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.

Configuring Read and Write Scan Lines
Follow these steps to manually configure read and write scan lines.
1) Click the View Read Scan Lines or View Write Scan Lines button.
2) Select a Point Type for each scan line. Options include: 8 Bit Int, 16 Bit Int, 32 Bit Int, 32 Bit Float,
Bool, Char.
a) Char Point Type: When using a Char Data Type, the 1st byte of each Memory address is reserved
for the Length field. The remaining bytes will be used for the actual data. You must use an array
of Char. String data type is not supported.
3) Select an Address Name- Choose if the data address is an input address(I), output address(Q) or
Data Block(DB#).
a) Note: Input address(I) is only available in the RTA gateway write direction (460SC to S7)
4) Enter a Byte Offset - Enter the first data address you want to read/write within the scan line.
5) Enter a Bit Offset - Only for Bool data type. Enter the offset to the desired bit of the data address
you want to read/write within the scan line.
a) Bits are organized from left to right, 7 down to 0. The value will be set to 0 for non-Bool data
types.
6) Enter the # of consecutive points to read for that point/data type. See the Scan Line Data Limit
section at the bottom of the webpage for max values in a scan line.

Example 1: 8 Bit Int, I Address, Byte 10, Offset 0, with # of Points 5 will read memory addresses IB10 to
IB14.
Example 2: 16 Bit Int, Q Address, Byte 10, Offset 0, with # of Points 5 will write memory addresses IW10
to IW19. Address 10-11 will be first 16-bit int, 12-13 will be the second 16-bit int, etc.
Example 3: 32 Bit Float, I Address, Byte 10, Offset 0, with # of Points 5 will read memory addresses ID10
to ID29. Address 10-13 will be first 32-bit float, 14-17 will be the second 32-bit int, etc.
Example 4: 16 Bit, DB5 Address, Byte 10, Offset 0, with # of Points 5 will read memory addresses of
DB5.DBX10. Address DB5.DBX10 will be first 16 bit, DB5.DBX12 will be next, etc.
Terminology Note and Example: I addresses refer to input, Q addresses refer to output, %B refers to
bytes and %W refers to words %D refers to DWord. Example, %IB68 would be used to read the byte
offset based on the number of points. If reading a input/output for Bool, the bit offset would read
the bit. Example, %I68.0 - %I68.7 or %Q68.0 - %68.7
