In today’s competitive landscape, all companies aim to reduce operation costs, deliver products rapidly, and improve product quality. The highway addressable remote transducer (HART) protocol directly contributes to these business goals by providing cost savings in:

• Commissioning and installation
• Plant operations and improved quality
• Maintenance

The HART Protocol was developed in the mid-1980s by Rosemount Inc, The protocol was soon published for free use by anyone, and in 1990 the HART User Group was formed. In 1993, the registered trademark and all rights in the protocol were transferred to the HART Communication Foundation (HCF).
