WinAC RTX relies on IntervalZero RTX or proprietary Siemens real-time extensions. During installation, the software modifies the boot configuration to allocate specific CPU cores exclusively to the real-time PLC task, isolating it from standard Windows processes. Step-by-Step Installation Guide
For a comprehensive understanding of the system, refer to these core manuals provided by Siemens:
While the is excellent for existing installations, Siemens is pushing users toward newer architectures for greenfield projects:
Unlike WinAC RTX, which relied on the IntervalZero RTX real-time core within Windows, the S7-1500 Software Controller operates autonomously and independently of Windows. TIA Portal Integration: Modern PC-based control is managed through the TIA Portal simatic winac rtx download new
Before downloading, ensure your PC meets the necessary requirements:
On the results page, look for your product entry. Click on the tab. Do not click on "Documentation" (that includes manuals) or "CAx data".
This is why, despite what some outdated third-party websites might suggest, you cannot find a legitimate, trial, or demo version of WinAC RTX for free download. Siemens offers no public download link for the software itself. However, if you have a valid license, you can still access the software to maintain your existing automation systems. WinAC RTX relies on IntervalZero RTX or proprietary
To obtain the software, legitimate users with a valid license must directly request it from Siemens Technical Support, providing their article number. This process is in place to ensure that only licensed users can access and maintain their existing automation systems. While WinAC RTX remains a highly capable and stable Soft PLC, it's essential to plan for the future, with the S7-1500 Software Controller being the recommended path for new developments.

: If you're unable to find what you're looking for online, consider contacting Siemens support directly. They can provide guidance on the latest software versions, compatibility, and downloads.
Right-click the setup file and select "Run as Administrator." Follow the prompts to install both the WinAC controller software and the bundled RTX runtime.
While you can still download SIMATIC WinAC RTX updates and service packs from the Siemens Industry Online Support portal to maintain legacy hardware, the era of "new" WinAC deployments has ended. For existing systems, ensure you run WinAC RTX 2010 SP3 with the latest security updates on validated industrial hardware. For any new engineering designs or system overhauls, pivot toward the SIMATIC S7-1500 Software Controller to secure long-term support, safety integration, and modern cybersecurity features.
