Hierarchical Browsing

About this task

If your OPC HDA Server supports hierarchical organization of your tags in a tree structure, then Historian will use the server's hierarchy when browsing an OPC HDA Collector in the Non-Web Administrator.

Procedure

  1. Browse your OPC HDA data source for new tags.
    From the Collector list, select the OPC HDA Collector you wish to browse. A hierarchical tree appears in the Browse Results window.
  2. To limit the displayed tags to only those that are not collected, from the Show Only list select Source Tags Not Collected.
  3. To limit the displayed tags to match a tag name or tag description, enter the value to match in the Source Tag Name or Description text boxes.
  4. Navigate to the node in the tree you want to browse, and then click Browse. The tags within the selected portion of the OPC UA DA tag hierarchy will be displayed.
    • To browse automatically, select the AutoBrowse checkbox. The available tags display in the Browse Results window whenever a node is selected in the tree.
    • The Show All Children option is not supported.
  5. Select the tag(s) you want to add to Historian, and click Add Selected Tags. Collected tags appear in black text in the tag list.
