Siemens SIMATIC AX WinCC Unified Elements Brings IT-Style Engineering to PLC and HMI Development
With the global PLC market surging toward an estimated USD 25.26 billion by 2034 and manufacturers facing a critical engineering talent shortage , as many as 1.9 million unfilled positions projected by 2033 in the US alone , the industry urgently needs tools that make automation engineering faster, more accessible, and aligned with modern software practices. Siemens' latest launch directly confron
Detail
Siemens' move to extend SIMATIC AX into HMI engineering represents more than a feature release , it signals a structural shift in how industrial automation projects will be built, reviewed, and maintained. By bringing visualization engineering into the same VS Code, based, Git-enabled environment that handles PLC logic, Siemens is effectively unifying the entire control system development lifecycle under one IT-aligned toolchain.
Announced on July 28, 2026, and available immediately in the United States, SIMATIC AX WinCC Unified Elements is a new engineering application that extends Siemens' SIMATIC AX platform into the realm of HMI and visualization. Previously, the SIMATIC AX family focused exclusively on PLC programming , leaving engineers dependent on TIA Portal for screen design and HMI configuration.
That gap has now closed. SIMATIC AX WinCC Unified Elements gives automation engineers a single, unified, IT-style environment where both control logic and its operator interfaces can be developed side by side, using the same workflows that IT software developers have relied on for years.
One of the defining features of the new tool is its dual-mode design approach. Engineers can build HMI screens in two distinct ways within the same AX Code environment , which is itself built on Microsoft Visual Studio Code, already familiar to millions of developers worldwide.
For engineers accustomed to traditional HMI development, the tool offers a graphical interface reminiscent of TIA Portal's familiar screen-building approach. Drag, configure, and deploy , all within the modern AX Code shell.
Every screen, faceplate, and HMI element can be defined entirely in human-readable YAML files. This unlocks capabilities that were never possible with traditional binary project files: diff comparisons between versions, pull request reviews, AI-assisted code generation, and full integration into CI/CD pipelines.
The convergence of IT and OT , a cornerstone of Industry 4.0 , is accelerating. Tools like SIMATIC AX WinCC Unified Elements that bring Git-based version control, modular reusable libraries, and text-based project definitions to factory-floor engineering are no longer experimental. They are becoming the baseline expectation for competitive manufacturing operations.
