Introduction
1.1 Purpose
This manual explains how to install and operate the Flowserve Limitorque MX/QX PROFIBUS field
unit, referred to as the MX (Multi-turn)/QX (Quarter-turn) PB (PROFIBUS) field unit. Actuators
containing the PB field unit may be connected by shielded twisted-pair, or shielded two-wire cable to
form a PROFIBUS communication system network. The name PROFIBUS is derived from Process
Fieldbus. The PROFIBUS communication system is a digital, serial, two-way open bus system that
supports a variety of communication rates. The MX/QX PB unit supports a communication rate up to
1.5 Mbit/sec. This system allows a network host station such as a distributed control system (DCS)
or a programmable logic controller (PLC) to control and monitor the actuators, including the acquisi-
tion of status and alarm data from each MX/QX.
