Siemens 6AV2123-2GB03-0AX0 SIMATIC HMI KTP700 Basic, Basic Panel with 7" TFT Display — Specifications, Pricing, and Selection Guide

Controls engineers and OEM panel builders searching for the Siemens 6AV2123-2GB03-0AX0 are typically at the same decision point: they have already committed to a Siemens S7-1200 or S7-1500 PLC, they need a machine-level operator interface that can go in fast and stay reliable, and they want to confirm this specific SKU — not a larger, more expensive panel — is the right call. The SIMATIC HMI KTP700 Basic is a 7-inch TFT touchscreen panel with a 65536-color display, 800x480 pixel resolution, four programmable soft buttons, and a PROFINET RJ45 interface, configured entirely within the TIA Portal ecosystem using WinCC Basic V13 or later.

Who Should Buy the 6AV2123-2GB03-0AX0 — and Who Shouldn't

The SIMATIC HMI KTP700 Basic is the right panel if your application matches the following criteria:

  • Your machine enclosure accommodates a 7-inch display — not a 4-inch (KTP400) or 12-inch (KTP1200) panel
  • Your PLC network runs PROFINET over Ethernet — if PROFIBUS DP is your infrastructure, the correct part is 6AV2123-2GA03-0AX0
  • Your engineering team has WinCC Basic V13 or later available in TIA Portal for project configuration
  • Your control cabinet provides 24 VDC power supply for the panel
  • Your operator workflow involves straightforward start, stop, reset, and parameter display — not multi-product recipe management or data archiving
  • Your lead time budget can absorb 2–4 weeks from distributor stock or up to 6–10 weeks for made-to-order quantities

If your process requires automatic recipe switching, user login management, or historical data archiving, this Basic Panel tier will not cover those requirements — the Comfort Panel series is the correct upgrade path.

What the KTP700 Basic Actually Does in a Running System

The 6AV2123-2GB03-0AX0 is a machine-level operator interface — it sits between the machine operator and the PLC. It receives real-time process data from a Siemens S7-1200 or S7-1500 PLC over a PROFINET Ethernet connection, renders that data on a 7-inch TFT color touchscreen at 800x480 pixel resolution, and transmits operator commands — button presses, numeric entries, setpoint adjustments — back to the PLC. The panel itself executes no control logic; it is purely a visualization and input device.

Within the SIMATIC HMI product family, the KTP700 Basic occupies the entry-level tier above dedicated keypad units and well below the Comfort Panel series. It supports bit-level and word-level data display, threshold-based and bit-triggered alarms with time-stamped event logging at limited capacity, and multi-language display configured in WinCC Basic. What it does not do — and this is a firm boundary — is store historical data archives, manage automatic recipe switching, or enforce user-level access control. For single-machine or small production cell applications with straightforward operator workflows, those omissions are irrelevant. For batch manufacturing with multi-product traceability requirements, they matter significantly.

The panel mounts to a machine enclosure or control cabinet panel cutout using standard fasteners, draws 24 VDC from the cabinet power supply at approximately 2–3 amps, and connects to the PROFINET network via a single standard RJ45 port using Cat5e or Cat6 shielded Ethernet cable. The front panel carries an IP65 protection rating — sealed against dust and low-pressure water jets — making it suitable for production floor environments including food and beverage and pharmaceutical facilities.

Where the 6AV2123-2GB03-0AX0 Fits in a Typical PROFINET Architecture

The KTP700 Basic sits at the operator-interface layer of the control system, downstream of the PLC and upstream of the machine operator. Understanding its position in the signal chain helps during network planning and IP address allocation.

  • Engineering workstation running TIA Portal and WinCC Basic — creates screen layouts and maps tags to PLC variables, then downloads the project to the panel via Ethernet
  • Siemens S7-1200 or S7-1500 PLC — executes machine control logic; exposes process data and accepts commands via PROFINET network
  • Industrial managed Ethernet switch — connects PLC and HMI panel on the same PROFINET subnet; switch with PROFINET time-sync capability is recommended for process control applications
  • 6AV2123-2GB03-0AX0 KTP700 Basic panel — displays live PLC data, accepts operator input, sends commands back to PLC; assigned a static IP address on the PROFINET subnet
  • Machine operator — interacts with the touchscreen and four programmable soft buttons to start, stop, reset, and adjust machine parameters within the ranges the PLC logic permits

Industries and Machine Types That Specify the KTP700 Basic

Food and beverage production lines are among the most common placements for the 6AV2123-2GB03-0AX0. Bottling and filling lines use the panel to display real-time speed, fill level, and production count, with soft buttons mapped to start, stop, and reset commands. The IP65 front panel rating supports washdown-adjacent environments where splash exposure is routine.

