Abstract

Recently the HART devices have been increasingly used in Japan. HART devices which are used more than 30 million units in the world have the overwhelming share compared to the other field protocols. However about 85％ of the devices transmit the process variable of 4―20mA only and the diagnostic and other information are not utilized effectively. This paper describes how to make maintenance work efficiency of field instruments by using the full potential of HART devices with case examples.
