ADR
The ADR range is a single byte which contains the address of the slave node (e.g. inverter).
The individual bits in the address byte are addressed as follows:
7
6 5 4 3 2
1
0
Special
telegram
Broadcast
bit
Mirror
telegram
5 Address bits
● Bit 5 is the broadcast bit.
Note
The Broadcast function is not supported in the current software version.
● Bit 6 = 1 indicates a mirror telegram.
The node address is evaluated and the addressed slave returns the telegram to the
master unchanged.
Bit 5 = 0, bit 6 = 0 and bit 7 = 0 indicate normal data communication for devices. The node
address (bit 0 to bit 4) is evaluated.
BCC
BCC stands for Block Check Character. It is an exclusive OR checksum (XOR) over all
telegram bytes with the exception of the BCC itself.
