4.3 Setting technical keyBoth a physical IED and an IED object in PCM600 have a technical key. The purposeof the technical key is to prevent download of a configuration to wrong IED. Thetechnical key in the IED and PCM600 must be the same, otherwise it is not possibleto download a configuration. Each IED in a PCM600 project must have a uniquetechnical key. It is therefor not possible to set the same technical key for several IEDsin the same PCM600 project.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 might be lost when importing SCLfiles.The IED technical key and the PCM600 technical key must be thesame for successful communication between the IED and PCM600.When using PCM600 for writing to the IED, it is important that theLHMI is not in a menu position where settings can be made. Only oneactive transaction, from LHMI or PCM600, is allowed at any onetime.When writing a configuration to the IED, PCM600 checks the mismatch between theIED object and the physical IED technical key, if any. For communication between theIED and PCM600 the technical key must be the same. Users have the option to readthe technical key from the IED and update it to PCM600 or write the PCM600technical key to the IED. The user can also define an own technical key.
