Application Scenarios

A European automotive parts manufacturer recently faced a classic legacy-pain scenario: one of the Siemens 6AV3627-1QL00-0AX0​ panels on a S7-300-controlled resistance-welding line suffered CCFL backlight failure—a common aging symptom in TP27 units after 60,000+ hours. With the touchscreen also showing drift, operators could no longer reliably read weld-current trends or adjust recipe parameters. Rather than re-engineering the entire cell for a TP1200 Comfort (which would require TIA Portal re-licensing, new cutout modifications, and days of downtime), the maintenance team sourced a New Old Stock 6AV3627-1QL00-0AX0. Because the panel cutout, 18 V DC supply, and MPI wiring were identical, they swapped it in under 30 minutes using the existing ProTool project file. The TP27-10​ restored full visibility—real-time trend graphs, alarm acknowledgment, and recipe editing—within the same morning shift. The facility estimated €15,000 saved in avoided downtime and re-engineering. For plants where “don’t fix what isn’t broken” applies, the 6AV3627-1QL00-0AX0​ is the pragmatic hero.

Technical Principles and Innovative Values

• Innovation Point 1: Hybrid Input Architecture.​ The 6AV3627-1QL00-0AX0​ combines an analog resistive touchscreen with numeric, alphanumeric, and hexadecimal membrane keypads—rare in modern HMIs. This gave operators tactile certainty for high-glove environments (food, pharma, heavy oil) where pure touch can misregister.
• Innovation Point 2: Multi-Port Fieldbus Flexibility.​ Beyond MPI/PROFIBUS DP, the TP27-10​ carries 1× TTY, 2× RS-232, and 1× RS-422/485 on-board. That means it can talk simultaneously to a Siemens PLC, a barcode scanner (RS-232), and a third-party drive (RS-485)—no gateway needed.
• Innovation Point 3: PC Card Slot for Recipe & Data Portability.​ The integrated PC card slot on the 6AV3627-1QL00-0AX0​ lets technicians swap recipes or pull alarm logs via ATA flash cards—a lifesaver on lines where networking the HMI back to the MES wasn’t originally planned.

Application Cases and Industry Value

Case 1 – Food & Beverage Packaging (Central Europe).​ A bottling line running S7-400 with three TP27-10​ panels hit a problem: one panel’s touch calibration drifted beyond recovery. Because the OEM had long exited the market, the plant engineer sourced a refurbished 6AV3627-1QL00-0AX0​ with fresh CCFL and re-flashed ProTool project. Downtime: 45 minutes. Cost of a full HMI migration quote: ~€28,000. Chosen path: €1,800 spare + 45 min labor. The TP27-10​ kept the line running another three years until a scheduled line rebuild.

Case 2 – Water Treatment SCADA Node (Asia-Pacific).​ A remote pumping station used the 6AV3627-1QL00-0AX0​ as a local operator node over RS-485 to a S7-300. The panel’s IP65 front and 85% relative-humidity tolerance proved critical in the semi-outdoor enclosure. After 14 years, the original was still online—only the backup battery (3.6 V optional) had been swapped twice. The municipality eventually bought two extra TP27-10​ units as shelf spares to cover the remaining 6-year design life.

Related Product Combination Solutions

The 6AV3627-1QL00-0AX0​ rarely sits alone. Common companions and migration paths include:

• 6AV3627-1LL00-0AX0 (TP27-6):​ The 6-inch sibling—same architecture, smaller cutout, useful when panel space is tight.
• 6AV3530-1AH00 (OP27-10):​ Same 10.4″ form factor but key-operated (no touch), often paired with ​ on dual-station setups where one panel is “view-only.”
• 6AV6647-0AE11-3AX0 (TP177B):​ The spiritual successor in the 277/177 generation—still ProTool / WinCC flexible, easier migration than jumping straight to Comfort.
• 6AV2124-0QC02-0AX0 (TP700 Comfort):​ Siemens’ official modern replacement, but requires TIA Portal conversion and larger cutout—plan for adapter frame.
• 6AV2124-0MC01-0AX0 (TP1200 Comfort):​ 12-inch upgrade for plants wanting more screen real estate when migrating away from .
• 6ES7972-0BB42-0XA0 (MPI Cable / Profibus connector):​ Essential for linking the 6AV3627-1QL00-0AX0​ to S7-300/S7-400 racks.
