5.5 IEC 61850 Detailed Specifications

The IEC 61850 Client driver supports MMS (ISO 9506-1 and ISO 9506-2)

communication profile.

Part 7-2 of the IEC 61850 protocol specification lists the basic communication

structure and abstract communication service interface (ACSI). This IEC 61850

Client driver supports the following 7-2 models:

 Association

 Data Set

 Report Control Block (Data is updated based upon various trigger options)

 GOOSE (Data is updated based upon data change only. GOOSE message is

subscribed to.)

 Control

 Time and time-synchronization

 Naming conventions

Part 8.1: MMS later in this document lists the data types supported by IEC

61850. This is important for understanding how data mapping in the gateway

works. Other protocols do not all support the many data types that IEC 61850

does, so the IEC 61850 data is converted to an appropriate data type in the other

protocol.

5.5.1 Application Association Model

This section describes the gateway’s implementation of IEC 61850-72- Clause 7:

Application association model. This clause describes how the association

between two devices is achieved: TWO-PARTY-APPLICATION-ASSOCIATION

and/or MULTICAST-APPLICATION-ASSOCIATION. Both types are used.

Two Party Messaging

Two Party messaging is the most common type of messaging our IEC 61850

driver performs. The following diagrams show the execution of two-party

messages, and their associated abort sequence. In the diagrams, the IEC 61850

Client driver is the Client. This information has been taken directly from the IEC

61850 standard.
