item

In the DDE or SuiteLink protocol, a item is a data value placeholder. DDE protocol uses a three-part naming convention to locate information between applications. In order for an application (such as InTouch HMI software) to retrieve data, it must know the name of the application, the topic, and the item. An example of an item is the name of a cell in an Excel spreadsheet. Another example of an item is an InTouch tag. See also Dynamic Data Exchange, SuiteLink, topic.
