Assigning an IP address to a CPU online
You can assign an IP address to a network device online. This is particularly useful in an
initial device configuration.
1. In the "Project tree," verify that
no IP address is assigned to the
CPU, with the following menu
selections:
• "Online access"
• <Adapter card for the network
in which the device is located>
• "Update accessible devices"
NOTE: If STEP 7 displays a MAC
address instead of an IP address,
then no IP address has been
assigned.
2. Under the required accessible
device, double-click "Online &
diagnostics".
3. In the "Online & diagnostics"
dialog, make the following menu
selections:
• "Functions"
• "Assign IP address"
