This ability allows for implementations like day/night mode. Color schemes are sets of named colors that can be swapped into place on a system during runtime. One of those extra benefits that WinCC OA provides is the ability to use color schemes. These objects have behavior and visualization that is similar to the PLC Open Library while still extending the functionality to provide for the benefits of using WinCC OA. These can often be utilized by themselves as part of your project or embedded into your own custom objects! Look and Feel

There are plenty of helper objects, such as the text indicator and entry objects not listed here that are used by the objects above. This latest version has implemented the critical portions of the PLC Open Library with objects for: Several revisions later, we have an extensible code base covering the key elements of the PLC Open Library and are ready to share it with the world. This initial version was a great start for clarifying how to use the new WinCC OA Object-Oriented CTRL++ language that had just been released. This resulted in the alpha version of a WinCC OA Open library in July 2017. Rather than continually reinvent the wheel each project, we decided to distill best practices into a set of tools that integrate seamlessly into the Siemens PLC Open Library. It has incredibly powerful ways of creating reusable and self-configuring objects, but this is “an exercise left to the user,” as my old college professors would say.

WinCC OA is provided to users as a clean sheet. The Siemens WinCC OA Open Library Version 1.0 is now live, and the website is up to date with the latest version and release notes.
