Engineering Manual
Several projects can be created and managed by PCM600, but only one project can be
active at a time.
Regardless the protocol used in installation for each project, the IEC 61850 version
must be selected when adding the first IED to plant structure. After the initial
selection, all IEDs in plant structure use the selected version, either Edition 1 or
Edition 2. In case the IEC 61850 is not used for station bus, the default version can be
applied. By default, the IEC 61850 version of PCM600 is Edition 1. The protection
relay's IEC 61850 version is by default Edition 2.
With PCM600, it is possible to do various tasks.
• Open existing projects
• Import projects
• Create new projects
• Export projects
• Delete projects
• Rename projects
• Copy and paste projects
The extension of the exported project file is .pcmp. The files are only used for
exporting and importing projects between PCM600s.

Technical key

Both a physical IED and an IED object in PCM600 have a technical key. The technical
key in the protection relay 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.
The protection relay is delivered with a factory default technical key.
The validation of the technical keys between PCM600 and the
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
