Product Description:
The 4PP251.0571-A5 is an operator interface panel produced by B&R Automation and belongs to the 4PP Power Panels series. It combines control processing and visualization in a single front-mounted module, allowing machinery to be managed directly at the installation point without a separate PLC rack. Its integrated format supports local operation where space is limited and direct access to machine functions is important.
The panel runs on a Geode SC2200 processor clocked at 266 MHz, allowing deterministic execution of automation code and display tasks. Program data reside in 64 MB SDRAM, while a 256 kByte SRAM segment stores retentive variables that must survive power cycles. Two APCI expansion slots let the user add fieldbus or specialty I/O cards, and one Type I CompactFlash slot provides removable program storage. Communication to higher-level networks is handled through a 10/100 Mbit/s RJ45 Ethernet port, and short-term data logging or recipe downloads can also move through that link. Nonvolatile resources include 2 MByte of flash for system software and 4 MByte of shared graphics memory for the onboard controller frame buffer. The unit is powered by a single 24 VDC ±25% source, and the aluminum front has an IP65 rating to resist dust and washdown exposure at the machine face.
Operator feedback is delivered on a 5.7 in color LCD that reaches 150 cd/m² brightness for readability under factory lighting. The touch screen displays images at 320 x 240 pixels, which matches many legacy HMI graphics while keeping refresh demands modest for the embedded graphics subsystem. The unit has 2 x USB 1.1 ports on the front for service keyboards, barcode readers, or memory sticks used for file transfer. These interface and display resources support local access to motion commands, parameter dialogs, and diagnostic pages without relying on a separate external terminal.
