HART survey confirms technology’s long-term growth

The HART Communication Foundation (HCF) reports that a recent survey has confirmed that industry users and suppliers are firmly committed to the growth of HART Communication technology for years to come. Sponsored by HCF, the market survey was conducted by ARC Advisory Group (ARC), which investigated communication protocol plans of global users working in knowledgeable positions across the automation industry. The study reportedly verified continued use and increasing adoption of HART-enabled control systems and instrumentation.

For example, more than three-quarters of they survey’s respondents consider the HART protocol important when selecting products. Nearly 70% expect to maintain or increase their HART investments during the next 12 months.

In addition, a majority of respondents believe HART will continue to be important as they evaluate process instrumentation during the next five years. The survey also found that the largest growth for HART devices will be in final control elements and HART-enabled DCS/PLC systems. This translates to increasing demand for HART support and training from DCS, PLC, and control valve suppliers.

“The survey clearly shows continued market support for existing communication technology, which bodes well for the future longevity of HART,” says Wil Chin, ARC’s field systems director. “This should be a clear signal to suppliers to expand HART solutions to match users’ needs.”

Chin recommends that suppliers enhance their products, increase their knowledge base, and educate users on the benefits in their HART-enabled devices. He further suggests that users investigate the hidden benefits of HART technology, and determine how HART can improve the productivity of their plant. Chin also notes that both suppliers and users can benefit from becoming HCF members.

“HCF membership is open to anyone interested in using HART technology,” says Ron Helson, HCF’s executive director. “HCF members have access to all HCF resources, technical information, and programs to expand their knowledge and maximize HART smart instrumen-tation investments.”
