through the built-in one RS-232 interface. Four screw-in module slots accept additional signal adapters, and a single PCMCIA bay supports removable program storage or software loading without an external computer. These features keep communication and service functions inside one hardware node, which helps reduce panel wiring and the number of separate modules.
For process connectivity, the CPU can address up to 272 digital I/O points and 80 analog I/O channels through stackable terminal cards. A nonvolatile 512 kB system FlashPROM stores system data, while application code and recipes occupy a separate 1.5 MB user FlashPROM; 750 kB of battery-backed SRAM buffers variables during power cycles. Separate nonvolatile and battery-backed memory areas allow system functions, user logic, and changing process values to be retained in different sections. Because the controller retains program data during supply interruptions and supports online expansion, signal counts can be scaled or software can be updated in the field without changing the base CPU.
