DALI Loop vs DALI Line

 I’m working through a spec for a commercial job with DALI. In some places this refers to DALI Lines and in other places DALI Loops; are they the same thing or different?

Older documents and standards used the term “Loop”. In recent years, the term “Line” has become preferred. Both terms mean the same thing: the DALI wiring making up the control circuit.

These days if “Loop” is used, the cause is probably a cut and paste from an older document or specification.

Now, try and use the term “Line”, it seems to be the more common and preferred description.
