Product Description:
The 7CP476-010.97 CPU module is produced by B & R Automation and is part of the System 2003 Controllers series. Serving as the central controller in a machine rack, it executes user programs, supervises local I/O, and exchanges data with supervisory networks. Within an industrial automation line, the module’s role is to provide deterministic logic processing so actuators respond to sensor events at the required production cadence.
The controller operates from a 24 VDC supply and is enclosed to the IP20 protection level, requiring placement inside a control cabinet. Its pipeline finishes one instruction in 0.5 µs, and it can schedule a fastest task cycle of 1 ms for time-critical routines. A single electrically isolated CAN interface supports node communication at 500 kBit/s, while the lone RS232 port reaches 57.6 kBit/s for parameter download or diagnostics. One PCMCIA slot accepts removable cards, and four screw-in slots secure the unit to the backplane. Output devices connected through its I/O header may draw up to 12.15 W, letting local sensors or indicators be powered directly from the module.
Total heat dissipation is governed by a module demand of 20.0 W, helping panel designers size power supplies and ventilation. Firmware and boot routines reside in a 512 kB FlashPROM system area, which remains unchanged during normal operation. Application code can occupy up to 1.5 MB of dedicated user FlashPROM, and variable data is buffered in 750 kB of SRAM to preserve real-time records between scans. Because only one CAN and one RS232 channel are present, memory resources must accommodate all protocol stacks and data logging internally. This separation of system and user storage prevents accidental overwriting of critical startup code while still giving adequate space for complex control algorithms.
