7.1
IEC 61850 protocol references and pre-conditions
To engineer the IEC 61850 protocol interface for the protection relay, the following
additional manuals or knowledge of their contents is required.
•
Knowledge of the IEC 61850 engineering process as described in the IEC 61850
standard
•
The technical manual describes the function blocks defined as logical nodes
•
The IEC 61850 engineering guide
•
The IEC 61850 conformance documents for the protection relay to be engineered
•
The IEC 61850 parameter list
