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.

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”.

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”.
GB
-- 7 --
bi10e001e
Node address
Switches 3 to 8 are used to set the node address. Switch 3 is the MSB, and switch 8
is LSB.
Address Sw 3 Sw 4 Sw 5 Sw 6 Sw 7 Sw 8

1 OFF OFF OFF OFF OFF ON
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.

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.

1 MACID Get_Attribute_Single Node Address. 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
Machine defined in Chapter
XX.
