PCM600 communicates with the bay IEDs via an Ethernet connection. Theconnection allows to reading and writing all configuration data needed for properoperation from or to the IED. The IEDs have communication interfaces forprotocols and media used for station communication. IEC 61850 communicationfiles for a bay IED or a complete station can be exported from PCM600 to stationengineering tools for engineering of station communication between bay IEDs andstation IEDs.A PC with PCM600 can be connected to any 650 series IED within a station usingthe Ethernet connection.The Ethernet connection can then later also be used for service and maintenancepurposes. The connection is also used to handle disturbance records inCOMTRADE format from protection IEDs using the IEC 61850 file transfer.The IEDs of today are designed on the concept of the IEC 61850 standard. This ismainly given for the organization of functions represented by an equivalent logicalnode in the IEC 61850 standard. The mapping between the logical node data modelin the IED, following the structure and rules in part 7 of the IEC 61850 standard,and the function blocks in an IED configuration is given in the IEC 61850communication protocol manual.The concept is also used for DNP3 protocol. The signals used or delivered by afunction block are automatically generated and available for stationcommunication. This concept allows a very efficient cost saving signal engineering.The IEC 60870-5-103 protocol is engineered in Application Configuration tool andParameter Setting tool.The engineering of the used communication protocols is a separate task and anaddition to the engineering of protection and control functions.PCM600 can be used for different purposes throughout the IED life cycle. A set ofspecial tools is available for different applications.The applications can be organized in:• IED product engineering• IED communication engineering per protocol• IED system monitoring• IED product diagnosticThis manual is valid for PCM600 supporting the 650 series product.2.2 IED engineering processPCM600 is used for various tasks in the IED engineering process.
