Overview

The DLMS/COSEM specification is fully described in the DLMS UA coloured books:

  • the Blue Book describes the COSEM meter object model and the object identification system
  • the Green book describes the architecture and protocols to transport the model
  • the Yellow book describes the conformance testing process

The books are available for all members of the DLMS UA free of charge. Excerpts of the books are publicly available.
