Automatic Address Detection Function

Automatic address detection refers to a function that stores the IDs (addresses) of the connected slave modules in the
EEPROM of the RJ51AW12AL.
Pressing the SET switch on the RJ51AW12AL enables this function and enables the RJ51AW12AL to detect and store IDs
(addresses) of connected slave modules.
The ID (address) information stored in the EEPROM is held even when the power is turned off. However, information about
unset IDs, 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
execute the automatic address detection.

Executing the automatic address detection

To execute the automatic address detection, use the SET switch or 'Automatic address detection command' (Y1).
Using the SET switch
1.
Check that all of the slave modules are operating normally.
2.
Keep pressing the SET switch on the RJ51AW12AL until the SET LED turns on.
At this time, 'Automatic address detection flag' (X14) turns on.
3.
When the SET LED flashes for a while and turns off, the ID (address) has been stored.
4.
When 'Automatic address detection flag' (X14) turns off, the automatic address detection is completed.
Using 'Automatic address detection command' (Y1)
1.
