OK lets take next step !
You can create your CSV (comma separated value) file in any text editor, Notepad, Notepad++ or in excel name it to whatever…. but extension .csv *(you create this file outside of uSimmics, at least I do it this way)
Now save that csv-file in your project-folder (maybe Grok_prj folder, your project name), thats the folder where you have saved your schematic, Grok_Twin-T.sch
Now in uSimmics, edit your file based voltage source, right click, edit properties, browse and select your .csv file, apply and OK.
Now you should have a file-based voltage source up and running
