IEC 61400-25-6:2016 specifies the information models related to condition monitoring for wind power plants and the information exchange of data values related to these models. This standard is to be used with other standards of the IEC 61400-25 series. This new edition includes the following significant technical changes with respect to the previous edition: – major restructuring of the data model to accommodate flexibility; removal of UFF58 format; – access to data using the standard reporting and logging functions; – recommendations for creating data names to accommodate flexibility
