Set the Network IP Address
The IP address uniquely identifies the module. The IP address is in the form
xxx.xxx.xxx.xxx where each xxx is a number from 000…254.
There are some reserved values that you cannot use as the first octet in the
address. These numbers are examples of values you cannot use:
• 001.xxx.xxx.xxx
• 127.xxx.xxx.xxx
• 223 to 255.xxx.xxx.xxx
The specific reserved values that cannot be used vary by application.
For more information about how to configure an EtherNet/IP network, see
EtherNet/IP Network Configuration User Manual, publication ENET-UM001
.
Depending on the 1756 EtherNet/IP communication module, you can use some
or all of these tools to set the network Internet Protocol (IP) address:
• Rotary switches - The 1756-ENBT and 1756-EWEB modules do not offer
rotary switches. If you are using either of these modules, skip Set the
Network IP Address with the Rotary Switches on page 46
and go to Set
the Network IP Address with the BOOTP/DHCP Server on page 47
.
• Bootstrap Protocol (BOOTP)/Dynamic Host Configuration Protocol
(DHCP) server
• RSLinx® Classic software
• Studio 5000 environment
The module uses these tools sequentially to set the IP address.
