Use the OPC Item Browser

The OPC Item Browser allows you to browse the namespace of an OPC Server and choose items to add to a scan group, block read group, or block write group.

The browser has seven main components:

• Branches window- displays the logical groupings of items as configured in the application.

• Available Items window- displays all items associated with the grouping selected in the Branches window.

• Basket (Selected Items) window- displays those items that have been selected from the Available Items list for inclusion in a scan group, block read or block write group. To add items to the Basket, select one or more in the Available Items window (multi-select is allowed) and click Add (the plus sign). Alternatively, you can click-and-drag items to the Basket; select items and press Enter; or right-click the selected item(s) and click Add to Basket on the options menu. Duplicate items will not be added to the basket.

• OK button- closes the browser and adds items in the Basket window to the Associated attributes list in the object’s editor.

• Filter button- starts the Specify Filter Criteria dialog box, in which you can set filtering criteria that restricts the data shown in the Available Items window. See Specify Filter Criteria dialog box for more information.

• Cancel button -loses the browser and does not add items in the Basket window to the Associated attributes list in the object’s editor.

• Status bar- Based on the cursor location, it displays hint information such as which application you are browsing and the node it is located on, or what to do when items are selected in the Available Items window.

  Note: When you click OK, each item in the Basket window becomes a separate attribute in the object editor’s Associated attributes list. If a Basket item already exists in the Associated attributes list, it is not added again to the list and a message is displayed informing you that some item(s) in the Basket list were duplicates.

Note: When you close the browser with either the OK or Cancel button, the Basket window and all filter criteria is reset.
