About the HART Protocol

The HART Protocol was developed in the mid-1980s by Rosemount Inc. for use with a range of smart measuring instruments. Originally proprietary, 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). The protocol remains open and free for all to use without royalties.

This section focuses on providing information that is relevant to the various aspects of the HART Protocol. We will discuss what it is, how it works, and the benefits of using the HART Protocol.
