  3. In the Set Technical Key dialog box, select the technical key to be used. There are three alternatives.
    • Use the technical key in the IED
    • Use the technical key defined for the IED object in PCM600
    • Set a user-defined technical key, which changes the technical key for both the physical IED and IED object in PCM600
  4. Click OK to confirm the selection.
    Note: It is not possible to set a user-defined name or select Technical key in IED if the value is already given to another IED object in the PCM600 project. An error message is displayed if this happens.
