This document will go over the procedure for setting up the Ethernet RAC with one or more
serial-to-Ethernet gateways for use in a customer’s ATS controller network. Supported gateways
are the PXG200/600/800E Power Xpert Gateway series and the ELC-CAENET Ethernet module.
Supported controllers are the ATC-300+, 600, 800, and 900.

General Operation Theory
With the release of the new Ethernet-enabled RAC’s (HMIVU07CUNBE, HMIVU08CUNBE, and
HMIVU10CUNBE), it is now possible to monitor any number of ATS switches (up to 8 switches
per RAC) in a facility with Ethernet networks. The Eaton PXG-200E/600E/800E provides an easyto-manage serial Modbus to “Modbus TCP/IP” gateway. If the Power Xpert monitoring is not
necessary, the Eaton ELC-CAENET module provides the same serial-to-Ethernet gateway
functionality as the PXG series for RAC connectivity.
With proper configuration and coordination from the customer’s IT department, it is possible to
install multiple gateways on an existing network, allowing them to attach an RAC on any
Ethernet port throughout their facility. Note: Due to the nature of the HMI addressing, it is
necessary that each Ethernet HMI is configured either before shipping (if gateway IP and
controller Addresses are known first), or by an on-site technician.
Preparing PXG Gateways





Connect the first PXG gateway to your PC via USB cable and power the unit up. It will
take about 2 minutes before it is ready to use (indicated by solid power light with no
other lights on).
Open a web browser and enter the following URL (on an un-programmed PXG only):
http://10.23.6.5/ (Note, your IP may be different from the Factory).
The username/password is: admin/admin
On the left column, click the Network Config. link, and the following screen will open:
You’ll need to configure your Static IP, Netmask, Gateway, and DNS Server for the PXG.
If you won’t be connecting to an existing network, then this can be setup however you
wish. If you are connecting to an existing network, you will need to coordinate these
settings with the site’s IT department. Note that each gateway on the same subnet


MUST have a unique Static IP Address. The Netmask, Gateway, and DNS Server settings
will depend on the existing network setup.
Next, navigate to the Modbus TCP menu on the left column; it will open this screen:
You will want to click the Enable and Enable Writes check-boxes. Enter the port (the
default is 502) that the Modbus TCP packets will be sent to/from. Note: Make sure that
this port is open and forwarded correctly in any firewalls/routers on the network. Set
your com timeout (default of 10000ms is fine).
The final task is to setup either COM 1 or INCOM. If you are using ATC-300+/900’s, you
will use COM1. If you are using ATC-600/800’s with IPONI’s, you will use INCOM. Click
on the appropriate button in the left column and you will see one of these screens:
Your configuration should match these unless you manually changed the Baud Rate (or
Parity in an ATC-900) of the ATS controllers to something other than 9600.


Next you will want to add your ATC-300+/900 or ATC-600/800 to your device list.
Consult the PXG gateway instruction booklet for help on this process.
o Note: If you are adding an ATC-600/800, you will want to take note of the
Modbus TCP UID (cached) number that gets assigned to your controller (circled
in red). This is the address you will be using as your “PLC Station Number” while
configuring the HMI software later in this document.

Your PXG Gateway is now configured to convert RS-485 Modbus (or INCOM) to Modbus
TCP/IP.
Repeat this process for any additional PXG gateways you may have, making sure that
each one has a unique IP.
You should now save your PXG configuration(s) as an XML file by clicking on
Save/Restore Configuration. This will be very useful if the customer ever needs a
replacement PXG unit sent out to them.

Preparing ELC-CAENET Modules





Download and install ECISoft from Eaton’s website.
Connect your ELC-CAENET module to your PC either via the serial port or the Ethernet
port on the module.
Connect 24 Vdc to the CAENET using the provided wiring connector.
Open ECISoft and go to Tools -> Communication Setting
Select your Communication Type (RS232 if using the serial cable, or Ethernet if using an
Ethernet cable)
o For RS232
 COM Port: set to whatever port your serial cable is connected to on your
PC
 Data Length: 8; Parity: Even; Stop Bits: 1; Baud Rate: 9600
 Station Address: 1; Modbus Mode: RTU
o For Ethernet
 No settings







