Overview of IEC61850 protocol

IEC61850 defines an architecture to meet the needs of electrical substation automation. It defines a data model and the communication services for the interaction with and between the elements of a substation such as feeders, breakers, protection devices, etc.

The following image shows the data source input window for the IEC61850 protocol:

In order to connect a IEC61850 device, you need to select the IEC61850 protocol and enter the following data source parameters:

Parameter

Description

SCD File

Choose a valid SCD file. It contains the connection details (IP address, server name, access point) and the data (logical nodes, data types, data points, …).

The SCD File must have a valid extension: *.xml, *.zip, *.tgz, *.tar.gz.

Server Name

Name of the Intelligent Electronic Devices (IED) must match to the SCD file.

Access point name

Name of the access point must match to the SCD file.

NOTE

  • The IED name within the SCD file must be set to “MindSphereClient” or to the serial number of the device.

  • Server Name and Access point must match with the data in the SCD file. It is necessary for a double check of the configuration.
