The DALI protocol was first drafted in the late 1990s and has undergone a number of revisions as it has evolved. The result is version 2 of the DALI standard IEC 62386, which is known as DALI-2.

DALI-2 helps fill the gaps in the original standard, resulting in significant improvements in interoperability. DALI-2 adds new features and commands, and introduces standardisation of control devices for the first time, while maintaining backwards compatibility.

This Technical Note describes the necessary changes in Parts 101 and 102 to ensure there would be a clean split between system requirements in Part 101 and control-gear requirements in Part 102. Also, the Note covers the key features of the new Part 103, which defines general requirements for control devices.
