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.

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

1.5.1.1ꢀ NetworkꢀSpeciﬁcations

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.

2.2.3 Hardware interface

The DeviceNet Limitorque Interface is comprised of a minimum of one PCB with two interfaces - One

for the DeviceNet Terminal Block connector and one for the SMT Main Board.

Figure 2.3 gives an overview about the hardware. The microcontroller on the DeviceNet Limitorque

Interface handles the DeviceNet protocol, stores the DeviceNet parameters in an EEPROM, and commu-

nicates with the SMT Main Board via SPI.

Figure 2.3 – DeviceNet Limitorque Interface

2.2.4 Network Cable

DeviceNet is a CAN - based protocol that uses 5 wires including a shield. Two of the conductors are

used for 24V DC power & up to 8 amps (4 amps for NEC Class 2) may be passed along the hi-way from

a suitable power source. Two conductors are used for the CAN bus signals, CAN_H and CAN_L, which

are usually smaller in diameter. Limitorque recommends Belden cable for connecting to a DeviceNet

network. The speciﬁcations for thick and thin cable (per site requirements) are as follows:

3 Installation and Conﬁguration

3.1 Site and Network Cable Preparation

3.1.1 Site Preparation

Prepare the site and associated equipment for operation of the DeviceNet controlled MX actuators as

follows:

1. Prepare a detailed site plan consisting of the following:

• Actuator locations, tag numbers, DeviceNet addresses

• Junction boxes, terminal strip locations, and tag numbers

2. Provide free access to the MX control panel and terminal block for setup, conﬁguration, and

troubleshooting.

3. Prepare cable and label all wires. See Section 3.1.2, Network Cable Preparation.

4. Install power and control wires in separate conduits. Shielding is not sufﬁcient to prevent induction

of stray voltages onto signal leads from the power lines.

5. Install and verify earth grounds.

NOTE: Limitorque deﬁnes an effective local earth ground as a low impedance (less than 5 ohms) path

to:

• A ground electrode placed in close vicinity of the actuator that is free of ground loop currents. OR

• A safety ground that is free of ground loop currents running from the actuator back to the system

ground electrode. If the signal wiring is run on aerial cable where it may be exposed to high-

energy electrostatic discharge (such as lightning), a low impedance path to ground that is capable

of high current must be provided a short distance from the actuator as described above. OR

• A power distribution grid identifying the impact of power isolation to a particular actuator or

group of actuators should be provided.

3.1.2 Network Cable Preparation

3.1.2.1ꢀ NetworkꢀCableꢀConnectionꢀtoꢀtheꢀFieldꢀUnitꢀ

The DeviceNet ﬁeld unit is connected to the network via the MX terminal block. The network cable is

connected to the terminal block as shown in Figure 3.1.

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

Figure 3.1 – Network cable connection to terminal block

NOTE: Recommended DeviceNet cable is Belden 3084A or equal. 121 ohm, ¼ W +/-1% termination

resistors must be connected at each segment end. Customer is required to connect wire between

terminal 30 and chassis ground for surge protection. Preferred network wiring is to connect shield to

terminal 48 for only one unit on each segment. Connect remaining individual network cable shields

together to ensure proper shielding of entire network. Consult wiring diagram for exact terminal

connection points as they may change.

Prepare the network cable for connection to the MX terminal block as follows.

a CAUTION: Strip stranded conductors carefully; do not damage the strands. This will weaken the

conductor. Do not nick conductors or conductor insulation when stripping away the insulation.

Nicking stresses the conductor and can cause the conductor to break. This type of damage may

not be apparent and failure can occur later without warning.

NOTE: Excess cable should be cut, not coiled or looped, to prevent noise induction into the network and

to reduce signal loss through unnecessarily long cable runs.

CableꢀPreparationꢀ

1. Remove two to three inches (5 to 8 cm) of the outer plastic jacket.

2. Separate the cable parts. Unbraid the shield and peel back the foil shield to the same point where

the outer jacket was removed. Cut away the braided shield and the foil shield. Strip the insulation

from the conductors approximately 0.4 inch (1 cm).

