General Information

Core Description

The 6AV6647-0AH11-3AX0 is a Siemens SIMATIC HMI Basic Panel featuring a 3.6-inch monochrome FSTN LCD display and tactile key operation. Fully compatible with PROFINET networks, this compact unit works seamlessly with S7-1200 and S7-1500 PLCs to deliver cost-effective visualization and stable industrial machine control.

System Compatibility and Alternative Models

• System Compatibility: Engineered for industrial Ethernet architectures supporting PROFINET, TCP/IP, MODBUS TCP/IP, and EtherNet/IP protocols. It provides native process coupling with Siemens S7-1200, S7-1500, S7-200, S7-300/400, LOGO!, and WinAC controllers, as well as third-party PLCs from Allen Bradley and Mitsubishi. Configured exclusively via STEP 7 / WinCC Basic or higher versions inside the TIA Portal framework.
• Alternative Model: Siemens 6AV2123-2GA03-0AX0 (SIMATIC HMI KTP400 Basic Color).
• Key Differences:

• Display Technology: The KP300 6AV6647-0AH11-3AX0 utilizes a 3.6" monochrome black/white display with a 240 x 80 resolution, while the KTP400 upgrades to a 4.3" widescreen TFT display rendering 65,536 colors at 480 x 272 resolution.
• Operator Control Type: The KP300 features pure keypad operation via 10 tactile function keys and system keys, whereas the KTP400 incorporates a combined analog resistive touchscreen alongside four configurable function keys.

Installation & Troubleshooting FAQ

Q1: What are the physical dimensional requirements for cutting out an enclosure door panel?
A: To mount the KP300 panel securely in a landscape format, the installation enclosure cutout must be precisely machined to a width of 149 mm and a height of 82 mm. The minimum required installation clear depth inside the cabinet door is 30 mm.

Q2: Why does the panel display fail to communicate with an S7-1200 controller over PROFINET?
A: First, verify that your configuration in WinCC Basic or Professional matches the physical IP addresses and subnet masks. Ensure that your PROFINET cable is seated tightly in the single RJ45 port and that the two integrated Ethernet status LEDs are illuminated or blinking to indicate active transport.

Q3: What critical threshold considerations apply when mounting the panel in environments subject to high temperatures?
A: The standard vertical landscape mounting arrangement permits a maximum operating temperature of 50 °C. However, if your mounting layout features a tilted angle inclination up to the maximum allowed limit of 35°, the ambient ceiling boundary drops down to a maximum of 40 °C.
