I'm dealing with importing/exporting of XML and SCL files (source code) into/from my TIA Portal project. I tried to execute the following command in python script:

Siemens.Engineering.SW.ExternalSources.PlcExternalSourceComposition.CreateFromFile(System.String(<name>), System.String(<path>))

 but it's not working. Does anybody have any idea how to implement this?