3. Apply heat shrink tubing to insulate the drain wire and to provide stress relief to the cable.

a CAUTION: Do not melt the insulation. NOTE: Ungrounded drain wires should be cut even with

the cable sheath. The brand foil and drain wire should have heat shrink tubing applied.

4. Install ring tongue connectors. Flowserve recommends the use of Thomas & Betts #RZ22-6 for

optimum results.

5. Connect the network cables to the MX terminal block as shown in Wiring Diagram #18-499-0038-3.

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

NOTE: Ground each segment of the cabling at only one point to prevent ground loops, which can affect system

performance. Verify the actuator is properly grounded.

6. Install jumper cable from terminal block pin 30 to earth ground or ground lug.

3.2 Installation Veriﬁcation

3.2.1 Network Cabling Installation Veriﬁcation

After installation is complete and prior to operation, inspect the network cable and its connection to

each ﬁeld unit for the following:

NOTE: Units should be disconnected from power. Network should be disconnected from host.

1. There should be:

• No nicks in the insulation—this can cause a short between conductors or to the grounded shield.

• No cut strands in a stranded conductor—this can cause a poor connection and eventually an

open circuit.

2. Verify that there is data wiring on each actuator per wiring diagram.

3. Cable armor should not be shorted to the cable shield/drain wire. Cable armor may not be at ground

potential and could be subject to lightning surges.

The shield/drain wire should only be grounded at one end of each cable segment (the section between

adjacent actuators between the host system and an actuator) to avoid ground loop problems.

The ground/earth connection should be at true ground potential and effective at all times. See Section

3.1.1, Site Preparation.

3.2.2 DNFU Installation Veriﬁcation

NOTE: Connect to either 24 V DC power or mains and activate power.

Verify the ﬁeld unit is installed as follows:

1. Enter the “SETUP” mode as detailed in Bulletin LMAIM1306/2306, MX Installation and Operation

Manual.

2. In the “SETUP” mode, use the black control knob to select “YES” to the main menu selection “VIEW

DIAGNOSTICS?”

3. Select “YES” to the display “VIEW HARDWARE STATUS?”

4. Select “YES” to scroll through the menu selections. The LCD will read “DeviceNet (OK) – NEXT?” if

installed.

NOTE: If the “DeviceNet (OK) – NEXT?” does not appear, contact Flowserve for assistance.

19. To return to the normal display, use the red knob to select either “LOCAL” or “REMOTE.”

DO_ESD_Chan can’t be written directly via the DeviceNet network, it is Read-Only. The attribute

Enable_Broadcast_ESD_Ctrl deﬁnes if a device is part of the broadcast ESD control scheme from Bit-

Strobe Connection or not. The resulting DO_ESD_Chan is deﬁned in the following table.

The MX allows the standard I/O connection to assert ESD, or the broadcast bit strobe connection to

assert ESD.

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

• International Product Name (Attribute ID 13)

• Semaphore (Attribute ID 14)

are not supported by DeviceNet Limitorque Interface.

Some of the instance attributes do not have any external interfaces, these values are managed directly in

the DeviceNet Slave Software.

NOTEꢀ1: The Vendor ID is managed by the ODVA. Flowserve has already obtained a valid Vendor ID.

The Vendor ID will be assigned during compile time as a constant of the DeviceNet Slave Software and

stored in Flash-Memory of the DeviceNet Limitorque Interface. Thus it cannot be altered during runtime.

NOTEꢀ2: The Product Code of the DeviceNet Limitorque Interface has already been assigned by

Flowserve. It typically maps to a catalog or model number. The Product Code will be assigned during

compile time as a constant of the DeviceNet Slave Software and stored in Flash-Memory of the

DeviceNet Limitorque Interface. Thus it cannot be altered during runtime.

NOTEꢀ3: The Revision of the DeviceNet Limitorque Interface. Has already been assigned by Flowserve.

It typically links to the revision control system of a company. The format of the revision is Major.Minor,

starting with 1.1, because 0 is not allowed in CIP. The default value for this attribute is therefore 0x0101.

The revision must match the entry of the EDS-File delivered with the DeviceNet Limitorque Interface.

