Product Description:

B & R Automation manufactures the 7CP470.60-2, a central processing unit for the System 2003 Controllers series. The module serves as the control core inside modular PLC racks, coordinating discrete and analog field signals, scheduling tasks, and executing user programs for packaging lines, material-handling stations, and other industrial cells that rely on deterministic cycle timing. It is intended for centralized machine control where dependable scan execution and organized I/O handling are required across multiple connected modules.

The controller is supplied from a regulated 24 VDC source and draws a maximum of 20.0 W, so cabinet power budgeting remains manageable. Each Boolean instruction is processed in 1.6 µs, which supports short reaction times during cyclic control. Real-time variables are buffered in 350 KB SRAM, allowing counters, flags, and position-related values to remain available between scans. Up to 4 analog signal boards can be plugged into the local backplane, so the CPU can work directly with temperature, pressure, or similar process inputs without separate conversion hardware. A hardware watchdog supervises code execution and forces a safe shutdown if the program stalls, while the 9-pin D-Sub bus connector links the unit to the proprietary I/O backbone. Application data is stored in onboard nonvolatile memory, so removable storage is not required for normal operation.

For expansion, the rack accepts 8 logic slice positions, providing space for digital relays, counters, or motion-related modules. The integrated CAN interface exchanges process data at up to 500 kBit/s, and the service RS-232 port reaches 57.6 kBit/s for setup software or barcode scanners. Protection is rated at IP20, so the unit is intended for installation inside closed electrical enclosures. A one-second real-time clock resolution supports basic time stamping, and the dual 512 KB user PROM mirrors application code to help protect stored data during power loss.
