6.4 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 will
work. Other protocols do not all support the many data types that IEC 61850
does, so the IEC 61850 data will be converted to an appropriate data type in the
other protocol. For example, in the case of Modbus, much of the IEC 61850 data
will be converted to 16-bit integer words.
