Product Description:

The 4PP065.0571-K05 operator terminal is produced by B&R Automation within the 4PP Power Panels series. It combines an embedded controller and HMI functions in a single unit for machine-level automation. By integrating program execution and on-screen interaction, the panel simplifies wiring and reduces cabinet space in packaging lines, assembly cells, and other distributed control nodes. Operators can view process status and enter commands from the same device that manages local control tasks.

Its front face carries a 5.7 in diagonal TFT color display that renders QVGA resolution for status graphics and diagnostics. Capacitive sensing is not used because the panel relies on a resistive touchscreen layer for direct data entry. Supply voltage is 24 VDC, so it connects directly to the standard control power bus. Communication to upper-level networks is handled through one Ethernet port, while axis or I/O modules link through a dedicated X2X port. A single CompactFlash slot permits program and recipe storage or field updates without requiring a separate computer.

The local interface supplements the touch overlay with 10 function keys whose fixed legends can be mapped to frequently used commands. Runtime data is processed in 128 MB DRAM, while nonvolatile user data is kept in 232 kB SRAM. Process values that must survive power cycles are copied automatically into 32 kB of remanent memory. The DRAM region hosts the real-time kernel and the display framework, while the smaller SRAM is reserved for user structures. This separation prevents application variables from exhausting system memory and helps maintain deterministic task scheduling during cyclical scan times. Function keys are scanned independently so operator feedback is not delayed by touch actions. The panel can therefore handle logic execution, trend capture, and alarm handling without a separate external PLC.
