Product Overview
The Siemens 6AV2124-0GC01-0AX0 is a 7-inch widescreen touch-only HMI from Siemens’s SIMATIC HMI Comfort Panel series (the “Jingzhi” / 精智 line in Chinese documentation), positioned as the mid-size machine-door panel between the 6-inch KTP600/TP190 and the 9-inch TP900 Comfort. Built around an X86 processor with 12 MB of configuration memory and running Windows CE 6.0, the 6AV2124-0GC01-0AX0 is configured exclusively through TIA Portal WinCC Comfort V11 and later (V12, V13, V14, V15, V16, V17, V18 — Siemens maintained Comfort Panel support through TIA V18 before the Unified successor took over new-project recommendations). The display is a 7-inch 16:9 TFT with WVGA 800 × 480 resolution and 16.7 million colors (24-bit), LED backlit with an 80,000-hour MTBF at 25 °C and 0–100 % software-dimmable — a meaningful upgrade over the older TP177B 6-inch 256-color TFT it effectively replaced in the Siemens HMI ladder. Touch is analog resistive (single-point), chosen over capacitive for gloved-finger operation on shop floors where operators wear cotton or nitrile gloves — a deliberate Siemens decision for the Comfort series, reserving projected-capacitive for the later Unified line.
The Siemens 6AV2124-0GC01-0AX0 carries a PROFINET interface with a 2-port built-in switch (allowing line-topology daisy-chaining without an external switch), plus an RS485 port that can operate as MPI or PROFIBUS DP — making it backward-compatible with S7-300/400 MPI networks and forward-compatible with S7-1200/1500 PROFINET plants from the same cutout. Two USB 2.0 host ports (for mouse/keyboard/service stick during commissioning) and one USB Mini-B device port (for PC connection) sit alongside two SD card slots used for project transfer, recipe storage, alarms, and logging. Power is 24 V DC (19.2–28.8 V range, 0.5 A rated, 12 W typical), fanless passive cooling, front IP65 / NEMA 4X indoor (with gasket seal on cabinet cutout), rear IP20, operating 0 to +50 °C vertical (up to 35° tilt allowed). Mechanical envelope is 214 × 158 × 63 mm with a 190 × 134 mm flush-mount cutout, weight 1.49 kg. From a lifecycle standpoint, Siemens has placed the 6AV2124-0GC01-0AX0 into “Phase-Out Announced” status with successor 6AV2128-3GB06-0AX1 (TP700 Unified Comfort) — meaning new-project builds should target Unified, but the installed base of Siemens 6AV2124-0GC01-0AX0 across packaging lines, plastics machines, assembly cells, and process skids remains enormous, and genuine/new-surplus/refurb units are still actively traded as critical spares.

Main Features and Advantages
The Siemens 6AV2124-0GC01-0AX0 earned its place as the volume leader in the Comfort Panel lineup because 7 inches hits the ergonomic sweet spot for machine-door mounts — large enough for alarm lists, recipe pages, and trend views that a 6-inch panel fights for, yet small enough to fit standard 200 mm-class cutouts without reinforcing the door. Several design decisions differentiate the 6AV2124-0GC01-0AX0 from both its predecessors (TP177B/TP270) and its successor (TP700 Unified).
7″ 16:9 WVGA with 16M colors and dimmable LED. The jump from the TP177B’s 6″ 4:3 320×240 / 640×480 and 256-color palette to the Siemens 6AV2124-0GC01-0AX0‘s 800×480 WVGA 16M-color TFT is visually immediate — gradients in trend charts, color-coded alarm severities, and PNG/JPEG machine graphics render without posterization. The LED backlight is dimmable 0–100 % via script or HMI tag, which matters in low-light cells (pharma cleanrooms, night-shift packaging) where a fixed-bright panel washes out the operator’s vision. 80,000-hour MTBF at 25 °C translates to roughly 9 years at 24/7 before half-brightness — by which point most plants have already refreshed the machine.
PROFINET with 2-port built-in switch. The 6AV2124-0GC01-0AX0 doesn’t consume an external switch port per HMI — the PROFINET interface has two RJ45s acting as a 2-port switch, letting the HMI sit inline between the S7-1500/1200 and the next device (e.g., a G120 drive or ET 200SP rack). This reduces panel-component count and cable length in machine cabinets where the HMI is the natural network break-point. MRP (Media Redundancy Protocol) is supported, and the port LEDs report link/activity at a glance.
MPI/PROFIBUS DP on the same RS485 physical. The second port auto-configures as MPI (to talk S7-300/400 PG/OP channel) or PROFIBUS DP slave if the application needs it — useful for mixed-fleet plants where a new Siemens 6AV2124-0GC01-0AX0 is slotted onto an older S7-400 MPI backbone while the same panel model also deploys on greenfield S7-1500 PROFINET. One spare BOM covers both vintages.
Dual SD card slots for project + data separation. Unlike panels that give you one SD card fighting for project transfer vs. recipe/alarm logging, the 6AV2124-0GC01-0AX0 provides two slots — commonly one holds the project/OS image (SD/SDHC up to 32 GB Class 4+) and the second handles CSV recipe files, alarm buffers, and trend logs. For packaging machines where recipe changeovers happen 20× per shift and audit-trail CSVs must survive a panel swap, having dedicated slots avoids the “pull the wrong card” mistake during a midnight restore.
Resistive touch over capacitive for industrial reality. The Siemens 6AV2124-0GC01-0AX0 uses analog resistive — single-point, works with any glove, any stylus, doesn’t care about moisture on the screen (common near washdown zones or coolant mist). Capacitive (as on Unified) is nicer for smartphone-like swipe, but resistive is the pragmatic choice for plants where operators wear cotton gloves and the panel sits 18 inches from a coolant spray. Siemens made the resistive/capacitive split deliberately: Comfort = resistive, Unified = projective capacitive.
X86 + 12 MB config + WinCE 6.0 = stable runtime. The X86 core and 12 MB config memory handle moderately complex WinCC Comfort projects — multiple screens, VBScript fragments, ActiveX controls (within CE 6.0’s limited ActiveX set), and SmartServer web access for remote VNC viewing. 12 MB sounds small by today’s tablet standards, but WinCC Comfort compiles efficiently and a typical TP700 project lands 3–6 MB; the 6AV2124-0GC01-0AX0 doesn’t choke on well-structured projects. The hardware RTC with ~6-week backup (supercap + battery assist depending on revision) keeps timestamps across power cycles — important for alarm logs in batch plants.
Fanless, IP65 front, NEMA 4X indoor. Passive cooling eliminates the fan-failure path. Front gasket seals to a 190 × 134 mm cutout for IP65 / Type 4X (indoor) — hose-down rated for the operator side. Rear is IP20, so the cabinet interior must be controlled-environment, which is normal for machine-door mounts. The Siemens 6AV2124-0GC01-0AX0 is built for the operator side of the door, not the washdown-wall side (that’s the Comfort Outdoor variants, which have wider temp -30…+60 °C).
