DHCP is the default setting, and a DHCP server is required to assign the
module its initial IP address. Note that the RSLogix 5000 DHCP Server tool
can be used to set the IP address.
‡
Static IP Address - select this option to use the same IP address every time it
powers up.
If you enter an IP address that is already in use and reboot the module, you
will not be able to access the module through the web interface. To repair this,
access the module through the Add on Profile (AOP) and reset the network
configuration. Please see the AOP documentation for further information.
„
IP Address - the module’s IP address. Be sure the IP address you use is not
assigned to another device in your network.
This field is enabled when you select Static IP Address.
„
MAC Address - the module’s Media Access Control (MAC) address. (This comes
from the module and cannot be changed.)
„
Subnet Mask - the module’s subnet mask.
This field is enabled when you select Static IP Address. This value will be unique
to your location. Check with your IT department to get the correct value.
„
Default Gateway - the network default gateway. This allows data to be passed
from one subnet to another subnet in a network.
This field is enabled when you select Static IP Address.
„
Search Domain - the DNS search domain.
This field is enabled when you select Static IP Address.
„
Primary DNS Server - the first Domain Name System (DNS) server.
This field is enabled when you select Static IP Address.
„
Secondary DNS Server - the second DNS server.
This field is enabled when you select Static IP Address.(optional)
If you change the default IP address configuration from DHCP to Static IP
Address, or if you use BootP through an RSLogix and a BOOTP/DHCP server,
you cannot access the module using its host name. The new IP address is not
associated with the module host name on the DNS server and the host name
does not resolve. To avoid this issue, consult your local IT department to
register the new IP address with the DNS server.
