MX/QX HART Field Unit FCD LMENIM2340-00 – 1/14

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.
