Section 1: Introduction
Introduction
HART technology uses DD to achieve interoperability between actuators and control systems
or hosts from various manufacturers. For HART devices, in addition to providing parameter
definitions and information required by the control system to communicate with the HART
device, the DD may also include methods.

Actuator Description
Emerson Process Management electric actuators with HART option are microprocessor-based,
interoperable, process controllers, communicating with other valve actuators and types of
sensors and process control equipment. In addition to the primary function of controlling
the position of the valve, the Emerson Process Management electric actuator, using HART
communications protocol, gives easy access to information critical to process control. You can
gain information from the principal component of the process, the control valve itself, by using
a personal computer or operator’s console within the control room.
Using a compatible HART configuration device, you can obtain information about the health of
the actuator and valve. You can also obtain parameter access information about the actuator.
You can set input and output configuration parameters and calibrate the actuator. Using the
HART protocol, information from the actuator can be readily integrated into control systems
and process control strategies.
