Glossary of Terms

Symbols & Numeric

(n)-Layer

Any specific layer.

(n)-Protocol

Set of rules and formats (semantic and syntactic) which determines the

communication behavior of (N)-entities in the performance of (n)-functions.

(n)-Protocol Data Unit

Unit of data specified in an (n)-protocol and consisting of (n)-protocol-control-

information and possibly (n)-user-data.

Access Point

Communication access point to an IED. This may be a serial port, an Ethernet

connection, or a Client or server address dependent on the stack being used.

Each access point of an IED to a communication bus is uniquely identified. Each

server has only one logical access point.

Active master

Interface allowing communication with IEDs (Intelligent Electronic Devices) that

use any protocol. The interface works by standardizing attributes of all possible

functions, so that these can be mapped to functions used by the IED.

Application and Transport Profiles (A-Profile and T-Profile)

Set of protocols for a specific purpose.

Application Layer

Layer 7 in the OSI reference model. It is the OSI layer closest to the end user,

providing an interface between the Open Systems Interconnection environment

and the end user's application.

messages.
