NOTE
The default address is 1.
The address 0 is reserved to identify a “broadcast” exchange (Master sends a
request to all Slaves connected to the Modbus network). See the “6.1 MODBUS
Master / Slaves protocol principle” section on page 50.
The Modbus Master node has no specific address, only the Slave nodes must
have an address. Each Slave must have a unique address.
Addresses from 248 to 255 are reserved.
If you set the address 0, device will be set to 1 automatically.
If you set an address that is greater than 247, the device will be set to 247
automatically.
The node address which is currently set in the unit can be read next to the
