Link Item

The Link Item object can be created in the I/O Model panel and is used to display dynamic values from a specified Linked Item, selected from any of the Model panels. The Link Item will show the real-time value of the linked object in the Faceplate of the Object Properties panel and will also provide historical data for the linked object when added to History Displays, or if history calls are made on the Link Item. They can also be used as triggering links for other items in the I/O Model panel.
