It depend what registry you want to read. You should check in device manuals first. For example if your value is 8byte like the Active energy then datatype must be int64 this mean you will read 4 registers like in your script. If you want to read 1 register then datatype can be int16. Bus_dataype is KNX DPT to which you will convert the value. The rest should be clear.
