Connectivity and Communication of IEC61850 Devices with the IEC61850 Driver

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.

Re-import IEC61850 Objects in Logical and User Defined Views

When re-importing IEC61850 data in Logical and User Defined Views using a CSV file, the re-import applies only to the IEC61850 logical devices referred to in the CSV file.

The re-import operation is done in a similar way as the import, except that the existing IEC61850 logical device objects are updated as follows:

The new logical device entries in the CSV file are added to the existing logical device entries in the System Browser, if the Delete unselected items from the views check box is not selected.
If the device description of a logical device is modified in the CSV file, with no change to the existing paths of LogicalHierarchy or UserDefinedHierarchy, then the existing device description of the logical device is updated with the new description, if the Delete unselected items from the views check box is not selected.
If the device name or device description of a logical device is modified in the CSV file, with no change to the existing LogicalHierarchy or UserDefinedHierarchy paths, then the modified device nodes are added as siblings of the existing logical device nodes in the System Browser, as long as the Delete unselected items from the views check box is not selected.
If the device name or device description of a logical device is modified in the CSV file, with no change to the existing paths LogicalHierarchy or UserDefinedHierarchy paths, andthe Delete unselected items from the views check box is selected, then the existing logical device nodes below the hierarchy path are deleted and the device nodes in the CSV file are added. In this case, only the logical device nodes are deleted; the hierarchy paths are not deleted.
If the device name or device description of a logical device is modified in the CSV file, the existing path of LogicalHierarchy or UserDefinedHierarchy is modified, and the Delete unselected items from the views check box is selected, then the existing device nodes below the previous hierarchy path are deleted and the device nodes with new hierarchy paths in the CSV are added. In this case, only the logical device nodes are deleted; the hierarchy paths are not deleted.
If the existing LogicalHierarchy or UserDefinedHierarchy path is modified in the CSV file, the Delete unselected items from the views check box is selected, and there no change to the device name or device description, then the existing device nodes below the previous hierarchy path remains unchanged and the device nodes with new hierarchy paths in the CSV are added.
A logical device, for example, IEC61850 device1 associated with Device Connection IEC61850 Device Connection 1 is present in the logical view. On re-import, if there is no change to the name of the logical device entry in the CSV file, but the name of the Device Connection changes to IEC61850 Device Connection 3. In this case, #1 will be appended to the logical device name of the second entry in a logical view or user defined view. On subsequent re-imports, the number equivalent to #n+1 is appended to the logical device name.

In situations where there are two device nodes with the same names, the Importer performs the parsing operation using any of the following methods:

If a node with the same name does not exist, then the node is created.
If a node with the same name referring to the same data point exists, then only the description is updated.
If a node with the same name referring to a different data point exists, then a new node with name_#n is created.

Re-import IEC61850 Objects in Management View

When re-importing IEC61850 data using a CSV file, the re-import applies to the IEC61850 device connections and logical devices referred to in the CSV file. The re-import operation is done in a similar way as the import, except that the pre-existing IEC61850 objects are updated as follows:

Creating new device connections and logical devices.
Updating existing device connections and logical devices.
Deleting existing device connections and logical devices (only if the Delete unselected items from the Views check box is selected). Deleting the IEC61850 device connections and logical devices results in deleting them from all the hierarchies in other views.

This operation also causes the Management View hierarchy to update with any new objects that are added or removed from the CSV file.

The import process deletes any IEC61850 device connections and logical devices that are no longer present in the CSV file (only if the Delete unselected items from the views check box is selected).

During re-import, the IEC Importer prevents changing an already imported IEC logical device in the Object Model (OM) instance. For example, during import, if an instance of an IEC_Device Object Model is created with the name IEC_Device_1, then the Importer will report an error if you specify an instance with the same name (IEC_Device_1). but with a different Object Model during re-import.

Re-Importing Alias Information

The following information with respect to re-importing the data from the Alias column of the CSV file applies when re-importing objects from any of the views (physical, logical, user-defined).