Pharmaceutical and chemical handling applications use the KTP700 Basic for tablet press monitoring — batch number entry, pressure and temperature display, and alarm annunciation. The panel's alarm log with time-stamped events satisfies basic documentation requirements for batch traceability, though facilities requiring full electronic batch records at the HMI level will need to evaluate Comfort Panel capabilities.

Discrete manufacturing environments — injection molding, motor and conveyor control, assembly line stations — frequently specify this panel for its combination of 7-inch visibility, low cost relative to the 10-inch and larger tier, and straightforward WinCC Basic configuration. An injection molding machine operator can view cycle time, cavity temperature, and active alarms on a single screen without navigating complex menu trees.

Water and wastewater treatment plants use the panel for pump status monitoring, tank level visualization, and chemical dosage display. The panel handles the time-stamped event log for basic operational records, and the PROFINET connection to the plant PLC keeps configuration simple for facilities already running Siemens control infrastructure.

Application Typical Deployment
Bottling and filling line Single panel per machine cell; displays fill level, speed, and production count; soft buttons for start/stop/reset
Pharmaceutical tablet press Batch number entry, pressure and temperature display, alarm annunciation; PROFINET connection to S7-1200 or S7-1500

Expert Verdict: Honest Assessment for Purchase-Ready Engineers

The 6AV2123-2GB03-0AX0 earns its position in the SIMATIC HMI lineup precisely because it does not try to be everything. For a controls engineer specifying a panel for a single-machine installation with a Siemens S7-1200 or S7-1500 PLC already on the BOM, this is the lowest total cost of ownership path that still delivers industrial-grade reliability, genuine PROFINET integration, and a screen large enough to display meaningful process data without requiring operators to scroll or navigate complex menus. The 7-inch, 800x480 pixel, 65536-color TFT display handles the visualization workload for the vast majority of discrete manufacturing and process monitoring applications. The four programmable soft buttons give operators tactile confirmation in environments where gloved hands make touchscreen-only interfaces problematic. WinCC Basic configuration inside TIA Portal means the same engineering environment the team already uses for PLC programming handles the HMI project — no separate software license, no separate learning curve.

Where the KTP700 Basic genuinely falls short is well-defined. No built-in user login means access control must be implemented in PLC logic if the application requires it — manageable for experienced integrators but worth acknowledging at specification time. No automatic recipe management means that batch manufacturing applications with multiple product configurations will hit a ceiling quickly; the Comfort Panel series exists for exactly that scenario. And the 7-inch display, while the right size for single-machine applications, becomes limiting when operators need to monitor four or five simultaneous process variables with trend charts — at that point the KTP1200 Basic at approximately 30–50% additional cost is the honest recommendation. For PROFIBUS infrastructure, remember that this specific model number is the PROFINET variant; 6AV2123-2GA03-0AX0 is the PROFIBUS equivalent.

From a procurement standpoint, lead times of 2–4 weeks from distributor stock are realistic for standard demand. Projects that cannot absorb a 6–10 week made-to-order window should confirm stock availability before finalizing build schedules. Refurbished certified units are available at approximately 30–40% cost reduction with a 6-month warranty — a legitimate option for non-production-critical or temporary installations. OEM builders ordering 100 or more units typically access volume pricing 20–30% below single-unit rates. If this matches your system requirements, view current stock and pricing at LeadTime.ca.

Wiring and Installation: What to Verify Before You Mount the Panel

  • Confirm 24 VDC power supply is available in the control cabinet and verify polarity before connecting — the panel has no reverse-polarity protection, and incorrect wiring causes permanent damage; use a multimeter on the terminals before energizing
  • Use Cat5e or Cat6 shielded Ethernet cable for the PROFINET connection and terminate with industrial-grade RJ45 connectors per IEC 61076-2-109; maximum cable run is 100 meters per segment without a managed switch in between
  • Route 24 VDC power and Ethernet cables separately from AC high-voltage circuits in the cabinet to avoid interference
  • Ensure IP65 front panel sealing is maintained during mounting — verify the panel gasket is correctly seated and use cable glands as specified in Siemens installation documentation
  • Confirm case grounding via the control cabinet DIN rail or cabinet frame to provide a low-impedance return path before powering on

TIA Portal Configuration and WinCC Basic Project Download Overview

The 6AV2123-2GB03-0AX0 is configured entirely within TIA Portal using WinCC Basic V13 or later — no separate engineering platform is required. The configuration and download process follows this general flow:

