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 Access Browser
Configuration Doc on the CD or download from our support web site.
1) Insert the provided CD-ROM into a computer also on the network.
2) Run the IPSetup.exe program from the CD-ROM.
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.
oIf the IP address has not been modified, the gateway will automatically redirect to the main page.
oIf 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.

External PLC Configuration
The bottom area of the Allen-Bradley PLC Configuration page lets you configure up to five PLCs.
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.
1) To add additional PLCs, click the -Select- dropdown under Allen-Bradley PLC Device List and select
Add Generic PLC option.
a) To remove a device, navigate to the server to delete using the << and >> buttons and click the
Delete PLC button.
b) To create a new PLC with the same parameters already configured from another PLC, click the -
Select- dropdown and select the Add from PLC X option (where X represents the PLC you wish
to copy parameters from). Once created, you can make any additional changes needed to that
new PLC.
NOTE: Auto-Configure Modes can ONLY be used in PLC 1.
2) To edit scan lines, you will need to go into Manual Configure Mode.

External PLC Configuration: Auto-Configure
While in either of the two Auto-Configure modes, the number of scan lines and the actual scan lines
themselves cannot be edited. Auto-Configure Mode looks at the other protocol and then configures the
scan lines within the PLC to match. The PLC Tag/File Names and Data Types will be defined after the
other protocol is configured.
If the PLC is a CompactLogix, ControlLogix or FlexLogix, the data will be configured according to the
following rules:
1) Any 8 Bit Signed/Unsigned data will be mapped as Sint.
2) Any 16 Bit Signed/Unsigned data will be mapped as Int.
3) Any 32 Bit Signed/Unsigned data will be mapped as Dint.
4) Any 32 Bit Float and 64 Bit Float data will be mapped as Real.
5) Any Coils or 1 Bit Binary Packs will be mapped as Bool (1 Bit).
6) Any Coils or 8/16/32 Bit Binary Packs will be mapped as Bit Array (32 bit).
7) Any String Data Types will be mapped as String.
If the PLC is a MicroLogix, SLC or PLC5E, the data will be configured according to the following rules:
1) Any 8 Bit Signed/Unsigned and 16 Bit Signed/Unsigned data will be mapped as Int.
2) Any 32 Bit Signed/Unsigned, 32 Bit Float, and 64 Bit Float data will be mapped as Real.
3) Any Coils or 1/8/16/32 Bit Binary Packs will be mapped as Bit Array (16 bit).
4) Any String Data Types will be mapped as String.
Regardless of PLC type, the following is also true:
1) The read or write direction depends on whether it is configured as a read or write on the other
protocol.
2) If the other protocol exceeds the number of Sint, Int, Dint, Real, Bool, Bit Array, or String data types
the Allen-Bradley PLC supports (see limits on webpage), then nothing will be mapped. You will see
the number of scan lines remain at 0 and the main page will display the following error:
a) To fix this error, simply decrease the amount of data you configured on the other protocol so
that the max number of Tag/File Name is not exceeded or call customer support to increase the
limits.

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
on the Allen-Bradley PLC 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 on the Allen-Bradley PLC 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: 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
