1 Introduction

1.1 Purpose

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.

1.2 How to Use this Manual

Each section provides the MX user with information on installing and operating the MX DNFU.

Section 1, Introduction: Details user safety and knowledge requirements, system capabilities, and

features.

Section 2, System Components: Focuses on the description of the DeviceNet system hardware and

software components.

Section 3, Installation and Conﬁguration: Provides details for installing and conﬁguring a DNFU.

Section 4, Object Model Diagram: Provides a list of inputs and outputs supported through the Assembly

Object system information.

1.3 User Safety

Safety notices in this manual detail precautions the user must take to reduce the risk of personal injury

and damage to the equipment. The user must read and be familiar with these instructions before

attempting installation, operation, or maintenance. Failure to observe these precautions could result

in serious bodily injury, damage to the equipment, warranty void, or operational difﬁculty. User must

follow local and state safety regulations.

Safety notices are presented in this manual in three forms:

WARNING: Refers to personal safety. Alerts the user to potential danger. Failure to follow

warning notices could result in personal injury or death.

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

CAUTION: Directs the user’s attention to general precautions that, if not followed, could result in

personal injury and/or equipment damage.

NOTE: Highlights information critical to the user’s understanding of the actuator’s installation and

operation.

1.4 User Knowledge

It is recommended that the user read this manual in its entirety before the DeviceNet equipped actuator

is installed and operated.

The user needs to have a fundamental knowledge of electronics and microprocessor concepts. An

understanding of valve actuators and digital control systems is also of beneﬁt to the DNFU user.

1.5 DeviceNet System Capabilities and Features

DeviceNet is a low cost communications protocol which permits up to 64 nodes (devices) to be

installed over a single network and is based upon CAN (Controller Area Network), a broadcast protocol

developed for the automotive industry. DeviceNet™ protocol is deﬁned as an open network standard and

Limitorque’s device is certiﬁed for use by the ODVA, Open Device Standard Association. DeviceNet is

usually PLC input controlled and the Limitorque MX electronic actuator is well suited for this communi-

cation system. A typical network is seen in Figure 1.1.

Figure 1.1 – Typical Network

1.5.1 General Speciﬁcations

1.5.1.1 Network Speciﬁcations

DeviceNet is a digital, trunk/drop network that connects and serves as a communication network

between industrial controllers and I/O devices.

DeviceNet follows the Open Systems Interconnection (OSI) model, an ISO standard for network

communications that is hierarchical in nature. Networks that follow this model deﬁne all necessary func-

tions from the physical implementation up to the protocol and methodology to communicate control

and information data within and across networks.

Galvanical Isolation: The isolation voltage for the DNFU is up to 1,500 VRMS for 1 minute (1,800

VRMS for 1 second

Power Supply: The DNFU Interface will be powered from the DeviceNet bus. A switching regulator is

used to generate the internal supply voltage: VCC nominal 5.0 V ± 5 %

Surge Suppression: The DNFU Interface is equipped with surge suppression for the DeviceNet

network data and power lines. Surge suppression is compliant with IEC 61000-6-2:2001.

Environmental conditions

The DNFU environmental parameters are within the same environmental constraints as the actuator.

2 System Components

2.1 Introduction

This section gives an overview of the components used in the DeviceNet system. The ﬁeld unit is

installed in each MX actuator. The network cable connects the ﬁeld unit to the network via the actuator

terminal block. The network cable is connected to a host controller, typically a PLC.

2.2 Hardware

NOTE: Recommended storage procedures are detailed in Bulletin LMAIM1314 Limitorque MX

Maintenance and Spare Parts Manual. Failure to comply with recommended procedures will void the

warranty. For longer-term storage, contact Limitorque for procedures and recommendations.
