Functional Constraints

Each IEC 61850 Data Attribute has a Functional Constraint (FC), which shows

what the data is or how it is used. For example, Data Attributes with FC=ST are

status data. Data Attributes with FC=CO can be controlled.

The Data Attributes Functional Constraints can be seen in the IEC Mapping Tool

window, for example:

Note: the little icons provide information. DO is for Data Object. Within the DO,

there may be multiple levels of data. When we get down to the Data Attribute

level, the functional constraint of the Data Attribute is shown in the icon, e.g. CO

for Control, ST for Status Information, and CF for Configuration.
