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).

The index is the relative position of the ELC-CODNETM module to the left side of the ELC
processor. The 1st module left of the ELC processor is index number 1. The next module to
the left is number 2. The others are indexed as 3, 4, and so on.

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

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
