Only Structured Text can be edited directly!
For the graphical languages you have to import the POU from PLCopenXML or the codesys native format.
See IScriptTextualObjectMarker, IScriptObjectWithTextualDeclaration, IScriptObjectWithTextualImplementation and IScriptTextDocument for the textual language and the methods importxml() and importnative() from IScriptObject2 and IScriptProject2 for the import. Find the Scripting object, for example withfind(), and use the method remove() to delete an object.
