hex
= 8605
Bit 16 ... 39 (LBS) device Id Number (z) (Bit 16 = MSB, Bit 39 = LSB),
(corresponds to the address, results from an XOR link between identification number and
serial number of the device)
Each field device must reply to address 0 (bit 2 … 39 = 0) (broadcast telegram)

command 3.4.5.
Commands are divided into the following categories in conformity with HART:
Universal commands
Commands 0 ... 30
Standard commands Commands 32 ... 126 (123 ... 126 not public)
device-specific command Commands 128 ... 253
(reserved: 31, 127, 254, 255)
Byte count 3.4.6.
The byte count indicates how many more bytes come before the checksum, i.e. the number of status bytes +
number of data bytes. This results in a maximum total number of 255 status and data bytes.
