It defines the protocol provided to define the wire-representation of the service primitives defined in IEC 61158-5-18:2010, and the externally visible behavior associated with their transfer. This second edition cancels and replaces the first edition published in 2007 and constitutes a technical revision. The main changes with respect to the previous edition are:
