Siemens 6AV2124-0UC02-0AX1 SIMATIC HMI TP1900 Comfort 19-inch touchscreen panel for industrial automation operator stations

Siemens 6AV2124-0UC02-0AX1 SIMATIC HMI TP1900 Comfort Panel: Specifications, Alternatives, and Procurement Guide

Controls engineers evaluating a 19-inch HMI panel for a mid-scale automation project are typically choosing between committing to this catalog number, stepping up to the TP2200, or questioning whether the 19-inch form factor is genuinely justified. The Siemens 6AV2124-0UC02-0AX1 — the SIMATIC HMI TP1900 Comfort — answers that question with a 1366x768 TFT widescreen display, dual industrial Ethernet ports, and native support for PROFINET, PROFIBUS DP, Modbus, OPC UA, and EtherNet/IP, all within a 483 mm x 337 mm aluminum housing running Windows Embedded Compact 2013. It is a fixed, panel-mount operator interface designed for real-time process visualization, alarm management, and recipe handling in discrete manufacturing, packaging, food and beverage, and pharmaceutical applications.

Who Should Buy the 6AV2124-0UC02-0AX1 — and Who Shouldn't

The SIMATIC HMI TP1900 Comfort is the right choice when all of the following are true for your project:

  • Your application specifies a 19-inch widescreen display (18.5-inch diagonal, 1366x768 resolution)
  • Your panel enclosure can accommodate 483 mm width x 337 mm height x 73.2 mm depth with vertical mounting clearance
  • A 24 VDC supply at 19.2–28.8 V is available with sufficient margin above 41 W typical active draw
  • Your TIA Portal environment is V14 SP1 HSP or higher (legacy WinCC flexible is not supported)
  • Your primary communication path is PROFINET, PROFIBUS DP, Industrial Ethernet, or one of the supported third-party protocols (EtherNet/IP, Modbus, OPC UA)
  • The installation environment is indoors, temperature-controlled, and within 0–45°C at vertical mounting

If your application needs a smaller footprint, the TP900 or TP700 variants are the correct choice. If you require a 22-inch display for a command center or multi-zone visualization, look at the TP2200. For washdown or corrosive environments, the stainless steel TP1900S is the appropriate variant. This model is not rated for Zone 1 hazardous areas or outdoor unprotected environments.

What the SIMATIC HMI TP1900 Comfort Actually Does in a Running System

The 6AV2124-0UC02-0AX1 is a standalone operator interface panel that sits between the machine operator and the PLC. It does not process machine logic — that stays on the S7-1200, S7-1500, or S7-300/400 controller. What it does is give operators a live visual window into that logic: real-time process values, alarm queues, trend graphs, recipe parameter sets, and batch logs, all on a 19-inch resistive touchscreen with 40 direct touch keys for manual override functions.

The display is analog-resistive rather than capacitive, which means it responds to any firm contact including gloved hands, but it also means it may require periodic recalibration in high-touch environments — an important operational consideration for pharmaceutical or food lines. The 18.5-inch diagonal TFT delivers 16.7 million colors at 1366x768 resolution, and the backlight is rated at 50,000 hours MTBF at 25°C with dimmable output from 0 to 100 percent.

Beyond basic process display, the TP1900 Comfort runs full WinCC Comfort features under TIA Portal V14 SP1 HSP or higher: alarm and event logging, trending with historical data, recipe and batch tracking, PDF report export, HTML browser display, media player, and IP camera feed integration. The 24 MB of user data memory constrains how large a project can be, and integrators working with dense graphics libraries should size their projects accordingly before committing to a single panel.

The panel runs on Windows Embedded Compact 2013, which reached extended support end-of-life in 2023. This is a cybersecurity consideration for projects on shared networks — detailed further in the FAQ section below.

Where the TP1900 Comfort Sits in a Typical Automation Architecture

The 6AV2124-0UC02-0AX1 is the operator-facing node at the field level of a control system, receiving data from and sending commands to the PLC layer above it. It does not replace a SCADA server but can act as a local supervisor display for a small cell or line.

  • Engineering workstation (TIA Portal V14 SP1 HSP or higher) downloads the HMI project to the TP1900 via USB or Ethernet
  • The TP1900 connects to the plant network or PLC via one or both of its two industrial Ethernet ports (PROFINET switch port or independent Ethernet port)
  • The PLC (S7-1200, S7-1500, S7-300/400, or third-party via EtherNet/IP or Modbus) exchanges process data with the TP1900 in real time
  • For legacy installations, RS 485 connects the TP1900 directly to PROFIBUS DP or serial Modbus devices
  • The operator interacts via the 19-inch touchscreen and 40 direct keys; alarms, recipes, and reports can be printed or exported to USB storage (up to 16 GB stick) or SD card (up to 2 GB)

Industries and Applications Where the 6AV2124-0UC02-0AX1 Gets Specified

Packaging machinery builders frequently specify the TP1900 Comfort as the main operator station for form-fill-seal or cartoning lines where operators need to manage product recipes, view reject counters, and respond to fault alarms — all requiring readable screen real estate that smaller panels cannot provide.

