Product Description:

The 5PC800.B945-04 from B&R Automation belongs to the 5PC Industrial Automation Units series and functions as a compact industrial PC that hosts control logic, visualization tasks, and network communication inside a machine cabinet. It replaces separate PLC, HMI, and gateway hardware in production lines. It is intended for cabinet installation where ambient conditions favor fanless embedded computers. This arrangement allows one enclosure-mounted unit to support machine operation while remaining close to drives, I/O, and other control hardware.

Its processor is an Intel Core2 Duo T7400 built on a 65 nm manufacturing process. The dual cores operate at 2160 MHz, enabling parallel execution of control threads, while the 667 MHz front-side bus aligns processor and chipset signaling. A 32 kB L1 cache handles immediate instruction fetches, and a 4 MB shared L2 cache buffers larger data blocks to reduce memory latency during deterministic cycles. System memory is provided through two SO-DIMM sockets that accept DDR2 modules, and the configuration can reach 3 GB for larger PLC or HMI applications without paging. The architecture also supports symmetric multiprocessing so both cores can share access to the memory controller during simultaneous control and visualization tasks.

The module attaches to the Intel 945GME / Intel 82801 GHM (ICH7M-DH) chipset, which coordinates peripheral traffic and exposes graphics and storage lanes. Integrated display logic relies on Intel GMA 950 with up to 224 MB of shared video memory, and two SDVO channels can drive 1920 × 1080 DVI outputs for local operator panels. Network coupling is handled by a Realtek RTL8111B Gigabit Ethernet controller for deterministic fieldbus tunneling over standard cabling. Mass storage devices connect through 2 SATA ports for solid-state drives and an IDE channel for legacy media. The IDE channel also allows older storage media to remain in use where existing machine images depend on legacy interfaces.
