On Win7
To see the IP address
Start> "cmd.exe" :: This will open a "DOS Command Window"
"ipconfig" :: This will display ALL your IP addresses on your box. You have to find the one for your connection.
To change the IP address
Start > Control Panel > Network and Sharing Center > Local Area Connection > Properties
[Scroll down and highlight "Internet Protocol Version 4 (TCP/IPv4)"] > Properties
For normal connections check the radio buttons that say "
Obtain an IP address automatically" and "
Obtain a DNS server address automatically"
For machine tool connections such as HMIs that use static addresses on a private subnet
1) You need to know the IP address ranges of the devices: Commonly 192.168.y.2 to 192.168.y.20 where y is a number from 0 to 255
2) You need to pick an IP address that matches the first three "octets" you found 192.168.y and then pick the fourth octet to be different than any of the others in the range of 2 to 250.
ex: Devices are 192.168.5.8, 192.168.5.9, 192.168.5.7 then your box needs to be 192.168.5.z where z can be 10 to 250 or 2 to 6 such as 192.168.5.100
3) Select "
Use the following IP address" and set the chose IP; also in the subnet mask row put 255.255.255.0; leave the other rows alone.
4) Close everything and "Repair" the connection or reboot the laptop. You can then verify the IP address change as above.
Warning: The "Alternate Connection" tab was supposed to be usable. It is in XP3 but fails in Win7. Do not use.
Warning: Remember to set it back when done to obtaining addresses automatically if you need to make internet connections later.
