6AV2123-2GA03-0AX0
ActifSIMATIC KTP700 Basic DP 7-inch Key+Touch HMI
Siemens SIMATIC KTP700 — 7-inch touchscreen replacing physical buttons.
Applications courantes
The trend in modern machines: replace rows of physical buttons with a single touchscreen HMI. The KTP700 provides virtual buttons, indicators, alarms, and trending on one 7-inch display. TIA Portal configurable. Found on packaging machines, food processing lines, and CNC equipment. Physical e-stop is still required alongside the touchscreen.
Research Notes
1. Overview
The Siemens SIMATIC HMI KTP700 Basic DP (6AV2123-2GA03-0AX0) is a 7-inch Basic-line operator panel combining a widescreen touchscreen with 8 freely-configurable tactile function keys (F1–F8) — the "Key & Touch Panel" concept, which is why it belongs in a button index as much as an HMI. This specific order number is the DP variant, with a PROFIBUS DP (RS-485) interface (the PROFINET variant is 6AV2123-2GB03-0AX0). It's configured with WinCC Basic / TIA Portal and used as the local operator interface for SIMATIC PLCs. (Data-quality note: this DP model is PROFIBUS DP, not "PROFINET / EtherNet-IP" as previously stored.)
2. User Sentiment
The KTP700 Basic is a hugely popular entry-level HMI — valued for the reliable 7" display plus real tactile function keys (useful with gloves or for fixed actions), tight TIA Portal integration, and Siemens ecosystem support. Common notes: Basic panels are feature-limited versus Comfort panels (no advanced scripting/archiving), and buyers must pick the correct bus variant — DP (PROFIBUS) vs PN (PROFINET) — for their PLC network (a frequent ordering mistake).
3. Real-World Applications
Machine-level operator interface for SIMATIC S7-1200/1500 (and legacy) PLCs — status display, setpoint entry, alarms, and the 8 function keys mapped to fixed machine actions. The DP version suits existing PROFIBUS networks.
4. Technical Specifications
- Type: SIMATIC HMI Basic Panel, 7" — touchscreen + 8 tactile function keys
- Display: 7" TFT widescreen, 800×480, 64K colors, LED backlight
- Interface: PROFIBUS DP (RS-485) — this is the DP variant (PN variant = 2GB03)
- Mounting: panel mount, cutout ~197×141 mm; IP65 (front)
- Config software: WinCC Basic (TIA Portal)
- Approvals: UL, CE, ATEX Zone 2 (per listing)
5. Ordering & Compatibility
Order number 6AV2123-2GA03-0AX0 = KTP700 Basic DP (PROFIBUS). For a PROFINET/Ethernet network, order the PN variant 6AV2123-2GB03-0AX0 instead. Programmed via TIA Portal (WinCC Basic). Pairs with SIMATIC S7 PLCs; service parts include the touch panel, front film, and clips.
6. Known Issues
No notable reliability issues. The key gotcha is bus-variant selection — the "-2GA03-" (DP) and "-2GB03-" (PN) order numbers look nearly identical but are PROFIBUS vs PROFINET, which must match your PLC network. Basic-panel feature limits (vs Comfort) and standard HMI cautions (backlight lifetime, firmware/TIA version match) also apply.

Référence rapide d'installation
Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Dépannage
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
