2. Select the folder where you want to save the Relation List.
3. Enter a File name for the Relation List, for example, control system
configuration, and click Save.
You can leave the Save as type at the default setting: Bootp Config Files
(*.bpc).
You now have the option to open the file containing the Relation List at a
later session.
Use DHCP Software to
Configure Your Adapter DHCP (Dynamic Host Configuration Protocol) software automatically assigns
IP addresses to client stations logging onto a TCP/IP network.
DHCP is based on BootP and maintains some backward compatibility. The main
difference is that BootP was designed for manual configuration, while DHCP
allows for dynamic allocation of network addresses and configurations to newly
attached devices.
Be cautious about using DHCP software to configure your adapter. A DHCP
server typically assigns a finite lease time to the offered IP address.
When 50% of the leased time has expired, the adapter attempts to renew its IP
address with the DHCP server.
The possibility exists that the adapter will be assigned a different IP address,
which would cause the adapter to cease communicating with the ControlLogix
controller.
See Configure the Adapter with Fixed IP Address on page 45 to configure the
adapter with a fixed IP address.
Chapter Summary This chapter described the requirements and procedures for configuring the IP
address, subnet mask, and optional Gateway address.
ATTENTION: To avoid unintended control or loss of control, the I/O
adapter must be assigned a fixed IP address. A dynamically provided IP
address should be used only at initial configuration. If a DHCP server is
used, it must be configured to assign the same IP address to your adapter.
Failure to observe this precaution may result in unintended machine
motion or loss of process control.
