and protocols for COSEM clients and servers, and defines how to use the COSEM application
layer in various communication profiles.
It defines services for establishing and releasing application associations, and data
communication services for accessing the methods and attributes of COSEM interface
objects, defined in IEC 62056-62, using either logical name (LN) or short name (SN)
referencing.
