0x03/0x06object action code, 0x03 = set flag, 0x06 = clear flag
Individual flags are written by supplying the corresponding meter address.
The flags of all installed meters can be written (set or cleared) with a single command by setting all eight meter
address bytes to 0xFF.
Important note!
This command is useful only for changing lock flags of meters that are already installed in the meter list since a
meter's lock flag will always be cleared as default at the moment of installation.
6.3.30 Set configuration tag
The configuration tag can be used to indicate if changes have been made in the LCD menu after any
configuration has been made using the wired M-Bus interface.