The Revision will be assigned during compile time as a constant of the DeviceNet Slave Software and

stored in Flash-Memory of the DeviceNet Limitorque Interface. Thus it cannot be altered during runtime.

NOTEꢀ4: The Status represents the current status of the device. Important here are the bits 8 to 11

which make faults visible to the user.

NOTEꢀ5: The Serial Number is used in conjunction with the Vendor ID to form a unique identiﬁer for

each device. Flowserve is responsible for guaranteeing the uniqueness of the serial number across all of

its devices. The SMT Main Board will initialize the DeviceNet Limitorque Interface with data every time a

loss of communication condition between the DeviceNet Limitorque Interface and the SMT Main Board

had occurred. A part of this initialization data will be a unique board ID coming from the SMT Main

Board. Upon reception of this unique board ID from the SMT Main Board, the DeviceNet Limitorque

Interface will construct a Serial Number value. The transducer/spi software will then get the currently

stored serial number value from the DeviceNet stack, compare it to the one just constructed based on

the data from the main board, and if different, set the new value in the Identity Object / EEPROM. Also,

if the values were different, the transducer / spi software will then request that the DeviceNet board

reset to it’s “factory default” non-volatile condition (exception: the serial number in EEPROM is not

overwritten again).

NOTEꢀ6: The Product Name should represent a short description of the product/product family

represented by the product in attribute 3. It is limited to 32 characters. The product name should default

to “Limitorque”. However, at “spi initialization time”, the product name attribute can be updated by some

kind of API function call by the transducer / spi driver.

5.1 Checking the Normal Display

Place the selector switch in “LOCAL” or “REMOTE” position. The valve position will be indicated at the

top of the LCD. “STATUS OK” or “DNET COMM LOSS” should be indicated at the bottom of the LCD

display.

If “STATUS OK” is displayed, the DNFU is communicating with the DeviceNet network.

If “DNET COMM LOSS” is displayed, no communication is occurring. This could be due to a number of

factors, including problems with the host DeviceNet system and/or network. Check all local connections

and conﬁgurations. Conﬁrm that the host is connected, conﬁgured for baud rate, protocol to match

DeviceNet, and operational. See also Section 7, Troubleshooting.

9. Conﬁrm there are no duplicate DeviceNet addresses.

10. Conﬁrm that ground is at one end only per network cable segment.

11. Conﬁrm protocol, baud rate

Main power supply must be within +/- 10% of nominal unit power rating at all times. Refer to nameplate

for voltage.

UPS of 24 V DC must be within +/- 10% at all times.

7.1 Workmanship

The Limitorque MX is non-intrusive which facilitates ease of conﬁguration without removal of the

controls cover. Removal of the controls cover without permission from Flowserve can void the warranty.

Practice all plant and safety codes and standards. Failure to follow instructions can result in personal

injury and/or property damage.

Do NOT remove covers of Division 1 units with power applied to prevent the possible ignition of

hazardous atmospheres.

Qualiﬁed technicians should perform all service. Dangerous voltages may be present on the circuit

boards and terminations.

Use extreme caution when working around power input cables. These cables have potentially lethal

voltages on them.

Replace fuses only with speciﬁed parts for continued safe operation.

Have qualiﬁed personnel verify all wiring and connections against vendor drawings prior to energizing

the equipment. Incorrect wiring and/or connections can result in equipment damage.

a CAUTION: There is potential to cause electrostatic damage to electronic components. Before

handling electronic components, ensure that you are discharged of static electricity by brieﬂy

touching a grounded metal object.

The circuit boards in the MX DeviceNet contain components that are subject to damage from electro-

static discharge (static electricity). The following precautions and procedures are recommended when

handling circuit boards and components. Failure to observe these practices when handling and shipping

circuit board products may void your warranty.

• Keep plastics and other materials prone to the buildup of electrostatic charges (static electricity) away

from boards, components, and work area.

• Avoid synthetic or wool clothing; wear cotton or cotton blend materials. Keep components and circuit

boards away from clothing and hair.

• Discharge static electricity on your body by touching and momentarily holding a grounded metal

object before handling electronic components. This is especially important after walking across

carpeted areas.

3ꢃ
