Sampled Values

Sampled Value Control Blocks can be generated via a button in the toolbar (a), or alternatively from the context menu in the data model tree under Sampled Values (b).

The assignment to a Logical Node can be selected in the dialog, as can a corresponding name.

If you select the Sampled Value block created in the tree (1), you can make Sampled Value-specific settings in the Properties and thus implement the link to one of the created DataSets (2), for example.

Light Edition (9-2-LE)

If you select an existing IED in the tree, you have the option of adding a finished configuration in accordance with IEC 61850-9-2-LE (Light Edition) using the button in the toolbar.

In the following dialog, you have the option of setting the standard configurable settings. The settings are validated. In the case of an invalid value, a note on the valid value range is displayed in the respective tooltip.

Confirm the dialog to add a complete configuration in accordance with IEC 61850-9-2-LE (Light Edition) to the current project. This contains a logical device preconfigured in accordance with the standard, a preconfigured data set and the required Sampled Values blocks.

If you want to remove the entire configuration again, you only need to delete the logical device.
