7CP474.60-1 B&R CPU Module/Central Processing Unit
Product Dimensions：
Product Description (Detailed Explanation)
The 7CP474.60-1 serves as the primary controller in a System 2003 rack. It integrates a CPU, power supply, and multiple communication interfaces into a single unit. This module is specifically noted for its CP-Interface, which allows it to connect to B&R Panelware operator panels or other modular extensions.
The architecture is bit-modular, supporting up to 4 screw-in modules directly on the CPU unit to expand its I/O capabilities. It is a network-capable device, featuring an electrically isolated CAN interface and a serial RS232 port for programming or peripheral connectivity.

Product Advantages (Key Benefits)
-
Integrated Design: Combines the CPU and a 24V power supply in one module, reducing the total footprint and simplifying cabinet wiring.
-
Modular Scalability: With 4 integrated slots for screw-in modules, users can add digital/analog I/O or specialized functions without adding separate bus modules.
-
Robust Communication: The electrically isolated CAN interface ensures reliable data transmission even in electrically noisy industrial environments.
-
Longevity: Part of the proven System 2003 lineup, known for its long-term reliability in demanding machine control applications.
-
Panelware Compatibility: The dedicated CP-interface simplifies the integration of local HMI solutions for machine-level operation.
Precautions (Important Notes)
-
Discontinued Status: This module is widely considered “Legacy” or “Discontinued” by the manufacturer. Future availability typically relies on refurbished or surplus stock.
-
Battery Maintenance: The SRAM requires a backup battery to retain data during power loss. Check and replace the battery according to the maintenance schedule to avoid program loss.
-
Thermal Management: While passively cooled, ensure the module is mounted in the correct vertical orientation to allow natural air convection. Do not block the ventilation slots.
-
Configuration: Ensure the firmware and module configuration in B&R Automation Studio match the physical hardware revisions to prevent startup errors.
Product Applications (Typical Use Cases)
-
Medium-Scale Machine Control: Used as the brain for packaging machines, textile equipment, and plastic injection molding machines.
-
Distributed Automation: Serving as a local controller in a larger factory network, communicating via CAN to other I/O islands.
-
Upgrade/Maintenance: Frequently used as a replacement part for existing production lines that utilize the B&R System 2003 architecture.
-
Building Automation: Managing HVAC systems or complex pumping stations where a combination of analog and digital signals is required.
