I've been exploring ways to automate HMI/GUI testing in WinCC OA. As part of this process I was looking for ways to externally set/get dpe values through external software to avoid manually editing values within the PARA while testing.
Note that I'm aware it is possible to externally set dpe values through the C# api see: https://www.winccoa.com/documentation/W ... PI-01.html
or in python through the third party tools such as oa4j:
https://github.com/vogler75/oa4j-wss
However those solutions seem limited to Windows only while my WinCC OA installation is on linux, so I was hoping if anyone knew if there was some other out of the box solution to externally set/get dpe values externally on linux?
Or would my best option be to generate a custom driver for this sort of thing?

You could try the direct get and set mode of the ASCII manager.

WINCCOA 3.19 C# API Can running on Linux
Re: Interacting with dpe values with an external api on linux
According to the information in the WinCC OA Documentation for 3.19 the C# API is not supported on Linux systems.

Re: Interacting with dpe values with an external api on linux
I think you are referring to this possibly outdated information. Since all information mention that the new C# API is platform independent and even you yourself referred to this in reply to the question if there are plans to support the C# API on linux
