Several major vendors have now announced plans to fully support enhancements to the electronic device description language (EDDL) used by HART devices, reports Ed Ladd of the HART Communication Foundation. These enhancements will allow users to interact with their intelligent devices in new ways. They ease configuration, even of complex instruments, and support storage of historical data for troubleshooting and diagnostics.
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.
