Product Description:

The 4PP120.0571-21 operator terminal belongs to the 4PP Power Panels series from B&R Automation. It combines an embedded controller and display so the machine can run visualization, motion supervision, and light control tasks without a separate PLC rack. By hosting application software locally and providing standard communication links, the unit reduces component count and shortens panel wiring in distributed industrial automation cells. This layout is useful where control and operator interaction need to remain in one compact panel-mounted device.

The processor runs at 266 MHz and communicates with external devices through an RS232 port for point-to-point links to drives or barcode readers. Program code and operating system images are stored in flash memory, while user data runs in 64 MB of SDRAM installed on a SO-DIMM 144-pin socket. The unit has one CompactFlash slot that accepts Type I media for recipe transfer or software updates without opening the housing. An on-chip L1 cache of 16 KB reduces memory latency, and the floating-point unit supports trigonometric and PID calculations. Two USB host ports also allow connection of a service keyboard or external storage, and a separate recovery area in flash helps preserve startup data.

The housing has a depth of 55.5 mm, while the bezel width is 212 mm and the height is 156 mm, which helps the panel fit shallow enclosures. Its passive-matrix display renders process graphics at 320 × 240 pixels, and the Geode SC2200 graphics controller shares video memory with system RAM to keep the hardware layout compact. Twin USB ports, an internal watchdog, and a battery-backed real-time clock support stable operation during routine machine use. These features allow the terminal to handle operator interface duties while retaining local control resources in the same unit.
