The connection between the physical IED and PCM600 is established via an Ethernetlink on the front or rear port on the IED.2.1 Monitoring and control system structureThe monitoring and control system for electrical substations contains a number ofIEDs for various purposes.See PCM600 documentation for the recommended size of a project.Larger projects can be divided into several PCM600 projects.IEC08000101.vsdBay levelStation levelStationCommunicationStation busbayIED 1bayIED 2bayIED n-1bayIED nNCC-GW(station-IED2)PCM600(tool set)HSI(station-IED1)IEC08000101 V1 ENFigure 2: Principle structure of a monitoring and control system for a substationThe monitoring and control system can be divided into three main parts.• Bay level IEDs• Station communication• Station level IEDsAll three parts require specific engineering and configuration.The plant structure is used to identify each IED in its location within the substationorganization. Plant structure is a logical image of the substation and the bays within thesubstation. The organization structure for the IEDs may differ from the structure of theprimary equipment in the substation.Section 2 1MRS240044-IB AIED engineering process16 REF615REngineering Manual
