Product Description:
The 7CP476.60-1 is a central processing unit assembled by B&R Automation for the System 2003 Controllers series. Within a System 2003 rack, this controller executes application code, manages local and distributed I/O, and coordinates time-critical tasks on production lines or machine cells. Its role in industrial automation is to provide deterministic program execution and communication services so motion, safety, and process modules respond within predictable time frames.
The logic section is powered from a nominal 24 VDC supply and draws a maximum of 20.0 W, while the I/O ports can deliver 12.5 W to field sensors or indicators. A hardware watchdog is present and forces a safe state if the control program does not toggle it in time. The fastest task class can be scheduled every 1 ms, whereas a typical single instruction completes in only 0.5 µs; these values support deterministic throughput for motion loops or high-speed counting. CAN bus communication reaches 500 kBit/s for distributed module updates, and the built-in RS-232 channel transfers diagnostics at up to 57.6 kBit/s. This mix of processing speed and communication capacity supports cabinet-mounted control systems that must exchange field data and diagnostic information without a separate processor.
The memory map includes 750 KB SRAM for retentive variables and a 1.5 MB FlashPROM region for user programs. An additional 512 KB FlashPROM area is reserved for the operating system, keeping system functions separate from application storage. Four analog module slots, sixteen logical module slots, and four local screw-in slots allow digital, analog, and communication modules to be combined without backplane changes. A real-time clock with 1 s resolution timestamps events, and the enclosure is rated IP20 for installation inside a control cabinet.
