This document specifies a part of the application, the application layer, and the presentation layer.

The application covers the

  • device model,

  • registry management,

  • connection management for streaming data,

  • diagnosis, and

  • error handling.

The application layer covers the structure of MOST messages consisting of

  • addressing,

  • function block identifiers,

  • instance identifiers,

  • function identifiers,

  • operation types, and

  • timing definitions.

The presentation layer covers the definition of data, basic data types and function classes.
