WirelessHART: A Natural Progression in HART Protocol

摘要

The Highway Addressable Remote Transducer (HART) protocol is one of the most widely used industrial standards. Millions of devices around the world utilize the HART protocol for process-measurement applications. However, according to the HART Communications Foundation, as many as 90 percent of these devices are stranded, using only the 4 to 20 mA signal and leaving the HART data inaccessible. To help rescue stranded data from these inaccessible HART devices, the HART Communications Foundation introduced the WirelessHART protocol. This relatively new addition makes the popular HART protocol more usable, flexible and cost effective.
