When IED configurations are changed using IET600. some preparations are

required when a project is started and the 615 series IED data model is imported to

the tool for the first time.

• The default 615 series IED SCL export from PCM600 contains five default

client definitions, “Client1”…”Client5”, which are used by all the RCBs.

MicroSCADA and COM600 clients can use the client definitions directly. If

other clients need to be added to the IET600 project, import the ICD file

describing the client data model to the project and attach the file to the same

IEC 61850 subnetwork in the Communication tab.

• Create the bus connections for the IEC 61850 clients.

All data sets must be configured under the logical node LLN0 and must be

provided with names unique within the IED. In 615 series IEDs there are a

maximum of four GOOSE control blocks allowed, which effectively limits the

relay to four data sets for GOOSE as there is a one-to-one correspondence between

the GOOSE control blocks and GOOSE data sets. Typically it is sufficient to

define a single data set and control block for an application. However, it is

recommended to use a separate data set and corresponding control block for analog values.
