Assigning IP addresses to programming and network devices

If your programming device is using an on-board adapter card connected to your plant LAN (and possibly the world-wide web), the IP Address Network ID and subnet mask of your CPU and the programming device's on-board adapter card must be exactly the same. The Network ID is the first part of the IP address (first three octets) (for example, 211.154.184.16) that determines what IP network you are on. The subnet mask normally has a value of 255.255.255.0; however, since your computer is on a plant LAN, the subnet mask may have various values (for example, 255.255.254.0) in order to set up unique subnets. The subnet mask, when combined with the device IP address in a mathematical AND operation, defines the boundaries of an IP subnet.

Note In a world-wide web scenario, where your programming devices, network devices, and IP routers will communicate with the world, unique IP addresses must be assigned to avoid conflict with other network users. Contact your company IT department personnel, who are familiar with your plant networks, for assignment of your IP addresses.

Assigning or checking the IP address of your programming device using "My Network Places" (on your desktop)

You can assign or check your programming device's IP address with the following menu selections:

• (Right-click) "My Network Places"
• "Properties"
• (Right-click) "Local Area Connection"
• "Properties"

In the "Local Area Connection Properties" dialog, in the "This connection uses the following items:" field, scroll down to "Internet Protocol (TCP/IP)". Click "Internet Protocol (TCP/IP)", and click the "Properties" button. Select "Obtain an IP address automatically (DHCP)" or "Use the following IP address" (to enter a static IP address).

Note Dynamic Host Configuration Protocol (DHCP) automatically assigns an IP address to your programming device upon power up from the DHCP server.

Checking the IP address of your programming device using the "ipconfig" and "ipconfig /all" commands

You can also check the IP address of your programming device, and, if applicable, the IP address of your IP router (Gateway) with the following menu selections:

• "Start" button (on your desktop)
• "Run"

In the "Run" dialog, in the "Open" field, enter "cmd" and click the "OK" button. In the "C:\WINDOWS\system32\cmd.exe" dialog that is displayed, enter the command "ipconfig". An example result is shown below:

Further information can be displayed with an "ipconfig /all" command. Your programming device's adapter card type and Ethernet (MAC) address can be found here:

Dear Umencho,

Thank you for your reply.

I was able to navigate the webpage ofweb4txp client log in. I exactly know the user name and password of the client howeveri was not able to connect.
