This part of IEC 61850, which is a Technical Report, describes the methodologies for themodelling of logics for IEC 61850 based applications in power utility automation. In particular,it describes the functional view of logic based on existing logical nodes for generic processautomation and the operational modes of the logic. Furthermore it includes the specification ofthe standard language to be applied to specific the logic as well as the related data exchangeformat between engineering tools and their application as well as the mapping of logic elementsto IEC 61850 data types.
