IEC 61400-25-6:2010(E) specifies the information models related to condition monitoring for wind power plants and the information exchange of data values related to these models. The purpose is to model condition monitoring information by using the information modelling approach as described in IEC 61400-25-1 and by extending the existing information model as specified in IEC 61400-25-2, the information exchange models specified in IEC 61400-25-3 and the mapping to communication profiles as specified in IEC 61400-25-4.
