F Section 1 Introduction Section 1 Introduction This manual GUID-AB423A30-13C2-46AF-B7FE-A73BB425EB5F v20 The communication protocol manual describes the communication protocols supported by the IED. The manual concentrates on the vendor-specific implementations. Intended audience GUID-C9B8127F-5748-4BEA-9E4F-CC762FE28A3A v11 This manual is intended for the communication system engineer or system integrator responsible for pre-engineering and engineering the communication setup in a substation from an IED perspective.
Section 1 1MRK 511 415-UEN Rev. F Introduction The engineering manual contains instructions on how to engineer the IEDs using the various tools available within the PCM600 software. The manual provides instructions on how to set up a PCM600 project and insert IEDs to the project structure.

F Section 2 Introduction to IEC 61850 Section 2 Introduction to IEC 61850 Overview GUID-66925336-B6C3-4B22-95F4-A3321B63FABB v7 The general scope of the IEC 61850 protocol standard is designed to support the communication of all functions being performed in the substation. Its’ main goal is interoperability; this is the ability for IEDs from one or different manufacturers to exchange information and use the information for their own functions.
Section 2 1MRK 511 415-UEN Rev. F Introduction to IEC 61850 The data modelling uses the concept of logical nodes to identify the published information for communication. The standard defines a set of logical nodes, each representing a communication view of a process function with a number of data objects. For example, a transformer differential - or line differential protection, because the standard defines only a differential protection.

F Section 4 Communication profile Section 4 Communication profile GUID-25495333-A2B7-44A7-908D-68EC06694AD5 v7 The IEC 61850 standard is conceptually written to be independent of an existing communication media and message transmission concept. Out of this, a specific communication profile is decided and has been commonly used.

This configuration is done in ECT and there it is a column to fill in the SvCBRef. This field is used to identify what sampled value stream that is supervised and should, according to IEC 61850, be set to the IED and control block name of the sending IED.

F Section 7 Data sets and control blocks Section 7 Data sets and control blocks Data sets SEMOD129786-5 v10 IEC 61850 has defined data sets and report control blocks to transmit signals for monitoring purposes. Data sets are also used for GOOSE messages in horizontal communication among IEDs. The project defines the data objects or single data attributes that should be collected in a data set.
Section 7 1MRK 511 415-UEN Rev. F Data sets and control blocks • All data objects or their data attributes can be selected for a data set. • Only those data attributes of a data object can/will be selected which have the same function constraint (FC).
