IEC 61850 data model, but all other aspects of the IED will remain unchanged
(e.g., names on the local HMI and names in the tools). This offers significant
flexibility to adapt the IED to the customers' system and standard solution.
The following tables list all the functions available in the IED.
Those functions that are not exposed to the user or do not need to
be configured are not described in this manual.
