Both a physical IED and an IED object in PCM600 have a technical key. The technical key in the IED and PCM600 must be the same, otherwise it is not possible to download a configuration.
Each IED in a PCM600 project must have a unique technical key. Therefore, it is not possible to set the same technical key for several IEDs in the same PCM600 project.
Note: The IED is delivered with a factory default technical key. The validation of the technical keys between PCM600 and the IED does not occur if the IED contains the factory default technical key.
Note: The technical key property in PCM600 corresponds to the IED name attribute in SCL files. Avoid changing the IED name attribute outside PCM600, because data in PCM600 may get lost when importing the SCL files.
The technical key must be the same for the communication between the IED and PCM600. The technical key can be read from the IED and updated to PCM600, or the PCM600 technical key can be written to the IED. Alternatively, a user-defined technical key can be defined.
When writing a configuration to the IED, PCM600 checks for a mismatch between the IED object and the physical IED technical key.
Note: Ensure that the IED object in PCM600 has the same IP address as the physical IED that is intended to be connected through the technical key concept.
Note: Change the technical key for an IED object in the Object Properties dialog box in PCM600.
