Set the Network IP Address Chapter 4
The New Entry dialog box appears.
7. Type an IP Address, Hostname, and Description for the module.
8. Click OK.
9. To assign this configuration permanently to the module, wait for the
module to appear in the Relation List panel and select it.
10. Click Disable BOOTP/DHCP.
When power is recycled, the module uses the assigned configuration and
does not issue a BOOTP request.
Use DHCP Software
Dynamic Host Configuration Protocol (DHCP) software automatically assigns
IP addresses to client stations logging on to a TCP/IP network. DHCP is based
on BOOTP and maintains some backward compatibility. The main difference is
that BOOTP allows for manual configuration (static), while DHCP allows for
both static and dynamic allocation of network addresses and configurations to
newly attached modules.
Be cautious when using DHCP software to configure a module. A BOOTP
client, such as the EtherNet/IP communication modules, can start from a DHCP
server only if the DHCP server is written to handle BOOTP queries. This is
specific to the DHCP software package used. Consult your system administrator
If you do not click Disable BOOTP/DHCP, on a power cycle, the host
controller clears the current IP configuration and begins sending
BOOTP requests again.
