Hello Luca,
unless there are some specific conditions or modules you are trying to use and are not supported by mappIO it’s relatively easy to use mappIO for modifying hardware configurations.
If you haven’t already check out the help here B&R Online Help - mappIO
Also read through the Use cases section in the help and check out the mappServiceHighlights sample which you can find under your AS install folder > Samples and contains a mappIO implementation.
If you have additional questions please don’t hesitate to reach back out.
