protection relay does not occur if the protection relay contains the
factory default technical key.
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 protection
relay and PCM600. The technical key can be read from the protection relay and
updated to PCM600, or the PCM600 technical key can be written to the protection
relay. Alternatively, a user-defined technical key can be defined.
When writing a configuration to the protection relay, PCM600 checks for a mismatch
between the IED object and the physical IED technical key.

Reboot suggestion
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.
Change the technical key for an IED object in the
Object Properties
dialog box in PCM600.

IEC 61850 naming conventions to identify an IED
This section is only valid when the IEC 61850 standard is used for station bus
communication. The IEC 61850 naming conventions to identify an IED are only valid
when the IEC 61850 standard is used for station bus communication. According to the
IEC 61850-6, the SCL model allows two kinds of project designations in the object
properties: a technical key and a user-oriented textual designation.
