1 INTRODUCTION TO DEVICE NET

DeviceNet is used for industrial automation, normally for the control of valves,

sensors, I/O units and other automation equipment.

The DeviceNet communication link is based on a broadcast--oriented,

communication protocol, the Controller Area Network (CAN).

This protocol has I/O response and high reliability even for dem anding applications,

e.g. control of brakes.

User organization

DeviceNet has a user organization, the Open DeviceNet Vendor Association

(ODVA), which assists members of matters concerning DeviceNet.

For further information, please contact ODVA on e--mail: [email protected]etcom.com or

at address:

1.1 Network overview

The media of the fieldbus system is a shielded copper cable consisting of one

twisted pair of communication cable and two cables for external power supply.

The baud rate can be changed between 125kbits/s, 250kbits/s and 500kbits/s, this

can be done in three different ways:

S first is simply by the DIP--switch

S second via the fieldbus

S third is auto baud rate setting.

The DIP--switches are found inside the Weld Data Unit.

-- 4 --

bi10a001e

1.2 Technical features for DeviceNet

Here follows a short list of some important features with the DeviceNet

communication standard:

S DeviceNet specific cable (twisted pair). S Protection for wiring errors.

S Access to intelligence present in low--level

devices, Master/Slave and Peer--to Peer

capabilities.

S Selectable data rates of 125kbit/s baud,

250kbit/s baud and 500kbit/s baud max.

T runk distance 500 meters and Drop length

156 meters at 125 kbit/s baud.

S T runk line – drop line configuration. S Adjustable power configuration to meet

individual application needs.

S Support of up to 64 nodes. S Provision for the typical request /response

oriented network communications.

S Node removal without severing the network. S Provision for the efficient movement of I/O

data.

S Simultaneous support for both

network--powered (sensors) and

self--powered (actuators) devices.

S Fragmentation for moving larger bodies of

information.

S Use of sealed and open--styled connectors. S Duplicate MAC ID detection.

1.3 Functional o verview

The Esab DeviceNet node is implemented according to the ODVA specification for a

communication adapter (profile no 12). It is acting as a ”group two only server” on

the DeviceNet network.

The module supports the following connection types:

S explicit messaging

S polled I/O

S bit--strobe I/O

S change of state / Cyclic I/O.

2 INSTALLATION AND CONFIGURATION

2.1 Network connection

This equipment is made with a “build in” drop line. Because of the restrictions in the

DeviceNet standard the maximum length between the Weld Data Unit and the

fieldbus connectors is limited to 6 meters ( 20 ft.).

This is shown in the picture below and is described in more detail in the “DeviceNet

specification”.

Connector

Signal Description

1 V-- Negative supply voltage

2 CAN_L CAN_L bus line

3 SHIELD Cable shield

4 CAN_H CAN_H bus line

5 V+ Positive supply voltage

2.3 Configuration

A connection to the node is set up towards the Assembly object with a bus

configuration tool or directly from a master.

Mac Id (Node address) and baud rate are configurated with a dip--switch in side the

Weld Data unit (see figure below). The range for M acId is between 0--63 and baud

rate is between 0 and 2 ( 0 = 125 kbit/s, 1 = 250 kbit/s and 2 = 500 kbit/s).

When the DIP--switch is in the ” ON” or ”Closed” position, the node interprets it as a

logic ”1”.

-- 7 --

bi10a001e

Node address

Switches 3 to 8 are used to set the node address. Switch 3 is the MSB, and switch 8

is LSB.

2 OFF OFF OFF OFF ON OFF

3 OFF OFF OFF OFF ON ON

62 ON ON ON ON ON OFF

63 ON ON ON ON ON ON

Baud rate

There are three different baud rates for DeviceNet;

S 125 kbit/s

S 250 kbit/s

S 500 kbit/s.

Choose one of them by setting DIP --switch 1 and 2 before configuration.

Baud rate, bits/s Sw 1 Sw 2

125k OFF OFF

250k OFF ON

500k ON OFF

Reserved ON ON

Termination

DeviceNet uses termination resistors at each physical end of the bus. T he

termination resistor should be 121 ohm. This should be connected between CAN_H

and CAN_L on the bus.

2.4 LED indicators

The node inside the Weld Data Unit is equipped with four bi--color status and

indication LED’s mounted at the front of the module.

There is also an additional bi--color Watchdog LED on the module inside the Weld

Data Unit.

Green Steady on Device operational

2.5 EDS file

Each device in a DeviceNet network is associated with a EDS file, containing all

necessary information about the device.

The network configuration program during configuration of the network uses this file.

The latest version of the EDS file can be received by contacting ESAB.

3 FUNCTIONS AND OPERATIONS

3.1 Memory structure for the ESAB DeviceNet unit

The interface from the fieldbus against the module is based on the standard

DeviceNet objects and five vendor specific objects. Most applications do not require

the usage of the vendor specific objects. The vendor specific objects can be used to

access different areas in the in the I/O memory of the Weld Data Unit.

For a complete description of the objects, please see chapter 4.1.

Type

1 MACID Get_Attribute_Single Node Ad-

dress.

The attribute contains the

MAC ID for this device. The

range of attributes is 0 to 63

decimal. A device that uses

switches to set MAC ID must

return an Error Response

whose General Error Code

is set to 0E (Attribute not

settable) to a Set_At-

tribute_Single Request

specifying the MAC ID

attribute. The exception to

this rule is that if the MAC ID

switches are not user

accessible when the product

is installed, then the

switches can be overridden

via a Set_Attribute_Single.

The MAC ID attribute is

considered non --volatile in

that once configured the

attribute must be remem-

bered after a power cycle or

a device reset. If the device

does not know what its MAC

ID is it should default to 63.

The modification of the MAC

ID requires a device to

delete all Connection

Objects and re--execute the

Network Access State
