Siemens 6AV2124-0QC02-0AX0 SIMATIC HMI TP1500 Comfort Panel — Specifications, Alternatives, and Obsolescence Guide

If you have landed here with a catalog number in hand, you are likely facing one of two situations: a failed panel on a running production line that needs a replacement fast, or a capital project where you are deciding whether to stock the legacy 6AV2124-0QC02-0AX0 or migrate to its 2023 successor. This is a 15-inch widescreen industrial HMI touch panel running Windows CE 6.0, configured via WinCC Comfort V11 SP2, and powered by 24V DC — and it has been blocked for new delivery since October 1, 2018. That single fact changes every purchase decision downstream of this page.

If you have already confirmed this is the right part and you need spare-parts pricing and current availability, check the 6AV2124-0QC02-0AX0 product page at LeadTime.ca — we ship worldwide and can advise on lead time before you commit to a build.

Who Should Order the 6AV2124-0QC02-0AX0 — and Who Should Not

The SIMATIC HMI TP1500 Comfort Panel in the 0AX0 revision is the right spare part if all of the following apply to your situation:

  • Your application specifically requires a 15-inch widescreen format at 1280x800 resolution — smaller TP700 or larger TP1900 displays do not fit your cabinet cutout or operator ergonomic requirement
  • Your control cabinet supplies 24V DC and falls within the 19.2 to 28.8 V DC permissible range — this panel accepts no AC input
  • Your facility already runs WinCC Comfort V11 SP2 and your engineering team does not need to migrate to a newer TIA Portal version
  • PROFINET IO or PROFIBUS DP/MPI connectivity is what your PLC network requires — no other fieldbus protocol is natively supported
  • Your maintenance strategy is spare-parts replacement, not system upgrade — short project lifecycle or limited expansion plans justify end-of-life pricing risk
  • IP65 front panel protection meets your washdown or dust environment; IP67 or higher is not required

If you are building new, expanding a system, or running TIA Portal V16 or later as your standard engineering platform, the correct choice is the successor model 6AV2124-0QC02-0AX2, which entered the market in March 2023 with updated Windows CE and full TIA Portal V16 Update 6 and V17 Update 6 compatibility.

What the SIMATIC HMI TP1500 Comfort Panel Actually Does in Your System

The Siemens 6AV2124-0QC02-0AX0 is a 15-inch widescreen capacitive touch panel that serves as the primary operator interface between a human and an automated control system. Its job is specific: it collects touch-based operator commands, delivers real-time visual feedback about system status, and communicates with an upstream PLC — typically via PROFINET IO or PROFIBUS DP — translating raw process data into readable alarms, trend displays, batch parameters, and setpoint controls.

The panel runs Windows CE 6.0 and carries 24 MB of user data memory for HMI application projects built in WinCC Comfort V11 SP2. With a display resolution of 1280x800 pixels at 16.7 million colors, it handles multi-screen process visualization, recipe management, alarm logging to printer or file, and network camera integration without additional hardware adapters. The hardware real-time clock with battery backup supports timestamped event logging relevant to FDA 21 CFR Part 11 and ISO documentation environments.

Two key facts define every purchase conversation about this model: the aluminum enclosure with IP65 front and NEMA Type 4/4x rating makes it physically suited to food, pharma, and chemical washdown environments; and the end-of-life status since October 2018 means you are sourcing from shrinking global spare-parts inventory, not a live production run.

Where the TP1500 Comfort Sits in a Typical SIMATIC Architecture

The 6AV2124-0QC02-0AX0 occupies the visualization and operator control layer — between the PLC network and the human operator. It does not perform control logic itself; it reads from and writes to the PLC tag database in real time.

  • Engineering workstation running WinCC Comfort V11 SP2 compiles and downloads the HMI application to the panel via Ethernet or USB
  • Siemens SIMATIC PLC (S7-300, S7-400, S7-1200, or S7-1500) connects to the panel via PROFINET IO on one of the two integrated Ethernet switch ports, or via the RS485/RS422 port for PROFIBUS DP/MPI legacy networks
  • The TP1500 Comfort panel displays live process values, accepts operator input, generates alarms, and logs events to internal memory, USB stick, or SD card
  • A second Ethernet port on the integrated switch can chain to additional HMI panels or networked I/O devices without an external switch
  • Printer, USB peripherals, and network cameras connect directly to the panel's two USB 2.0 ports for local output and monitoring

Industries and Applications Where This Panel Is Deployed

Food and beverage processing facilities use this panel as the operator touchpoint for recipe-driven batch control — displaying ingredient ratios, fill levels, temperature setpoints, and CIP cycle status on a screen large enough for gloved operators to use reliably at line speed.

