Product Description:

The 3CP380.60-1 is a central processing unit developed by B&R Automation for the System 2005 Controllers series. As the main controller, it executes logic, coordinates motion, and manages communication tasks in automated cells and process skids. Its role is to run time-critical control software, interface with distributed I/O, and pass plant data to higher-level networks, providing the deterministic operation required for modern industrial automation systems. Because it mounts inside a protected cabinet, the module relies on external wiring backplanes from the series to reach field devices.

At the heart of the unit is a Pentium III 500 processor supported by a 2x 16 kB L1 cache and a 256 kB L2 cache, a combination that shortens access latency to real-time data structures. Each Boolean instruction is completed within 0.012 µs, enabling fast interrupt handling and fine granularity in sequencing routines. The module carries 64 MB DRAM for program code and dynamic buffers, while an independent area preserves remanent variables so setpoints survive power cycles. The operating system can schedule multiple tasks because the pipeline and cache hierarchy minimize wait states during memory fetches.

Field integration is achieved through a CompactFlash slot for removable application storage and an If7xx slot that accepts fieldbus modules. Network traffic is routed through a shielded RJ45 Ethernet port, and devices connect through a 9-pin male D-sub connector running at 115.2 kbit/s on the RS232 channel; USB 1.1 is also provided for service. The controller can trigger cyclic tasks down to 200 µs, a rate that works with motion loops yet leaves headroom within the module’s 16.0 W power envelope. The controller provides 496 kB SRAM for user variables that must update at runtime, and it carries an IP20 protection rating for installation in ventilated control enclosures rather than on open machinery.