Configure your IP Address, Netmask, and Gateway IP addresses based on the customer’s
desired network configuration. Make sure the IP Configuration is set to “Static”.
Click on the “Gateway” tab. This will show you a menu with 3 more tabs: COM Setup, Bit
Device, and Word Device.
Click on the COM Setup tab, if it isn’t already selected. Here you will configure the COM
Mode, Baudrate, Parity, Data Length, Stop Bits, and Station Address (see below).
Set COM2 Mode (RS-485) to “Modbus RTU Master”.
Baudrate, parity, stop bits, and station address must all match your ATC controller
settings.
o Baudrate: For an ATC-600/800 should match the baud rate selected on the IPONI
module. We recommend IPONI baud rate ALWAYS be set to 9600. The ATC-300+
and 900 have adjustable baud rate setpoints (minimum of 9600).
o Parity and Stop Bits: If you are using an ATC-300+, 600, or 800, the Parity is
always “None”, and the Stop Bits is always “1”. If you are using an ATC-900, the
parity and stop bits are adjustable, so make sure they match your settings here.
o Station Address: Set this to an unused address on your Modbus serial network.
This should not match any existing device’s station address.
Click OK and your settings should be uploaded to the ELC-CAENET. Your CAENET
gateway should now be properly configured to send data between serial controllers and
the Ethernet HMI.

Configuring the HMI




First, we’ll want to be sure the Ethernet setup on the HMI is configured to connect to
the PXG(s) and the existing Ethernet network (if there is one).
Open your HMiSoft file, enter the password, and navigate to Options->Communication
Setting. Click on Ethernet. Your screen should look like the following:
Click on Link1 under the Link Name category (circled in orange).
Enter the your TCP/IP gateway’s static IP address in the “Controller : Port” field, and
make sure your port # matches the port setting in the gateway (502 in this example).
o

To work with the default HMI setup, each of your controllers should have a unique
Modbus Address, starting with 1.
o If you have more than one gateway to connect to your controllers, then you will
need a custom HMI file with a new link for each gateway. Controller Modbus
addresses will also need to be known for each controller behind the gateways.
Set your “PLC Station” to match each controller’s assigned Modbus Address (or
“Modbus TCP UID (cached)” number if using an ATC-600/800 with a PXG).
Next, click on “Local Host” (circled in orange below). This will let you configure the HMI panel’s
IP address, subnet mask, gateway IP, and upload/download port. You will want to coordinate
with the plant IT dept. on available IP addresses for your HMI, and which gateway IP to use to
ensure a connection to the PXG or CAENET.



Make sure the “Overwrite IP” box is checked and enter in the IP address that the HMI
should have. Note: if the HMI will be connected to a DHCP server, you can simply click
the “Obtain an IP address automatically” checkbox to have the IP set via DHCP.
The Upload/Download port is for sending programs to the HMI remotely if you are
connected to the same network as the HMI. This port will need to be open and correctly
forwarded if there are any firewalls/routers in front of the HMI panel network if you
wish to use that feature.
Your HMI and gateway should now be properly configured. If possible, a quick connectivity
check should be done with the hardware in-house before shipping to the customer. This will
give you confirmation that your settings are correct and everything is working. However, this
will most likely not be possible if there are existing routers/firewalls in the setup.
Preparing the ATC-300+
The only options that need to be changed on the ATC-300+ are “Address” and “Baud Rate”.

Navigate to the Address setpoint and make sure that each controller in your network has a
unique Modbus address number. This address MUST match the PLC Station you set in your HMI
program above.
Next, navigate to the “Baud Rate” setpoint, and make sure it is set to match the baud rate you
set in the PXG COM 1 setting in the beginning of this document. The default is 9600.
Preparing the ATC-600/800
The controller itself does not have any affected setpoints. What we are interested in is the
IPONI attached to the controller.
Locate the 3 address selector switches and turn them to match the “Address (hex)” you entered
in your PXG configuration earlier. This number is different from PLC Station you set in your HMI
program above.
Next, locate the Baud Rate selector switch, and make sure it is set to match the baud rate you
set in the PXG COM 1 setting in the beginning of this document.
Preparing the ATC-900
To set up the ATC-900, we need to adjust the Modbus Address and the Modbus Configuration
setpoints. Use the pushbuttons on the front panel to go to “Change Setpoints”, enter your
password, then select the “Next” screen button to get to System Setup (2 of 3). Here you will
see the Modbus setpoints at the bottom.
Navigate to the Modbus Address setpoint and set this to match the PLC Station you set in your
HMI program above. Make sure that each controller on your serial network has a unique
Modbus Address.
Next, navigate to the Modbus Configuration setpoint, and make sure it is set to match the baud
rate, parity, and stop-bits you set in the PXG COM 1 setting on Page 2 of this document.
