Connectivity and Communication of IEC61850 Devices

The connectivity and communication between the IEC61850 devices and the IEC61850 Driver depends on the values of properties that are set for a Device Connection object. After successfully importing the IEC61850 CSV file, the Device Connection object is created and the default values of its properties display in the Extended Operation pane. For a successful communication between the IEC61850 devices and the IEC61850 Driver, you must ensure the following:

• The IEC61850 devices and IEC61850 Driver are connected if the properties such as, client AP Title and Server AP Title, Client PSEL and Server PSEL, Client SSEL and Server SSEL, and client TSEL and Server TSEL are identical and are set to their default values.
• If the value of the client or server version of a property (for example, Client AP Title or Server AP Title) changes to a value other than the default value, then the device is disconnected.
• The devices continue to be in the connected state if the value of the client or server version of the properties such as, Use Client Invoke Settings and Use Server Invoke Settings, and Use Client Title Qualifier Settings and Use Server Title Qualifier Settings are changed to a value other than the default value and are identical. For example, if the Use Client Invoke Settings property is set to Disabled, then the Use Server Invoke Settings must also be set to Disabled.
• You must compare the property values of the Device Connection object that are displayed in the Extended Operation pane with the property values in the Substation Configuration Language (SCL) file of the IEC61850 device. If the property values in the SCL file are different, then they must be updated from the Extended Operation pane.
