* – The new value is applied after restart.

** – Broadcast slave ID 0 can be used to assign a new ID to the instrument with an
unknown ID. When addressing by ID 0 the device shall be the only Modbus instrument in
the network. The device will not respond to the Master command when addressed by ID 0.

*** – This value is dynamic and not kept in EEPROM after a restart.
