1 Introduction
The ELC-COENETM is an Ethernet communication module for remote configuration,
monitoring and control. It` supports the `Modbus TCP communication protocol as both a client
and server device. Acting as a server device, the ELC-COENETM provides remote monitoring
from SCADA (Supervisor Control and Data Acquisition) software or HMI (Human Machine
Interfaces) panels.Acting as a client device, the ELC-COENETM can poll server devices such
as VFDs and remote I/O products for use in the ELC control program.
In addition to Modbus TCP support, the ELC-COENETM module allows the ELC control
program to be remotely monitored and updated from ELCSoft or EIPSoft over Ethernet. It also
provides email support for event notification and provides for ELC clock synchronization from
an NTP server.

5.2 Changing the ELC-COENETM module name and IP address settings
(1) After you open the setup dialog you will be on the Basic tab. You can modify the module
name for easier identification.
(2) Next, set up the new IP address for the ELC-COENETM. First switch to “Network” setup
page. If there is a DHCP server on the LAN, you may select DHCP in “IP Configuration”.
If there is no DHCP server on the LAN, you must set a static IP. Please note that the
settings for subnet mask and gateway have to be the same as the settings in the same
LAN. Press “OK” to complete the setting, and ELCSoft will automatically search for the
ELC-COENETM again.
(3) The module name and IP of ELC-COENETM have been modified into new settings
(TEST1: 172.16.156.68).

ELC-COENETM

(4) Click on EATON ELC-COENETM, and ELCSoft will be able to communicate with the
ELC controller (e.g. uploading/downloading program or monitoring devices) via Ethernet.
5.3 Setting up and Clearing a Password
(1) Follow the steps in: Connecting the PC to the ELC-COENETM through a LAN
(2) Open the setup page and switch to the “Security” page.
(3) Check “Modify” box and enter “aabb” in “Password” and “Confirm Password" columns.
Click on “OK” to save the password.
(4) Open the setup page again. The ELC-COENETM is now locked by the password. You

ELC-COENETM
MN05006001E For more Information visit: www.eaton.com 11
cannot open any of the settings without entering the module password.
(5) To clear the password, simply leave the password columns blank. Click on “OK” to clear
the password.
5.4 Recovering from a lost password
(1) Use ELC-CBPCELC3 cable to connect the PC and ELC-COENETM and open the setup
page. Open the “Security” page.

(2) Check the “Factory Setting” box and the “Warning” dialog box will appear. Click on “Yes”
to return to default setting (in approx. 5 ~ 10 seconds), and the password will be cleared
as well.
Note: this action returns all parameters are to their default settings.
5.5 Setting IP Filter Protection to restrict access
(1) Follow the steps in: Connecting the PC to the ELC-COENETM through a LAN
(2) Open the setup page and switch to the “IP Filter” page.
(3) Check the “Enable IP Filter” box. Enter “192.168.0.4” in the No. 1 “IP Address” and
“255.255.255.255” in all “Subnet Netmask” columns.

5.6 Setting up E-Mail notification
(1) Follow the steps in: Connecting the PC to the ELC-COENETM through a LAN.
(2) Open the setup page and switch to "Mail” page.
(3) In the “Mail” page, enter the address of the SMTP server, subject of event (up to 4), and
mail address of the recipient. Next to the subject of event define the data you want to
include in the email for that event.
(4) Check all the events that you want to trigger emails to “Recipient 1”. Click on “OK” to
complete the setting.
(5) The emails are triggered by writes to the appropriate CRs of the ELC-COENETM module
(CR#3-CR#6). After all the settings in ELC-COENETM are completed, enter a program
that loads the CR registers based on desired trigger event, compile the ladder diagram
and download it to the MPU. An example program is shown below

5.7 Setting up Data Exchange between ELC processors
This application example will demonstrate how to configure an ELC-COENETM Ethernet
module to read and write data to another ELC-COENETM/ELC-PV controller. These messages
may be set up to be sent continuously without ELC-PV control or triggered by the controller. The
software used to configure the messages is called ECISoft and is included in ELCSoft.
The system used for this application example consists of the following:
(2) ELC-PV28 controllers
(2) ELC-COENETM Ethernet modules (Modbus TCP protocol)
(1) ELC-PS01 24vdc power supply
(1) Ethernet switch 10/100mbps
(3) Ethernet patch cables
Both Ethernet modules are connected to the switch along with the computer running ELCSoft.
The Subnet mask used for all devices is: 255.255.255.0. The IP addresses used for each
device are:
1. ELC-COENETM ( message initiator) 120.151.1.2
2. ELC-COENETM (message receiver) 120.151.1.4
3. Computer running ELCSoft 120.151.1.1

Setting up messages in an ELC-COENETM module using ECISoft
Start ELCSoft, then click the button shown below to start ECISoft. When holding the curser over
the button, it will display ECISoft. Use this to verify that you’re clicking the correct button.
ECISoft will look like the following:
The ELC programming cable (ELC-CBPCELC3) may be used to connect to and configure each
Ethernet module or Ethernet may be used to connect to both modules. For this example,
RS232 was used to initially configure the IP address and Subnet Mask for each Ethernet
module. The Ethernet modules do support DHCP. Note: the default IP address setting for the
ELC-COENETM module is IPaddress 192.168.1.5. The PC IPaddress and network mask need
to be set up to reside on the same network as the ELC-COENETM. This will allow you to
connect to each module using ECISoft on Ethernet. If you choose to use RS232 to configure
the Ethernet modules, use the ELC programming cable to connect to each Ethernet module to
set the IP address and Subnet Mask. The computer and both Ethernet modules must then be
connected to an Ethernet switch. Be sure the subnet mask is the same for all devices.
Select the Tools drop down menu then choose Communication Setting. For this example the IP
addresses are set up for each device as shown earlier in this document. The Communication
Setting page looks like the following:

ELC-COENETM
MN05006001E For more Information visit: www.eaton.com 17
Click OK after selecting Ethernet for the Type. Then in ECISoft, click the IP “magnifying glass”
and the software will search for all ELC Ethernet devices connected to the same Ethernet
network. When complete, the following screen will be displayed:
To access the configuration pages for each module, double click its icon. When the icon for the
first ELC-COENETM module is double clicked, the following window will open:

ELC-COENETM
18 For more Information visit: www.eaton.com MN05006001E
The Overview window displays specifics about each module. The Basic tab allows the IP
address to be changed as well as the subnet mask and gateway address. This is also where
the IP address can be made Static or DHCP. Be sure Modbus TCP is enabled in the bottom left
portion of the screen. When finished, the Basic tab looks like the following for this example:
Configure the other Ethernet module in the same manner. The Ethernet module at IP address
120.151.1.4 will only require setting up the IP address, subnet mask and optional gateway
address. It will only be receiving messages from the other Ethernet module.
Setting up peer-to-peer Ethernet messages in an ELC-COENETM module.
From ECISoft, open the Data Exchange tab for the Ethernet module at IP address 120.151.1.2.
It looks like the following:
