6.2.5 Mailbox Message: Get Live List
This command returns 127 bytes of information about the nodes on the network.
Every byte stands for one bus subscriber, and the position of the byte in the
response data assigns the address (0 to 126). The content assigns the Station
Type.
This command can be sent in all operation modes (that is, STOP, CLEAR, and
OPERATE); however, the module must be initialized properly.
