Available only in VTScada-based applications.
Data Flow RTU drivers are used to provide an interface to a Data Flow RTU. Each Data Flow RTU driver provides for up to 18 installed Data Flow modules, each of which is represented by a single Data Flow module tag (see Data Flow Module Tags).
Note: Data Flow RTU driver tags do not require polling drivers since they have their own polling features. Please refer to VTScada Tag Hierarchy for illustrated examples of the relationship between the tags in a Data Flow RTU based system and a non-Data Flow RTU based system, or refer to Polling Driver Tags for further information.
Operators who do not have configuration privileges, but do have either “tag modify” or “manual data” security privileges can toggle the active polling state on or off if this tag is drawn as a Comm Indicator on a page. When the operator right-clicks on the Comm Indicator for the driver, a context menu will open, allowing the Active status to be changed.
