Product Description:

The 4PP420.0571-K48 operator terminal is produced by B & R Automation for the 4PP Power Panels series. As an integrated human-machine interface, it combines a color display, a Geode LX800 processor, and touch sensing into a panel that mounts directly on equipment. In an automation cell, it manages on-screen diagnostics, recipe handling, and simple motion commands while exchanging data with controllers over Ethernet, serial, or fieldbus adapters.

Its Geode LX800 runs at 500 MHz, giving sufficient headroom for visualization tasks and control logic executed locally. The screen size of 5.7" (144 mm) pairs with a 320 × 240-pixel resolution so status graphics remain legible at arm’s length. Volatile program data reside in 128 MB of SDRAM, and 512 kB of SRAM retains startup variables. A CompactFlash Type I slot permits removable storage, while two USB host ports support service uploads. The panel draws control power from a single 24 VDC source, and the overall demand stays within 12 W, which simplifies cabinet heat calculations. An analog resistive touch layer allows operation with gloved hands, and a dedicated RS232 port links legacy drives or sensors.

Network communication is handled by the Intel 82551ER controller that delivers deterministic messaging at up to 100 Mbit/s; this speed suits distributed I/O or real-time data exchange with higher-level SCADA nodes. Application code, fonts, and bitmaps are stored in 2 MB of flash for local runtime resources. The aluminum front satisfies IP65 ingress protection, allowing washdown from the machine face while internal electronics remain ventilated within the cabinet. Ethernet networking and local touch input let the terminal present status information and accept commands from the same panel.
