Substitution function

Post by Nikolay » Fri Jun 26, 2020 9:42 am

Dear colleagues.
There is a function “substitution”, if the signal should not be registered in the system, it needs to set a certain fixed value and not process it in the system. We made this function like this: for a certain signal, we remove the Active property in para. But our signal processing is implemented in such a way that incoming signals are still trying to write to para (but due to Active = False this is impossible), which leads to a huge number of warnings in the log. How to implement this function?

I think you are looking for the config _default (Default value) .
this is chapter "Module PARA --> Data point configs --> _default" in the WinCC OA documentation
