6AV2123-2GB03-0AX0 Overview
An HMI (Human Machine Interface) panel is an industrial terminal that lets operators visualize and control machines, plants, and PLC processes. HMI panels sit in the automation hierarchy above the controller (PLC), connected via industrial fieldbus protocols such as PROFINET, providing graphical screens, alarms, recipes, and data logging at the machine front end.
Key features include the 7-inch widescreen TFT display with 65536-color rendering, dual key/touch operation (8 membrane keys with touch overlay), the ARM-based processor architecture, and 10 Mbyte of user-data memory for project storage. Flash and RAM storage are both integrated, and a hardware real-time clock maintains time-of-day data during power loss.
Technical detail: the panel's ARM processor drives the TFT graphics engine and handles communication over the PROFINET interface. Active power input is typically 5.5 W with a starting inrush I2t of 0.2 A2-s, allowing operation from compact 24V DC power supplies. Acoustic feedback is provided by a buzzer (a speaker is not fitted). One USB interface supporting up to 16 GB storage is available for archiving; RS-485, RS-422, and RS-232 serial interfaces are not present on this PROFINET-only model.
Typical applications include machine-level operator stations for S7-1200/S7-1500 PLC systems, packaging and material-handling lines, pump and HVAC skid control, and laboratory or test-bench visualization where a compact 7-inch panel is appropriate.
Design consideration: budget panel cutout and rear clearance before ordering, and confirm your engineering tool version - configuration requires WinCC Basic V13 or STEP 7 Basic V13 or later.

Typical Applications
6AV2123-2GB03-0AX0 is suitable for 6 applications: Machine-Level Operator Stations, Packaging and Material-Handling Lines, Pump, HVAC and Utility Skid Control, Retrofit and Replacement of Aging HMIs, Laboratory and Test-Bench Visualization, OEM Machine Build Standardization.
Machine-Level Operator Stations
The 6AV2123-2GB03-0AX0 KTP700 Basic is the standard operator interface for S7-1200 and S7-1500 machine controls connected over PROFINET. Its 7-inch 65536-color TFT renders screen navigation, alarm banners, and trend displays clearly, while 8 membrane keys plus touch input let operators wear gloves without losing tactile shortcuts. The ARM processor and 10 Mbyte user memory handle typical machine screens, and the 5.5 W typical power draw allows the panel to share a compact 24V DC supply with PLC I/O. Configuration from WinCC Basic V13 / STEP 7 Basic V13 keeps HMI and PLC logic in one TIA Portal project, reducing commissioning effort.
Recommended
Packaging and Material-Handling Lines
On packaging lines and conveyor systems, the 6AV2123-2GB03-0AX0 provides recipe selection, batch counters, and fault diagnostics at the line front end. The hardware real-time clock time-stamps events for traceability, and Flash storage retains recipes and alarm history across power cycles - critical for production reporting. The buzzer provides audible fault acknowledgment in noisy environments (a speaker is not fitted). Its PROFINET interface integrates directly with Siemens PLC line controllers, and the 10 Mbyte user memory accommodates multiple product recipes. One USB port up to 16 GB enables recipe backup without engineering laptop access on the line.
Recommended
Pump, HVAC and Utility Skid Control
For pump stations, HVAC skids, and utility panels, the 6AV2123-2GB03-0AX0 offers a compact 7-inch operator window with key and touch operation suited to wall- or door-mounted enclosures. The typical 5.5 W active power input and 0.2 A2-s inrush I2t impose minimal load on skid power supplies, and the hardware real-time clock supports time-based scheduling and logging displayed on-screen. Because communication runs over PROFINET, the panel links to the skid PLC with a single industrial Ethernet cable. Configuration from WinCC Basic V13 / STEP 7 Basic V13 allows screen reuse across multiple skid units, standardizing service procedures fleet-wide.
Recommended
Retrofit and Replacement of Aging HMIs
The 6AV2123-2GB03-0AX0 is frequently specified when replacing failed or obsolete Basic Panels. Siemens provides a Basic Panels migration guide describing predecessor-to-successor device replacement, and the HMI project can be reloaded over PROFINET from the TIA Portal project, preserving configuration. For panels with only cosmetic damage, service-level parts - Radwell verified keypad membranes, bezels, and touchglass sized to the KTP700 Basic (viewing area approximately 155.5 x 86.5 mm keypad / 159.5 x 92.5 mm touchglass) - restore the original unit without reprogramming. Engineers should confirm cutout dimensions and WinCC version before ordering either a new panel or repair kit.
Recommended
Laboratory and Test-Bench Visualization
In labs and test benches, the 6AV2123-2GB03-0AX0 acts as a compact HMI for controlling test rigs driven by S7-1200 controllers. The 7-inch TFT with 65536 colors displays measured values, pass/fail indicators, and simple trend curves; touch entry of setpoints keeps benchtop workflow fast, while membrane keys support repetitive start/stop actions. The 10 Mbyte user memory stores multiple test profiles as recipes, and the USB port accepts up to 16 GB media for exporting logged results. Typical 5.5 W power consumption keeps bench power supplies unburdened, and TIA Portal integration lets engineers modify screens alongside the test PLC logic.
Recommended
OEM Machine Build Standardization
Machine builders standardize on the 6AV2123-2GB03-0AX0 as a common HMI across product lines because it combines key and touch operation (covering diverse operator preferences) with a single PROFINET interface that works with all current Siemens controllers. Reusing screens from WinCC Basic V13 projects across machines shortens engineering cycles, and the common 7-inch cutout simplifies enclosure design. The integrated buzzer provides operator feedback without external sounders, and open-source software shipped on the enclosed CD satisfies license documentation requirements for OEM deliveries to regulated markets.

Key Differentiators
- Identical 7-inch hardware with dual-fieldbus option (vs 6AV2123-2GA03-0AX0)
- Lower power draw than larger Basic panels (vs 6AV2123-2MB03-0AX0)
- Key + touch redundancy (vs Touch-only HMI panels)
Design Notes
This PROFINET-only model has no RS-485/RS-422/RS-232 interfaces (0 per the Siemens data sheet). If the machine network includes PROFIBUS DP devices, order the 6AV2123-2GA03-0AX0 KTP700 Basic DP instead, or add a PROFIBUS-to-PROFINET converter. Verifying the fieldbus type before ordering is the most common source of KTP700 return shipments.
Plan the 24V DC supply around the typical 5.5 W active power input and the 0.2 A2-s starting inrush I2t. At 24V DC this is roughly 0.23 A of continuous load, comfortably within small DIN-rail supplies, but confirm headroom when the panel shares a supply with PLC, I/O, and network switches. Deriving figures: 5.5 W / 24 V is an estimate from the datasheet power figure, not a stated current spec.
Although an HMI panel has no PCB footprint, panel-cutout planning is the equivalent concern: confirm the 7-inch KTP700 Basic cutout and rear clearance (including the PROFINET connector depth and USB service access) before ordering the enclosure. Siemens provides free CAD models (STEP, STL, IGES) via TraceParts/RS for enclosure design, enabling accurate door cutout and gasket layout checks before machining.
