Since HART technology has been around for many years, most people feel that they know all that there is to know about it. The fact is the vast majority of HART applications utilize only a fraction of the full capability of HART.
Batch material transfer control seems an easy task to carry out, but the reality is that many functions are necessary if the system is to accomplish accurate batch material transfer control. Weighing systems with device-level controls can help.
There's a myth in plants that HART offers little for Plant Control Systems and Enterprise Level Networks. But Ed Ladd from the HART Communication Foundation writes that by accessing the data in HART devices on a "full-time" routine basis increases performance, integrity, and reliability of plant control and enterprise level systems.
