7.2.7.2 Definitions of the ISO/OSI reference model
Communications are based on the OSI Reference Model (OSI/IEC 7498-1) for a multi-layer communication function, to
achieve stable data exchange.
The table below shows the ISO Application (A) and Transport (T) profiles.
•An ISO A profile is a set of specifications and declarations regarding the top three layers of the ISO/OSI reference
model (i.e. the application, presentation, and session layers).
•The T pr
ofile is a set of specifications and declarations regarding the lower four layers (i.e. transport, network, data
link, and physical layers).
Table 7-1: OSI reference model and profiles
A and T profiles can be combined in various ways to form different types of services and information items that can be
exchanged. The services specified in Part 7-2 of the IEC61850 standard are mapped onto four different combinations of
the profiles. These four combinations are used for
• Client/server services,
• GOOSE/GSE management services,
•GSSE services,
• Time synchronization,
• Services for measured value sampling.
