ABB IEC 61850 Edition 2 Communication Protocol Manual

Also see for IEC 61850 Edition 2: Communication protocol manual

Detailed information regarding the IEC 61850 implementation of the IED isdescribed inside the conformance documents.• MICS, Modeling Information Conformance Statement, contains thedeclaration of the used logical node types.• PICS, Protocol Information Conformance Statement, contains the details andwhat is supported regarding protocol facilities.• PIXIT, Protocol Extra Information, contains additional information on how theIEC 61850 is implemented and used.• TICS, Tissue Information Conformance Statement, contains the supportedTissues, which are handled in the Tissues process as defined by UCA, UtilityCommunication Architecture forum. The Tissues handling is found in http://www.tissue.iec61850.com.The conformance documents are unique for each product release and refer to eachother. The identities included in the related documents refer to a specific version ofthe IED series.The communication profile in IEC 61850 uses the MMS standard, which usesEthernet and TCP/IP to handle the information transport within the substation.The data modelling uses the concept of logical nodes to identify the publishedinformation for communication. The standard defines a set of logical nodes, eachrepresenting a communication view of a process function with a number of dataobjects. For example, a transformer differential - or line differential protection,because the standard defines only a differential protection. Therefore, it is possibleto adapt the logical node, which is defined in the standard, as a logical node class.The standard defines methods to describe the actually used logical node as a logicalnode type which is then based upon the logical node class. This allows all partnersto interpret the logical node type information because the description is completelygiven in the standard. The type description of all logical nodes is part of the DataType Template (DTT) section in the SCL description file of a station or the IED.Besides the information about the configuration of the communication facilities,this manual contains the full description of all logical nodes available in the IEDs.The information about the logical nodes and their data objects may be used toidentify which signals are available for the functions as described in the technicalmanual. The link to the technical manual is done in the logical node tables bylisting the signal name as given in the function block, or as seen in PCM600 or theLHMI.2.1.1 Related documentation to IEC 61850 GUID-906D4C7F-29FD-4922-8A8B-8A3A3E2B811E v6Use the latest revision of the documents listed, unless stated otherwise.Section 2 1MRK 511 393-UEN AIntroduction to IEC 6185020 670 series 2.2 IECCommunication protocol manual
