Editing an Object Model

You can edit existing object models either from an online IEC61850 device or through the offline method.

Edit an Object Model from an Online IEC61850 Device
  • System Browser is in the Management View.
  • An IEC61850 device is connected to your system.
  1. In the System Browser, select the IEC61850 network and thereafter select the Device Connection object.
  • The details of the selected object such as name, description, IP address, and TCP port display in the Device Connection expander in the IEC61850 tab.
  1. Expand the Browse expander.
  1. Navigate to IEC61850 libraries and drag the object model to the Selected Properties section in the Browse expander.
  • The properties of the selected object model display in the Selected properties section.
  1. In the IEC Objects section, click Discover elements.
  • The information of the IEC61850 device objects and their associated properties displays in a tree structure in the IEC objects list.
  1. To add a new property, do the following:
  • Drag the leaf node associated with the required property to the appropriate folder in the Selected Properties section.
  • Specify a name and direction for the newly added property and click Update object model.
  • The property is added to the selected object model.
  1. To delete an existing property, navigate to the property and click .
  • The property is removed from the object model.

NOTE 1:
When updating the object model ensure that the newly added property must be of the same device.
NOTE 2:
For a new property that is added to the existing Object Model, the address is not automatically assigned. You have to re-import the CSV of the existing device to reflect the address configuration.

Edit an Object Model using the Offline Method
  • System Browser is in the Management View.
  1. Navigate to Project > Field Networks and select the IEC61850 network.
  • The Object Configurator tab displays.
  1. Click the Object Model Creator tab.
  1. Navigate to IEC61850 libraries and drag the object model to the Selected properties section in the Object Model Creator tab.
  • The properties of the selected object model display in the Selected properties section.
  1. Verify that all the data of the object model such as property name, description, IEC attribute, and type displays correctly for all the properties of the object model.
  1. To add a new property, do the following:
  • Click the Browse button and specify the path of the Substation Configuration Language (SCL) file. The SCL file can have either of the following extensions, .cid, .icd, .iid, or .scd. All the devices present in the SCL file are loaded in the IEC objects section.
  • Select a device and click Load elements. The properties of the device are loaded.
  • Drag the leaf node associated with the required property to the appropriate folder in the Selected Properties section.
  • Specify a name and direction for the newly added property and click Update object model.
  • The property is added to the selected object model.
