2013 CONTROL READERS' SURVEY RESULTS

Usage of Field Network Protocols

Within the installed base of process instrumentation, "analog only" field instruments remain the most common and are in use at the facilities of 83% of respondents to a recent survey of Control readers. Further, among those with analog-only instruments in use, these devices account for a median 40-60% of the installed base. Among "smart" instrument protocols, HART Communication is used by nearly as many survey respondents (72%). Other digital protocols, such as Foundation and Profibus-PA, are used at fewer plants and typically to connect with smaller numbers of instruments. (See figures.)
