- 6AV6645-0AB01-0AX0 – MP277 8” Key; larger display, same MPI/PROFIBUS interface family
- 6AV6643-0AA01-1AX0 – OP277 4” variant; smaller form factor, same protocol stack
- Weintek MT8071iE – Third-party equivalent; supports SIEMENS S7 MPI/PPI protocol via driver
- Kinco MT4414T – Cost-effective alternative; supports S7-300/400 via MPI adapter
Note: Third-party replacements may require protocol converters or additional configuration. Contact Konmask for compatibility verification.
Why Choose the Original Model
- Native SIMATIC Integration: Plug-and-play with S7-200, S7-300, S7-400 via MPI/PROFIBUS — no protocol converter required
- WinCC Flexible Ecosystem: Full tag management, alarm logging, recipe handling, and trend display natively supported
- Proven Reliability: IP65-rated front panel withstands dust, coolant splash, and industrial vibration
- Long Service Life: Widely deployed in legacy systems; spare parts and repair services remain available
- Keypad-First Design: Ideal for gloved-hand operation in harsh environments where touchscreens are impractical
Typical Applications
- Machine tool control panels (CNC lathes, milling centers)
- Packaging line HMI stations
- Water treatment and pump control systems
- Conveyor and material handling automation
- HVAC and building automation control cabinets
- Pharmaceutical and food processing equipment
- Power distribution and energy management panels
System Compatibility
- SIMATIC S7-200 – via PPI/MPI protocol
- SIMATIC S7-300 / S7-400 – via MPI or PROFIBUS DP
- SIMATIC S5 – via AS511 protocol (requires configuration)
- Third-party PLCs – via RS-232 with supported driver (Allen-Bradley DF1, Modbus RTU, Mitsubishi FX)
- Configuration PC – USB Type B for project download; RS-232 for legacy transfer
Selection Guide
Use the criteria below to determine whether the 6AV6643-0BA01-1AX0 is the right panel for your application, or to identify a suitable alternative:
- Keep the OP277 6AV6643-0BA01-1AX0 if: Your system uses S7-300/400 with MPI/PROFIBUS, you need keypad operation, and your WinCC Flexible project is already developed for this panel.
- Upgrade to KTP700 Basic (6AV2123-2GB03-0AX0) if: You are migrating to PROFINET, need a touch interface, and can redevelop the HMI project in WinCC Basic V13+.
- Choose MP277 (6AV6645-0AB01-0AX0) if: You need a larger display (8”) with the same MPI/PROFIBUS interface and more user memory.
- Consider third-party alternatives if: Budget is the primary constraint and your team can handle protocol configuration and driver setup.
- Contact Konmask if: Your application has non-standard requirements — we can advise on the optimal panel selection and sourcing path.

Replacement & Compatibility FAQ
Q: Can I replace the 6AV6643-0BA01-1AX0 with a KTP700 Basic without reprogramming?
A: No. The KTP700 Basic uses PROFINET and WinCC Basic — the project must be migrated from WinCC Flexible. Panel dimensions also differ, requiring a new cutout.
Q: Is the OP277 compatible with S7-1200 or S7-1500?
A: Not natively. S7-1200/1500 use PROFINET; the OP277 does not support PROFINET. A PROFIBUS CP module on the S7-1200/1500 side may enable communication but is not officially supported by SIEMENS.
Q: Can I use a third-party HMI with my existing S7-300 MPI network?
A: Yes, provided the third-party panel supports S7 MPI protocol (e.g., Weintek, Kinco, Pro-face with appropriate driver). Verify baud rate and station address settings.
Q: What is the lead time for the 6AV6643-0BA01-1AX0?
A: In-stock units ship within 1–3 business days. For out-of-stock items, typical lead time is 2–4 weeks depending on sourcing. Contact us for real-time availability.
Q: Do you provide a datasheet or SIEMENS documentation?
A: Yes. Official SIEMENS product documentation and the WinCC Flexible compatibility matrix are available upon request.
