Siemens 6AV2123-2GB03-0AX0 – 7″ Multi-Touch HMI Operator Panel | SIMATIC KTP700 Basic
Engineering Background
The SIMATIC KTP700 Basic series represents Siemens’ entry-level HMI platform engineered for machine-level visualization in discrete manufacturing, process control, and OEM automation. The 6AV2123-2GB03-0AX0 is the 7-inch widescreen variant featuring capacitive multi-touch technology, replacing the legacy KTP700 Basic PN (6AV2123-2GB03-0AX0) with enhanced display brightness and TIA Portal V13+ integration. It is the de-facto standard panel for SIMATIC S7-1200 and S7-1500 PLC pairings across global machine builders.
Product Positioning
Designed for procurement engineers sourcing reliable, spec-verified HMI hardware for new builds, retrofits, or MRO replacement. Konmask supplies this unit from authenticated industrial channels with full traceability — suitable for regulated environments requiring documented provenance.

Proven Application Environments
- Discrete Manufacturing: Machine tool HMI replacement, conveyor line control panels, press and stamping machine interfaces
- Food & Beverage: IP65 front seal suitable for washdown zones; paired with S7-1200 for recipe management
- Water & Wastewater: Pump station local control with PROFINET to remote I/O
- Building Automation: HVAC unit controllers, BMS local operator stations
- OEM Machine Builders: Standard panel for global machine variants requiring TIA Portal-based HMI
- MRO / Retrofit: Drop-in replacement for KTP700 Basic PN (6AV2123-2GB03-0AX0) with identical cutout dimensions
Engineering Advantages
- Capacitive Multi-Touch: 5-point touch enables gesture-based navigation (pinch-zoom, swipe) — superior to resistive predecessors
- TIA Portal Native Integration: Single-engineering-framework configuration; no separate HMI software license required for Basic panels
- PROFINET IRT Ready: Supports isochronous real-time communication for motion-synchronized HMI feedback
- IP65 Front Seal: Dust-tight and jet-water resistant — compliant with IEC 60529 for industrial enclosure mounting
- Wide Supply Voltage Range: 20.4–28.8 V DC tolerates unstable 24 V bus conditions common in legacy panel wiring
- Compact Depth (46 mm): Fits shallow enclosures; reduces panel depth requirements vs. prior-generation units
- USB Host Port: Enables project backup, firmware update, and recipe data transfer via USB stick without network access

The panel operates as a PROFINET IO controller or device depending on network topology. In standard machine configurations, the PLC acts as IO controller and the HMI connects as an additional PROFINET node. Tag communication is handled via the TIA Portal-generated HMI connection — no additional driver or OPC layer required.

Technical FAQ
Q: Is this panel compatible with S7-300 / S7-400 PLCs?
A: Yes, via PROFINET. However, TIA Portal V13+ is required for configuration. Legacy STEP 7 projects require migration to TIA Portal first.
Q: Can this replace a 6AV2123-2GB03-0AX0 (older firmware)?
A: Yes — the panel cutout dimensions and PROFINET interface are identical. Firmware can be updated via USB or TIA Portal after installation.
Q: What is the maximum number of tags supported?
A: KTP700 Basic supports up to 500 process tags (power tags) in TIA Portal WinCC Basic.
Q: Is a runtime license required?
A: No. WinCC Basic runtime is embedded in the panel hardware — no separate runtime license purchase is needed.
Q: What is the display backlight lifespan?
A: Rated at 50,000 hours MTBF at 25 °C ambient — approximately 5.7 years of continuous operation.
Q: Can I connect multiple PLCs to one panel?
A: KTP700 Basic supports connection to one PLC controller at a time via PROFINET in standard configuration.
