WinCC Open Architecture V3.17 is now available!

Get ready for the future of security and archiving with SIMATIC WinCC Open Architecture V3.17 

We are pleased to announce that SIMATIC WinCC Open Architecture V3.17 is now available.
In our current age of digitalization, having the best possible security measures in place has become the most important topic for vendors and operators of SCADA systems. SIMATIC WinCC Open Architecture V3.17 has set a high focus on the topic with its new and improved features.

The new functionalities include:

Next Generation Archiver

The NGA is a new way of archiving that supports the time-series data optimized InfluxDB. It comes with a smaller footprint (87% less storage compared to RDB) and better performance in both reading and writing. The same data can be archived into a local as well as a centralized database. Events and alarms can be archived without RAIMA.

New licensing technology

With Wibu CodeMeter, customers can manage their licenses autonomously. It allows more flexibility in changing licensed software configurations. Licenses can be assigned to either software containers or hardware dongles. Locally, a new integrated service provides the user with an overview of all licenses currently assigned to the device.

Node-RED integration

Node-RED is a Node.js based workflow engine that lets the user create workflows in a visual editor. It provides many useful pre-programmed nodes, e.g. for data exchange. The graphical editor reduces engineering effort drastically.

ULC UX for mobile browser

Additional to the Mobile UI App, ULC UX can now be used on mobile devices without additional installations or file downloads. With new multitouch support, more efficient full screen mode and window handling, it is now better aligned with native UI functionality than before.

Qt WebEngine support

The WinCC OA WebView EWO’s built-in browser engine was switched from Qt WebKit to Qt WebEngine. Performance and enhanced feature range are now comparable to Chrome 68.

CTRL++ enhancements

In addition to the introduction of a new vector datatype, the implementation of functions is now stricter and more precise, with e.g. syntax checking at declaration. The System Log output has been improved; there is now e.g. an added warning when a function returns a different datatype than specified.

OPC UA enhancements

There are a lot of new OPC UA functions available now, such as: individually configurable server subscription parameters, access to remote datapoints via DIST connection, 10x faster communication with S7-1500 PLC or the ability to track changes made by authenticated users on client side.

Security enhancements

V3.17 received IEC 62443-4-2 certification. Additionally, new security measures have been implemented, such as automatically setting the highest security level when creating a new standard project. The _auth config has been reworked for more flexibility. Panels and Scripts are now transferred and stored encrypted on remote Mobile & Desktop UIs.

QT V5.12 upgrade

The Qt version has been upgraded to V5.12, which enables the design of more exciting user interfaces, as well as better support for High-DPI displays.

General improvements and changes

In the PDF EWO a new function allows jumping to a defined anchor within the document. Among other things, the config file editor now has syntax highlighting. GEDI innovations include: files can now be directly saved into subprojects, columns in project view can be flexibly adjusted, GIT main functions available via right click context menu.


SIMATIC WinCC Open Architecture V3.17 is globally available from now on for Windows 10, Linux (RedHat 8.x, CentOS 8.x, SLES) and Siemens Industrial OS 2.0 (at release) as well as VMware including ESXi.
