Siemens 6AV2124-0UC02-0AX1 HMI Touch Panel – SIMATIC Comfort Series Spare Part

Technical Specifications

Solving the Long Lead-Time Hardware Crisis

Facilities that have extended the service life of their SIMATIC installations by 5–10 years beyond the original design horizon consistently cite three practices: maintaining a dedicated HMI spare pool, establishing a firmware version registry so replacements are configured identically to the failed unit, and partnering with a specialist supplier capable of sourcing units outside the standard distribution network. DriveKNMS operates specifically within that third category.

Condition & Reliability Assurance

Every 6AV2124-0UC02-0AX1 unit processed through DriveKNMS undergoes a structured five-stage inspection before dispatch:

• Visual and mechanical inspection: Housing integrity, connector pin condition, and front panel glass checked for stress fractures or corrosion ingress.
• Backlight and display verification: Full-screen illumination test to identify uneven backlighting, dead zones, or pixel degradation.
• Touch calibration test: Grid-pattern touch accuracy verification across the full active area.
• Power-on functional test: Unit is powered at rated 24 V DC and booted to confirm OS integrity and interface responsiveness.
• Firmware version documentation: The installed WinCC Comfort runtime version is recorded and provided with the unit, enabling the receiving engineer to match or update to the target version before installation.

Key Features for System Maintenance

• Drop-in replacement: The 6AV2124-0UC02-0AX1 is a direct hardware substitute for any unit of the same part number. No controller-side reconfiguration is required — the project file transfers via USB or SD card.
• No re-engineering cost: Existing WinCC Comfort project files load directly onto the replacement unit. Operator screens, alarm lists, and trend displays are preserved without modification.
• PROFINET and MPI/PROFIBUS dual connectivity: Supports both legacy MPI/PROFIBUS installations and modern PROFINET architectures, making it viable across a wide range of SIMATIC system generations.
• IP65 front protection: Maintains the original ingress protection rating, preserving panel cutout compliance and environmental certification without additional sealing work.

How do I confirm the unit is new or properly refurbished?
New units are supplied in original Siemens packaging with intact factory seals. Refurbished units are supplied with a DriveKNMS inspection report detailing each stage of the QA process and the firmware version installed. We do not ship units that have not passed all five inspection stages.

Should I hold more than one spare?
For production environments running two or more shifts, holding a minimum of two units is standard practice. HMI panels in high-cycle environments — where operators interact with the screen continuously — experience accelerated touch layer wear. A second spare eliminates the risk of a second failure occurring during the procurement cycle for the first replacement.
