Hart (R) Opens up “smart” options
Abstract
Outlines the development of the HART communications protocol for “smart” instruments. Describes how the performance of the standard analogue 4‐20mA current loop can be enhanced and that two‐way digital communications can be implemented. Examines digital integration and the HART Expressway system. Finishes by looking at a windows based product called PROLINK designed for the Micro Motion mass flow marketplace. Concludes that standardisation in the world of “smart” plant instrumentation has widened the instrumentation choice for engineers and opened the door to new network management options for plant operators.
