Wildcard address there was only 0xAAAAAAAAAA00,0xAAAAAAAA AA05,0xAAAAAAAAAA09,0xAAAAAAAAAA21, this
4 wildcard addresses do not save other wildcard addresses again later, therefore the wildcard of electric energy meter is successfully resolved under above situation
The maximum value of the quantity of the wildcard address saved in the list of location is 4；Due to wildcard address from 0xAAAAAAAAAA00 to
0xAAAAAAAAAA99 mono- shares 100, if the response returned after issuing from 0xAAAAAAAAAA00 to 0xAAAAAAAAAA99
Frame can be parsed correctly, i.e. 100 wildcard addresses all receive response frame, and 100 response frames can be parsed correctly,
The wildcard address being then saved in the wildcard address list for being successfully resolved to electric energy meter is 100, i.e., is successfully resolved to electric energy meter
Wildcard address list in the quantity of wildcard address that saves be 100 after be not further added by, the thresholding of maximum value is 100, when