  • In WinCC Basic, create the screen layout using the drag-and-drop editor; map hardware tags to PLC variables using symbolic naming with PROFINET-supported data types including DINT, REAL, and arrays; organize screens by machine state — startup, run, alarms, maintenance — for operator clarity
  • Assign the panel's IP address, subnet mask, and gateway either through the panel's touch screen System Setup menu or via the WinCC Basic network configuration tool; the PROFINET network LED on the RJ45 port should show green once the address is correctly configured and a link is active
  • Download the completed WinCC Basic project to the panel via Ethernet by selecting the target device (6AV2123-2GB03-0AX0) in the download menu, verifying the target IP address, and initiating transfer — the process typically completes in 2–5 minutes, after which the panel reboots and loads the new project automatically
  • Configure alarm thresholds and bit-triggered events in WinCC Basic; note that the Basic Panel tier provides a time-stamped alarm log at limited storage capacity — for applications requiring extended historical alarm records, evaluate Comfort Panel capabilities
  • After project download, verify all screens display correctly, confirm PLC communication is active by observing live data updates, and test each soft button mapping before signing off on commissioning; document the assigned IP address and network parameters in the facility asset management system

What Engineers Get Wrong When Ordering This Part

Before placing the order, run through this checklist drawn from the most common specification errors on this SKU:

  1. Verify PROFINET protocol required — if PROFIBUS infrastructure exists, order 6AV2123-2GA03-0AX0 instead
  2. Confirm 7" display size fits machine enclosure (do not confuse with KTP400 at 4" or KTP1200 at 12")
  3. Check that WinCC Basic V13 or later is available in your engineering environment (required for configuration)
  4. Ensure 24 VDC power supply available on machine (standard requirement for this panel)
  5. Verify PROFINET network cable and RJ45 connector availability (standard Ethernet, not proprietary)
  6. Confirm no requirement for integrated data archive or recipe manager (basic model lacks these; use Comfort Panel if needed)
  7. Check supply voltage tolerance matches your control cabinet (24 VDC nominal)

Frequently Asked Questions

Does the 6AV2123-2GB03-0AX0 work with both S7-1200 and S7-1500 PLCs?

Yes. The KTP700 Basic communicates via PROFINET and integrates directly with both the S7-1200 and S7-1500 families through TIA Portal without additional gateways. Tag mapping and screen configuration are handled entirely within the WinCC Basic environment in TIA Portal V13 SP1 or later. No third-party middleware or protocol converter is required for either PLC family.

What is the realistic lead time for the 6AV2123-2GB03-0AX0 in 2025–2026?

For standard in-stock orders through distributors, 2–4 weeks is typical. Made-to-order or lower-volume requests run 6–10 weeks. If your project schedule cannot absorb a 6–10 week window, confirming stock availability before finalizing your build timeline is strongly recommended. Maintaining one or two spare panels locally eliminates this risk for production-critical lines.

Can the KTP700 Basic handle recipe management for multi-product machines?

The Basic Panel tier supports manual parameter download only — there is no automatic recipe switching. An operator can enter parameters manually on screen, but the panel cannot store and automatically load product-specific parameter sets. If your machine runs multiple product configurations that need operator-selectable recipe recall, the Comfort Panel series is the correct choice. This is a firm architectural boundary within the SIMATIC HMI product family.

What version of WinCC Basic is required, and does it require a separate license?

WinCC Basic V13 or later is required for configuration. It is integrated within TIA Portal V13 SP1 or later — there is no separate standalone engineering platform required. For best security patch coverage, WinCC Basic V14 or later is recommended. Verify your TIA Portal version before beginning the project to avoid compatibility issues at download time.

Is the PROFIBUS variant of this panel a direct drop-in replacement?

Electrically and dimensionally, the PROFIBUS variant (6AV2123-2GA03-0AX0) is similar, but it uses a PROFIBUS DP connector rather than the RJ45 PROFINET port of the 6AV2123-2GB03-0AX0. The two are not interchangeable without corresponding changes to the PLC network infrastructure and WinCC Basic project configuration. Verify your network protocol before ordering — swapping variants after installation requires replanning the network connection and reconfiguring the panel project.

What happens if the panel loses power during a project download?

If power is interrupted during a WinCC Basic project download via Ethernet, the panel may fail to boot the new project. In most cases, the panel retains the previously downloaded project in internal flash and returns to it on the next power cycle. If the flash is corrupted, re-downloading the project via Ethernet or USB restores normal operation. Always complete download cycles on a stable power supply and avoid interrupting the transfer sequence.
