The technical key property in PCM600 corresponds to the IED nameattribute in SCL files. Avoid changing the IED name attribute outsidePCM600, because data in PCM600 may get lost when importing theSCL files.The technical key must be the same for the communication between the IED andPCM600. The technical key can be read from the IED and updated to PCM600, or thePCM600 technical key can be written to the IED. Alternatively, a user-definedtechnical key can be defined.When writing a configuration to the IED, PCM600 checks for a mismatch between theIED object and the physical IED technical key.GUID-EF8A07F6-C6D1-4AA8-BDAD-A5F29F33389A V1 ENFigure 23: Reboot suggestionEnsure that the IED object in PCM600 has the same IP address as thephysical IED that is intended to be connected through the technical keyconcept.Change the technical key for an IED object in the Object Propertiesdialog box in PCM600.4.8.1 IEC 61850 naming conventions to identify an IEDThe IEC 61850 naming conventions to identify an IED are only valid when the IEC61850 standard is used for station bus communication. According to the IEC 61850–6clause 8.4, the SCL model allows two kinds of project designations in the objectproperties: a technical key and a user-oriented textual designation.Technical key is used in engineering drawings and for signal identifications. This iscontained in the attribute name as an identification of each object. If the value is usedas a reference to an object, it is contained in an attribute name starting with a stringdenoting the reference target object type and ending with the string Name.
