Application Scenarios
In a large automotive manufacturing plant, operators struggled with inconsistent machine control due to the lack of tactile feedback on touchscreen HMIs in a high-vibration environment near stamping presses. After deploying the Siemens 6AV2124-1MC01-0AX0, the plant achieved precise and reliable machine control through its 34 programmable function keys with LED status indicators . The operator feedback was overwhelmingly positive, citing the confidence provided by physical keys and the real-time visual status from the key LEDs, which reduced operational errors by 25%.
The 6AV2124-1MC01-0AX0 addresses critical industrial pain points:
- Need for reliable operator input in high-vibration or harsh industrial environments
- Requirement for rapid, tactile feedback during frequent machine operations
- Integration of multiple communication protocols (PROFINET, PROFIBUS, MPI) for seamless connectivity
- Demand for high-resolution visualization with 16 million colors for detailed process monitoring

Technical Principles and Innovative Values
Innovation Point 1: Key-Based Operation with Tactile Feedback
The Siemens 6AV2124-1MC01-0AX0 features 34 programmable function keys with integrated LEDs, providing operators with clear tactile feedback and visual status indication for each key . Unlike touch-only panels, the membrane keyboard design ensures reliable operation even when wearing gloves or in environments with moisture or debris, making it the preferred choice for heavy industrial applications.
Innovation Point 2: High-Resolution Widescreen Visualization
With a 1280 x 800 pixel resolution and 16 million colors on a 12.1-inch TFT display, the 6AV2124-1MC01-0AX0 delivers exceptional image clarity and color fidelity . The LED backlight has an impressive MTBF of 80,000 hours and is dimmable from 0-100%, ensuring long-term reliability and adaptable brightness for various lighting conditions .
Innovation Point 3: Multi-Protocol Communication Flexibility
The panel supports a comprehensive range of communication protocols including PROFINET with IRT (isochronous real-time), PROFIBUS DP, MPI, EtherNet/IP, and Modbus TCP/IP . The integrated two-port PROFINET switch enables cost-effective line topologies without requiring external switches, reducing hardware costs and cabling complexity.
Innovation Point 4: Comprehensive Connectivity and Expansion
Equipped with two USB 2.0 ports, a USB Mini B port, and two SD card slots, the 6AV2124-1MC01-0AX0 offers flexible data exchange and firmware update capabilities . The RS 422/485 interface provides compatibility with legacy systems, ensuring seamless migration from older HMI platforms .
Innovation Point 5: Rugged Construction for Harsh Environments
With IP65-rated front protection, an aluminum front housing, and an operating temperature range of 0°C to 50°C, the Siemens 6AV2124-1MC01-0AX0 is built to withstand demanding industrial conditions . The panel also holds ATEX Zone 2/22 and multiple marine approvals (GL, ABS, BV, DNV), making it suitable for hazardous area and maritime applications .
Innovation Point 6: Advanced Software Integration
Configurable with WinCC Comfort (TIA Portal) from V11 onwards, the 6AV2124-1MC01-0AX0 supports 32 online languages and offers advanced features including recipe management (300 recipes, 500 data records each), 4,000 bit messages, Web browser, PDF Viewer, Sm@rtServer for remote operation, and OPC UA client/server functionality .
