I’ve followed the SDK examples Request Data and SetData with success. I would now like to specify which data within a definition to write to – the example SetData writes to the whole definition. I believe I need to do something with Tagged Data to accomplish this? Might someone be able to explain what this flag does in layman’s terms? What I’m trying to do is read the values of all the fuel tanks within the aircraft and then write to specific tanks. Any help or suggestions would be greatly appreciated – I’ve not progressed with any of my attempts this afternoon.