In food and beverage plants, the 19-inch format supports batch tracking applications with up to 500 text lists and 500 graphics lists per project, plus the recipe view and PDF report export functions that satisfy production record requirements. The aluminum housing fits standard IP54 or IP65 panel enclosures when front-face sealed correctly.

Pharmaceutical filling and sealing lines use the SIMATIC Logon role-based access control built into the Comfort Panel platform to enforce operator, supervisor, and maintenance access tiers — a standard requirement for 21 CFR Part 11 adjacent workflows, though full compliance requires additional system-level configuration beyond the panel itself.

Machine tool builders integrating SINUMERIK CNC systems use the TP1900 as the operator display in a multi-axis cell supervisor role, showing KPIs, alarms, and shift logs from three or four remote CNC tools through a single panel station.

Legacy PROFIBUS DP migration projects — upgrading aging panels from 2005-era installations while retaining communication to S7-300/400 systems — are a common deployment scenario because the TP1900 Comfort supports PROFIBUS DP natively, eliminating the need for a protocol gateway during a phased modernization.

Application Typical Deployment
Packaging line operator station TP1900 as primary HMI with recipe management and reject counter display, PROFINET to S7-1500
Food/pharma batch management Recipe view, batch log, PDF report export via USB; PROFIBUS DP or PROFINET to S7-300/400
SINUMERIK CNC multi-tool supervisor Single TP1900 displaying KPIs and alarms from 3–4 CNC machines via Industrial Ethernet
Legacy PROFIBUS DP migration Replace aging panel, retain PROFIBUS DP bus to S7-300/400; no gateway hardware required
OEM machine frame integration Panel-mount in 1.2–1.5 mm aluminum sheet enclosure; 24 VDC DIN-rail PSU in same cabinet
Water treatment or HVAC control TP1900 with OPC UA client connecting to building automation or third-party controllers

Expert Verdict: Honest Assessment for Procurement and Integration

The 6AV2124-0UC02-0AX1 earns its specification in mid-scale automation because it consolidates what would otherwise require a panel PC plus a gateway plus a networking switch into a single DIN-rail-friendly device with a proven software stack. The dual industrial Ethernet ports — one operating as a PROFINET switch and one as an independent Ethernet interface — allow the panel to display an IP camera feed while simultaneously maintaining a live PLC connection, a capability that smaller Comfort variants or lower-tier competitor panels cannot match without add-on hardware. The 40 direct touch keys are a genuine operational advantage in applications where operators need one-touch manual control without navigating screen menus. The comprehensive protocol support (PROFINET, PROFIBUS DP, MPI, EtherNet/IP, Modbus, OPC UA) is the single strongest argument for choosing this panel in mixed-protocol or legacy-integration environments.

Where this panel has real constraints: the analog-resistive touchscreen is less responsive than capacitive panels and requires recalibration over time in heavy-use environments. The 24 MB user data memory is a hard ceiling that catches engineers who build graphics-heavy projects without checking file sizes during development. The Windows Embedded Compact 2013 operating system reached extended support end-of-life in 2023, which is a legitimate cybersecurity consideration for installations on shared or internet-adjacent networks — for projects where a current OS is a firm requirement, the TP2000 series or a panel PC platform is the honest recommendation. Finally, this is an indoor, controlled-environment device; the aluminum housing does not substitute for a stainless steel enclosure in washdown or corrosive atmospheres.

On the procurement side, standard distributor lead times run 2–4 weeks from stock, with direct-from-manufacturer lead times of 4–6 weeks — plan accordingly if this panel is on the critical path for a project build. Volume orders of five or more units typically attract additional discount tiers. If you are also sourcing a 24 VDC DIN-rail PSU rated for at least 5 A output to properly power the 41 W nominal draw, LeadTime.ca can bundle both items. If this matches your system requirements, view current stock and pricing at LeadTime.ca.

Wiring and Installation: What to Verify Before You Mount It

  • Confirm the mounting cutout matches 465 x 319 mm in a panel sheet rated 1.2–1.5 mm aluminum or equivalent; allow a minimum 80 mm rear clearance for connector access and cable management
  • Supply must be stabilized 24 VDC within the 19.2–28.8 V range; use an industrial-grade DIN-rail PSU rated at minimum 5 A output — the 1.7 A nominal draw at 41 W requires this margin; no integrated circuit breaker is present, so an external industrial DC fused disconnect is mandatory upstream
  • For PROFINET connections, use shielded Cat5e minimum (Cat6 preferred) Ethernet cabling; for RS 485 / PROFIBUS DP, use shielded twisted-pair with 120-ohm termination resistors at the first and last device on the bus only
  • Assign a static IP address via TIA Portal V14 SP1 HSP or higher before first use, or configure DHCP; test PLC reachability with a ping before downloading the application project
  • Tilt mounting up to 35° is supported without forced cooling, but the maximum operating temperature drops from 45°C to 35°C — confirm ambient conditions in the installation enclosure before choosing a tilted orientation

