Data Collection

Create data collection item

Create a new data collection item on the object. The DCI type is selected by the type property in the request body (item for a single-value DCI or table for a table DCI, default item). The server assigns the DCI id and returns the full created definition. Enumeration properties accept either symbolic names or raw numeric codes.
