Modify technical key for protection relay REF 630
In 61850 substation configuration, i have two relay protection that configured with the same technical key. I tried to modify one of them but when i sent the new technical key to the relay, i received an error message from PCM600. To do this, do i need IET600 or is there a specific procedure? Help me please.

Hi.
You don't need IET600 for this. Could you please add the information on the error message? What was the actual message?
One reason for the problem could be that PCM600 don't allow the same Technical Key for two devices even for a brief time. For some devices PCM600 needs to have the correct Technical Key to change the Technical Key in the device, so momentarily PCM600 tries to set the Technical Key which is already used by some other device in PCM600 project. If this is the case, then the procedure is something like this:
1. Locate the 2 relays which have the same Technical Key in your PCM600 project.
2. For the relay where you don't want to change the Technical Key, change the Technical Key temporarily to something else in the Object Properties window.
3. Now change the other relay Technical Key with the "Set Technical Key..." tool in PCM600.
4. Restore the original Technical Key for the second device which you changed temporarily in step 2.
