Introduction

3This is an OPEN-TYPE device and therefore should be installed in an enclosure free of airborne

dust, excessive humidity, shock and vibration. The enclosure should prevent non-maintenance

staff from operating the device (e.g. key or specific tools are required to open the enclosure) to

avoid potential equipment damage or personal injury. DO NOT touch any terminal when the power

is switched on.

3Please read this manual carefully and follow the instructions to avoid damage to the product or

personal injury.

1 Introduction

DeviceNet is an international, open and vendor- independent communication protocol widely

applied in industrial and process automation.

The ELC-CODNETM provides the ability for an ELC-PV processor to exchange data on a

DeviceNet network. The ELC-CODNETM can act both as a DeviceNet master and as a

DeviceNet slave.

Features

zSupports DeviceNet master and slave modes

zAs a master the CODNETM supports polled, bit-strobe, change of state and cyclic I/O

messaging.

zProvides continuous I/O scanning of slave devices

zProvides explicit messages triggered by ELC program

zSupport EDS file configure in ELCSoft software

zConnection size is flexible from 1 to 380 bytes in the input and output area

Cable Length and Baud Rates

The maximum cable length in a segment depends on the transmission speed. DeviceNet

communicates at speeds from 125kbps to 500kbps over distances from 100 to 500 meters.

Baud rates (bps) 125k 250k 500k

Length (m) 500 250 100

If you need more information on installing a DeviceNet network, see “DeviceNet Planning

and Installation Manual” available from ODVA.org.

5 Input and Output Image mapping

Data exchange between ELC-CODNETM Scanner and the ELC processor

When the ELC-CODNETM scanner is connected to the ELC processor, it will map to a

section of the ELC processor data area (D registers).

6 Application

6.1 Using the CODNETM module as a polling master

The ELC-CODNETM module is a polling master on DeviceNet that also supports slave

mode at the same time. The CODNETM module is configured using the DNET CONFIG tool

located in ELCSoft. Click the icon shown below to run DNET CONFIG.

When the DNET CONFIG icon is clicked, the following screen will open:

ELC-CODNETM

8 For more Information visit: www.eaton.com MN05006002E

To go online with the DeviceNet network, the computer must be connected to the ELC

controller which in turn is connected to the CODNETM module via the controller’s left-side

bus. In the DNET CONFIG software, select Setup, followed by Communication Setting, then

System Channel. The following screen will open:

These are the default communication parameters. Be sure to select the correct COM port

on your computer that is being used to connect to the ELC controller with the

ELC-CBPCELC3 programming cable. When the cable is connected and the interface

parameters are set, click the Network drop down menu and select Online and the following

screen will open:

In this case there is only one master communication module connected to the left-side bus