If the alias information in the IEC61850 CSV file is not assigned to any node in the system, then the alias can be assigned to the IEC61850 Device Instance node or IEC61850 Logical Device node.
If the alias information in the IEC61850 CSV file is assigned to any node in the system, then the system checks to see if the name of the node to which the alias is assigned and the name of the node associated with the IEC61850 Device Instance or IEC61850 Logical Device are identical or different. If both nodes have identical names, then the alias information is imported. However, if the names of both the nodes are different, then the alias information is not imported since the same alias cannot be assigned to two nodes in the system. In this situation, a message informing you the reason for the import failure displays in the Preimport Log File dialog box.

Monitor IEC61850 Objects in the System

The management station monitors the number of IEC61850 objects in the system to ensure that the total count of these objects does not exceed the defined limits for the total number of system objects. The monitoring is done using properties such as System Objects Limit, System Load, System Objects, and Notification Threshold. These properties display in the Extended Operations tab when you select the Main Server Object from the Management View. Depending on the situation, the management station will perform any of the following:

Issue warnings when you are approaching the maximum permitted limit.
Generate an alarm if the System objects exceed the maximum permitted limit.
Prevent importing IEC61850 objects if the import activity can cause the system objects to exceed the maximum permitted limit.

The maximum permitted limit is defined by the System Objects Limit property.

The following scenarios provide a better understanding of the monitoring activity:

If the number of IEC61850 objects is below both the system limits (defined by the System Objects Limit property) and the safety threshold (defined by the Notification Threshold property), then the System Load property indicates Normal and displays in the Extended Operation tab only.
NOTE: If you want to import IEC61850 device connections or logical devices, the system will permit an import only if the System Objects Limit property and Notification Threshold property do not exceed their defined limits.

If the number of IEC61850 objects is between the system limits (defined by the System Objects Limit property) and the safety threshold (defined by the Notification Threshold property), then the System Load property indicates Warning and displays in the Extended Operation tab.
NOTE: In case of an import operation that exceeds the safety threshold, a warning message informs you how close you are to the limit (for example, 90%) and you can then decide whether or not to proceed with the import.
If the number of IEC61850 objects exceeds the system limits (defined by the System Objects Limit property), then the System Load property indicates Alarm and displays in the Extended Operation tab.
NOTE: If an import operation exceeds the system limits, an error message displays to inform you that the import will not start.

Upgrade of IEC61850 Connection Object Model

With Desigo CC V5.1, the IEC61850 connection objectmodel, 'GMS_IEC61850_Connection', which uses the internal DPT '_IEC61850_IED' provided by WinCCOA Platform is replaced with a new objectmodel 'GMS_IEC61850_Connection_1' which is an exact replica of '_IEC61850_IED'. The instances of GMS_IEC61850_Connection created in projects till V5.0 will be upgraded automatically to 'GMS_IEC61850_Connection_1' in V5.1 and later versions without any user intervention.

The object model upgrade process is triggered automatically when you upgrade your project to V5.1 and start the project for the first time in SMC. The upgrade process is triggered only when the drivers monitoring the old IEC61850 connection instances are in either the 'Started' or 'Configuration' states. If the drivers are not in either of the states, the system will monitor the driver's state after periodic time intervals.

If the upgrade process fails due to certain reasons, there will be two or more retries to upgrade the failed instances. The logs related to success and failure will be logged in a file located at <ProjectFolder>/log/IECConnectionOMUpgrade_Log_<TimeStampValue>.

If the upgrade process is not triggered automatically or fails at some point after multiple retries, then in order to trigger the upgrade process again, you must restart the project with a valid IEC61850 license and all the IEC drivers must be in either the 'Started' or 'Configuration' states. You can identify a failure in the upgrade process or a failure to trigger the upgrade process when you observe a loss of communication with field devices and thereafter checking the log file for such instances.
