* - The new value is applied after restart.
** - Broadcast slave ID 0 can be used to assign a new ID to device with unknown ID. When addressing by ID 0 the device shall be the
only Modbus instrument in the network. The device will not respond to Master command when addressed by ID 0.
*** - This value is dynamic and not kept in EEPROM after restart