Pharmaceutical manufacturers rely on the TP1500 Comfort's alarm and event logging capabilities for compliance documentation. The ability to log to printer, PDF, and HTML file formats supports FDA 21 CFR Part 11 audit trails when properly configured.

Water treatment and chemical blending plants deploy this panel for continuous process visualization where operators need to monitor multiple sensor values simultaneously across a single screen without page-switching — exactly what the 1280x800 canvas at 16.7 million colors is sized to handle.

Maintenance-driven spare-parts users represent the largest buyer segment for the 0AX0 revision today: plants that standardized on this model across multiple lines and need drop-in replacements that require zero application reconfiguration, preserving the existing WinCC Comfort V11 project without retesting.

Application Typical Deployment
Food and Beverage Batch Control Panel-mounted at line station; displays recipe parameters, fill levels, and CIP status via PROFINET to S7-1500 PLC
Pharmaceutical Compliance Logging Cabinet-mounted; logs alarms and events to USB stick and printer for FDA 21 CFR Part 11 documentation
Water Treatment Process Visualization Control room installation; continuous multi-sensor display connected to S7-300 via PROFIBUS DP
Packaging Machine HMI OEM machine-mounted; operator touchpoint for speed, format change, and fault acknowledgment
Legacy System Spare-Parts Replacement Drop-in panel swap on existing Siemens SIMATIC installations; preserves WinCC Comfort V11 application
Chemical Blending Control Hazardous-area adjacent panel with IP65 front protection; interfaces to S7-400 via PROFINET IO

Expert Verdict: Is It Worth Buying an End-of-Life HMI Panel in 2025?

The 6AV2124-0QC02-0AX0 earns its place in the spares inventory of any facility that built its SIMATIC infrastructure on WinCC Comfort V11 between 2010 and 2018. The 15-inch aluminum-enclosed panel at IP65 is a physically durable unit: the 80,000-hour backlight MTBF at 25°C means panels installed at commissioning are only now approaching end-of-backlight life in 24/7 facilities, and the 0 to 40°C operating range covers the vast majority of industrial control room and panel-mount environments. The two-port integrated Ethernet switch, USB 2.0 ports, and dual SD slots remain genuinely useful in the field — they eliminate external networking hardware on many installations and that practical advantage has not disappeared because the model is obsolete.

Where this model has real limits: the Windows CE 6.0 operating system is end-of-life at Microsoft, meaning no security patches are available. In any facility pursuing IEC 62443 cybersecurity certification or with IT mandates about network-connected devices, this panel requires network isolation from corporate and internet-facing infrastructure — that is not a workaround, it is a hard constraint. The WinCC Comfort V11 SP2 configuration requirement also creates a practical trap: if your engineering workstations have been upgraded to newer TIA Portal versions as the rest of the facility modernizes, you may need to maintain a legacy engineering PC solely to support this panel revision. Factor that into total cost of ownership honestly. If any of those constraints are blockers, the 6AV2124-0QC02-0AX2 successor entered the market in March 2023 with updated software compatibility and should be the default choice for new work.

From a procurement standpoint, spare-parts pricing for end-of-life Siemens HMI panels can deviate significantly from original list price as global stock depletes — and lead times are less predictable than for current-production parts. The right move for facilities with more than two or three of these panels in the installed base is to buy spare inventory now rather than wait for a failure event. If this matches your system requirements and you need firm pricing before a capital approval, view current stock and pricing for the 6AV2124-0QC02-0AX0 at LeadTime.ca — we source globally and can advise on realistic lead time before you commit.

