Introduction
1.1 Purpose
This manual explains how to install and operate the MX/QX HART field unit. Actuators containing the HART field unit
may be connected by a standard instrumentation twisted-pair cable to form a HART communication system network.
The HART network employs a bi-directional communication protocol, operating at 1200 bits/sec, that provides data
access between intelligent actuators and host control/monitoring systems. In addition to a digital signal, the network
simultaneously provides a 4-20 mA analog signal that is proportional to the field unit’s primary measured value. This
system allows a host system such as a distributed control system (DCS) to control and monitor the actuators, including
the acquisition of status and alarm data from each MX/QX.