Compatible PLCs, Controllers, and Communication Protocols

The 6AV2124-0UC02-0AX1 communicates natively with the following controllers and systems without requiring a protocol gateway:

  • S7-1200 and S7-1500 — via PROFINET or Industrial Ethernet; preferred path for new projects
  • S7-300 and S7-400 — via PROFIBUS DP, MPI, or Industrial Ethernet; primary use case for legacy migration projects
  • S7-200 — via MPI or point-to-point serial
  • LOGO! compact logic modules — direct communication supported
  • WinAC software PLC — supported within the Siemens ecosystem
  • SINUMERIK CNC systems — with option package enabled in TIA Portal
  • SIMOTION motion control — direct support within TIA Portal configuration
  • Allen-Bradley controllers — via native EtherNet/IP support; no external gateway required
  • Modicon and Modbus-compatible devices — via Modbus TCP over Ethernet or Modbus RTU over RS 485

What Engineers Get Wrong When Ordering This Part

Before submitting a purchase order for the 6AV2124-0UC02-0AX1, verify each of the following items verbatim against your project requirements:

  1. Verify exact catalog number 6AV2124-0UC02-0AX1 (not 0AX0 variant or TP2200 series)
  2. Confirm 19-inch form factor requirement (display diagonal 18.5 inches, resolution 1366x768)
  3. Check 24 VDC supply available; verify power margin above 41 W typical draw (external PSU required)
  4. Confirm TIA Portal version is V14 SP1 HSP or higher; legacy WinCC flexible not supported
  5. Validate primary communication interface available on target PLC (PROFINET/PROFIBUS DP most common)
  6. Ensure mounting space allows 483 mm width x 337 mm height x 73.2 mm depth
  7. Confirm vertical mounting is feasible (tilt angle operations reduce max temp to 35°C in portrait)
  8. Check Windows Embedded Compact 2013 compatibility with custom applications or third-party libraries

If any of these checks raise a flag, contact the LeadTime.ca team before ordering — we can confirm the correct catalog number or identify the appropriate alternative variant.

Frequently Asked Questions

Does the 6AV2124-0UC02-0AX1 work with TIA Portal V15 or V16, or only V14?

The minimum required version is TIA Portal V14 SP1 HSP. Later versions of TIA Portal (V15, V16, and higher) are backward compatible with TP1900 Comfort projects, so upgrading your engineering environment does not obsolete an existing 6AV2124-0UC02-0AX1 installation. Legacy WinCC flexible is not supported on this panel — if your existing project was built in WinCC flexible, it requires migration to WinCC Comfort before deploying on this hardware.

What is the realistic lead time for the 6AV2124-0UC02-0AX1, and should I order early?

Standard distributor stock in most markets carries a 2–4 week lead time. Orders placed directly through the manufacturer typically run 4–6 weeks, and bulk orders may extend further. For integration projects with a defined commissioning date, ordering with a 6–8 week buffer is strongly recommended to absorb supply chain variability. The TP1900 Comfort is not end-of-life as of 2026, and full support is expected for at least five additional years.

Can the TP1900 Comfort display an IP camera feed while connected to a PLC?

Yes. The dual industrial Ethernet architecture — one port operating as a PROFINET-capable switch port and one as an independent Ethernet interface — allows simultaneous PLC communication and IP camera display. This is one of the primary reasons integrators specify the TP1900 over smaller Comfort variants, which do not carry two independent Ethernet ports.

Is the Windows Embedded Compact 2013 OS a cybersecurity risk for my installation?

Windows Embedded Compact 2013 reached extended support end-of-life in 2023, meaning security patches from Microsoft are no longer routinely issued. For installations on air-gapped or dedicated industrial networks isolated from corporate IT and internet access, this is a manageable risk with proper network segmentation and VLAN architecture. For installations sharing Ethernet infrastructure with corporate networks or internet-connected systems, this is a legitimate concern — in those cases, plan to evaluate migration to a newer panel platform or implement strict firewall and VLAN controls at the network layer.

What external power supply specification is required for the 6AV2124-0UC02-0AX1?

The panel requires a stabilized 24 VDC supply within the range of 19.2–28.8 V, with nominal current draw of 1.7 A and active power consumption of 41 W. The inrush characteristic is rated at 0.5 A²·s. An industrial DIN-rail mounted PSU rated at minimum 5 A output (approximately 120 W capacity) provides an adequate safety margin. No circuit breaker is integrated in the panel — an external industrial DC fused disconnect or circuit breaker is required upstream.

What is the maximum project size the TP1900 Comfort can hold?

User data memory is 24 MB. This encompasses application graphics, alarm lists, text lists (up to 500 with 500 entries each), recipes, and log files. Dense graphical projects or those with large image libraries should be sized and tested in TIA Portal simulation mode before downloading to hardware to avoid memory-full errors at commissioning. External storage expansion is available via USB stick (up to 16 GB) and SD card (up to 2 GB) for archiving data files, but the 24 MB limit applies to the onboard project runtime.
