Automatic Address Detection Function

Automatic address detection is a function to store the IDs (addresses) of the connected slave modules in the EEPROM
of the master module.
The parameters of the connected devices are automatically updated after storage in EEPROM of the master module
followed by detection of IDs (addresses) not set and the same IDs (addresses).
The ID (address) information stored in the EEPROM is held even when the power is turned off. However, information
about unset IDs and the same IDs and the parameter information of each slave module are not held.
Whenever starting the system or changing the system configuration, set the correct addresses to all the slave modules
and perform the automatic address detection.
