The Siemens 6AV6647-0AJ11-3AX1 is a SIMATIC KP400 Basic Color PN operator panel with a 4.3-inch TFT display showing 256 colors at 480 x 272 pixels, operated entirely through 8 function keys and a numeric/alphanumeric keypad rather than touch. It connects over a single PROFINET/industrial Ethernet interface, runs on 24 V DC, and configures from WinCC Basic V11 SP2 or later in the TIA Portal.
The 8 function keys and full numeric/alphanumeric keypad make this a key-operated Basic Panel: choose it over a touch variant in the KP400 family when gloved operation or a washdown environment makes reliable touch input impractical. A single PROFINET interface with Modbus TCP/IP support covers integration with both Siemens PLCs and third-party controllers on the same network without a second communication module. The 1 Mbyte user memory and 5-recipe capacity fit machine-level HMI tasks; a project needing more recipe records or a longer alarm history calls for a Comfort Panel instead.
Fits operator stations on packaging, conveying, and machine-tool cells where PROFINET links the panel to the PLC and the IP65 front withstands washdown or dust while function keys stay usable with gloves.
