Accessing the Main Page
The following steps will help you access the browser based configuration of the gateway. By default,
DHCP is enabled. If the gateway fails to obtain an IP address over DHCP it will Auto IP with 169.254.X.Y.
For more information on your Operating system network setting refer to the Accessing Browser
Configuration document from our support web site.
1) Scan the QR code on the back of the unit or navigate to www.rtautomation.com/460-gateway-support
and download IPSetup.exe.
2) Run the IPSetup.exe program.
3) Find unit under “Select a Unit”.
a. Change Gateway’s IP address to match that of your PC if DHCP has failed.
i. You will know DHCP has failed if the gateway’s IP address is AutoIP at 169.254.X.Y.
ii. If successful, it will say DHCP’d at ex: 192.168.0.100 or however your DCHP Client is set up.
b. If you do not see the gateway in this tool, then your PC is most likely set up as a static IP.
i. Change your PC’s network settings to be DHCP. If DHCP fails, then it will change to be on the
169.254.x.y network.
ii. Relaunch the IP Setup tool to see if gateway can be discovered now.
4) Click Launch Webpage. The Main page should appear.
Default setting is set to DHCP. If DHCP fails, default IP Address is 169.254.x.y

Error: Main Page Does Not Launch
If the Main Page does not launch, please verify the following:
1) Check that the PC is set for a valid IP Address
a. Open a MS-DOS Command Prompt
b. Type “ipconfig” and press enter
c. Note the PC’s IP Address, Subnet, and Default Gateway
2) The gateway must be on the same Network/Subnet as the PC whether it’s setup for DHCP or Static.
Once you have both devices on the same network, you should be able to ping the gateway using a MS-
DOS Command Prompt.
The Screenshot above shows a gateway that is currently set to a static IP Address of 192.168.0.100.
If you are able to successfully ping your gateway, open a browser and try to view the main page of the
gateway by entering the IP Address of the gateway as the URL.

Committing Changes to the Settings
All changes made to the settings of the gateway in Configuration Mode will not take effect until the
gateway is restarted via the webpage. Changes will not be stored if the gateway’s power is removed
prior to a reboot.
NOTE: The gateway does not need to be restarted after every change. Multiple changes can be made
before a restart, but they will not be committed until the gateway is restarted.
When all desired changes have been made, press the Restart Now button.
The webpage will redirect to our rebooting page shown below:
The reboot can take up to 20 seconds.
If the IP address has not been modified, the gateway will automatically redirect to the main page.
If the IP address was modified, a message will appear at the top of the page to instruct the user to
manually open a new webpage at that new IP.

Modbus TCP/IP Server Configuration
Click the Modbus TCP/IP Server button to access the configuration page.
1) Select which Network Interface to use for this Allen-Bradley PLC connection. If using single port
hardware, the Network Interface will default to Ethernet oort only.
2) Enter a Device Label to identify the device within the gateway.
3) TCP Port: Enter a TCP Port for the Modbus TCP server to listen on. Default for Modbus TCP/IP is 502.
4) Inactivity Timeout: Amount of time the gateway will wait for a read/write request before issuing a
timeout.
5) To enable data swapping, select the required Swap Indicator. If the bytes appear in the wrong
order, enable swapping to change the data. This swapping does NOT change coils and their ordering
inside the Bit Pack.
6) Bit Pack: Select the formatting of the Coil Status/Input Status. Automap will use this packing size to
map coils to/from the other protocol. The bit pack selection here should match that of the other
protocol. The starting address is considered Bit 0 and is the low-order bit.

Modbus TCP/IP Server Configuration-Data Groups
The bottom area of the Modbus TCP/IP Server Configuration page lets you configure up to 100 data
groups for both the read and write.
There are three ways to configure this protocol:
1) Auto-Configure Group by Device (Default)
2) Auto-Configure Group by Data Type
3) Manual Mode
NOTE: You may go back and forth between modes, but when reverting from Manual Mode to either of
the two Auto-Configure modes, all changes made in Manual Mode will be discarded.

Auto-Configure Group by Device vs. Auto-Configure Group by Data Type
There are two different methods for Auto-Configure: Group by Device or Group by Data Type.
There are a couple of rules to keep in mind when using Auto-Configure Mode:
1) If the other protocol inside the gateway is a server, slave, or adapter protocol, then there are no
differences between the Auto-Configure modes.
Group by Device (Default Method)
Group by Device goes through the other protocol on the gateway and auto-configures the data groups
in the Modbus TCP/IP server for all the data points on the other protocol’s first device. After it finishes
with the first device, it will auto-configure all the points for the second device (if one is configured), and
so on.
The data in this method is not optimized- there could potentially be a lot of wasted/unused data space,
but it will be organized more logically from the master/client’s point of view.
Group by Data Type
Group by Data Type goes through the other protocol on the gateway and auto-configures the data
groups in the Modbus TCP/IP server for all the data points within the other protocol.
Another way to view this option is to say that the data points allocated are packed together so there is
very little wasted data space. The data is packed or optimized.
Example:Protocol A is a master/client protocol that has 2 devices with the same setup:
Device_1 has 1 integer scan line, 1 float scan line, 1 integer scan line- each for 1 point of data
Device_2 has 1 integer scan line, 1 float scan line, 1 integer scan line- each for 1 point of data
Protocol B is a server/slave/adapter protocol that can be mapped as follows:
Group by Device - Protocol B will have 4 scan lines that will look like the following: Scan Line 1 and 2 will
represent Device_1 and Scan Line 3 and 4 will represent Device_2.
Scan Line 1 => Type Integer, length of 2
Scan Line 2 => Type Float, length of 1
Scan Line 3 => Type Integer, length of 2
Scan Line 4 => Type Float, length of 1
Group by Data Type - Protocol B will have 2 scan lines that will look like the following: All like data types
from Device_1 and Device_2 will be combined.
Scan Line 1 => Type Integer, length of 4
Scan Line 2 => Type Float, length of 2
