Creating Object Models for IEC61850 Devices

Scenario: You want to create object models for IEC61850 devices.

 

Reference: For background information, see the reference section.

 

Workflow diagram:

 

 

Prerequisites:

  • You have the software distribution containing IEC61850.
  • You have installed IEC61850 feature and have added it to a management station project using the SMC.

 

Steps:

1 – Create the Object Model
  • You can create the object models for the IEC61850 devices using any of the following methods:
2 – Configure Object Model for Event Support
  • You have created an Object Model with the Value.info.FaultNumber property and it displays in the respective Libraries folder. Along with the Value.info.FaultNumber property, additional properties such as Value.info.FaultAlarm, Value.info.LastProcFltNum, Value.info.Request, Value.info.Response, and Value.info.FaultFilePollInterval are also added to the object model.
  1. In System Browser, select Management View.
  1. Select System Settings > Libraries.
  1. Navigate to the Libraries where you created the object model and select the object model.
  1. Perform the following steps:
  • Select the Value.info.FaultAlarm property and in the Alarm Configuration section, select Field system and in the Alarm table reference, select Default.
  • Select the Value.info.Response property and configure a GenericWriteString command.
  • The object model is updated with additional properties to support Fault events.
3 – Configure Import Rules of an Object Model
  • You have added a library block for IEC61850.
  • You have set the Managed Type for the object model to IEC61850PredefinedDevice. The object model only becomes visible when you set the Managed Type.
  1. Select the Import Rules tab (See Import Rules Workspace in Librarian Configuration Workspace).
  1. Open the Objects and Properties expander.
  • All the objects contained in the imported object model become available.
  1. Select an existing object model.
  1. Specify the address profiles to be associated with the object model. You can create multiple profiles, however only one profile can be set as default.
  1. Configure the following parameters for each listed property of the selected object model:
    - Direction
    - Transformation Type
    - Reference
    - Active
    - Visibility:     Select the Visibility check box if you want the property of the selected object model to be displayed in the Operation and Extended Operation pane. By default this check box is selected, however, if you do not want to display this property, you must deselect this box.
    - Low Level Comparison: Low Level Comparison is applicable for only those properties with Direction as Input or InOut. By default, this check box is unchecked. If this box is selected, then the driver sends only the changed property values to the device.
  1. Click Save .

NOTE:
You cannot have empty values for the Import Rules of an object model in the Properties section.
