Limitorque MX DeviceNet Field Unit  FCD LMENIM2328-00 – 11/05

1 Introduction

1.1Purpose

This manual explains how to install and operate the Limitorque MX™/DeviceNet field unit (DNFU) and is to be used as an addendum to Bulletin LMENIM2306, Limitorque MX Installation and Operation Manual. Up to 63 actuators, each containing a DeviceNet field unit, may be connected by a single 5 strand, twisted-pair cable to form a DeviceNet network, two wires for connection to the data highway and two wires for connection to the DC power lines of the network highway, plus a screen connection. A suitable power supply and termination resistors on the highway are required in order for the FU to function correctly. This network permits the actuators to be operated by various control room devices such as a distributed control system (DCS), a programmable logic controller (PLC), or a personal computer (PC). The DeviceNet system communicates status and alarm data from each MX actuator.