Wiring and Installation — What to Verify Before You Mount This Panel

  • Confirm the 24V DC supply in your cabinet falls within the 19.2 to 28.8 V DC permissible range before connecting; this panel accepts no AC input and overvoltage will damage the unit
  • Connect the panel frame to the control cabinet earth bus per IEC standards; this is a Class I device and protective earth is mandatory, not optional
  • Install upstream overcurrent protection (circuit breaker or fused disconnect) in the 24V supply circuit; the panel itself has no integrated breaker and the rated current is 1.5 A typical
  • For PROFINET connections, use CAT5e or CAT6 shielded twisted-pair cable; the integrated two-port Ethernet switch allows daisy-chaining to a second networked device without an external switch, and maximum segment length per PROFINET standard is 100 meters
  • For PROFIBUS DP/MPI connections via the RS485/RS422 port, verify that end-of-segment termination resistors are correctly installed and that the PROFIBUS address assigned in the PLC configuration matches the HMI device address in WinCC; incorrect address or missing termination are the two most common commissioning failures on legacy serial networks

What Engineers Get Wrong When Ordering This Part

The suffix digits in this catalog number are not interchangeable — each revision has different software and driver requirements. Before finalizing your purchase order, verify every item on this checklist:

  1. Verify model number includes "0AX0" suffix (current brief), not "0AX1" or "0AX2" (different revisions with different Windows CE versions and driver support).
  2. Confirm 15-inch widescreen (1280x800) is required; do not substitute 7-inch or 22-inch models.
  3. Check that 24V DC supply is available in your control cabinet; this unit does not accept AC input.
  4. Ensure WinCC Comfort V11 SP2 or compatible configuration software is in use; newer TIA Portal versions may not support this legacy panel.
  5. Verify PROFINET or PROFIBUS DP/MPI connectivity is needed; confirm your PLC supports these protocols before ordering.
  6. Document that this model is end-of-life for new delivery; confirm spare-parts only strategy meets your maintenance roadmap.

If any item on this checklist raises a question before you order, contact LeadTime.ca — our team can cross-reference your application requirements against the correct revision and confirm availability worldwide.

Frequently Asked Questions

Can I use a 6AV2124-0QC02-0AX2 as a direct drop-in replacement for my failed 0AX0 panel without modifying my WinCC project?

The 0AX2 successor uses an updated Windows CE version and revised driver support compared to the 0AX0. While the physical format and 15-inch screen size are identical, existing WinCC Comfort V11 SP2 applications will require recompilation and validation on the new platform before production deployment — it is not a zero-effort swap. If preserving the exact existing application without retesting is a hard requirement, sourcing an 0AX0 spare panel is the lower-risk path in the short term.

The 6AV2124-0QC02-0AX0 has been end-of-life since October 2018 — can I still buy one, and what will it cost?

Siemens continues to make the 0AX0 available as a spare part through authorized channels, though new delivery orders were blocked in October 2018. Spare-parts pricing can deviate from the original list price as global inventory depletes. Lead times from distributor stock are typically shorter than direct Siemens orders, but availability varies. Check current pricing and stock at LeadTime.ca for a firm quote before committing.

Does the TP1500 Comfort support PROFINET IRT (isochronous real-time)?

The 6AV2124-0QC02-0AX0 includes two Industrial Ethernet ports with an integrated switch and supports PROFINET IO and IRT protocols. Verify the exact IRT support level against the Siemens datasheet for your specific application timing requirements, as IRT support differences between the 0AX0 and 0AX2 revisions should be confirmed before a migration decision.

My facility is pursuing IEC 62443 cybersecurity compliance — is the Windows CE 6.0 platform on the 0AX0 a problem?

Windows CE 6.0 is end-of-life at Microsoft, meaning security patches are no longer issued. For IEC 62443-compliant facilities or any installation with IT-mandated network security requirements, Siemens recommends network isolation for this panel — do not expose it to corporate networks or internet-facing infrastructure. If cybersecurity certification is a hard project requirement, the 0AX0 revision warrants careful review with your security team before deployment; the 0AX2 successor or a current-generation panel may be more appropriate.

What happens to the real-time clock if the panel loses 24V DC power for an extended period?

The hardware real-time clock has a battery backup with an approximately 6-week retention period in an unpowered state. The battery is non-replaceable by the end user. If the panel is stored or unpowered for longer than 6 weeks, the clock will require manual reset after power restoration. For applications requiring accurate timestamps in compliance logs, ensure a continuous 24V DC supply or document the clock-reset procedure in your maintenance protocol.

Can the 6AV2124-0QC02-0AX0 connect to non-Siemens PLCs?

The panel's primary communication paths — PROFINET IO and PROFIBUS DP/MPI — are Siemens-optimized protocols. While some non-Siemens PLCs support PROFINET, native integration is strongest with SIMATIC S7-300, S7-400, S7-1200, and S7-1500 controllers. If your facility uses mixed-brand controllers (Rockwell, Mitsubishi, FANUC), evaluate whether a third-party HMI platform with broader multi-vendor protocol support would reduce integration complexity.
