REX640 IEC 61850 Engineering Guide

From the IEC 61850 point of view, functional constraints should match between the ABB model and the FPN model. It is possible to map data between known predefined functional constraints. For example, different devices may have different requirements of setting group handling. When the FPN model is used for monitoring, a warning message can be ignored.

REX640 does not support substitution. It is, however, possible to have substation data in the FPN data model and map it to the REX640 application data.
