How to return the short addresses set on DALI drivers

[khalil]

Hello 
I have LM5 with built in DALI, I did a mistake and the short addresses disappeared from LM, but addresses still assigned to the Lighting DALI Drivers.
Is there a way to return the short addresses with the same previous addressing because I did the mapping and used these addresses in the KNX installation.

any help will be appreciated.
