Chapter 2 Install a 1768 EtherNet/IP Communication Module
Grounding Considerations
Set the Network IP Address To operate an EtherNet/IP communication module on an EtherNet/IP network,
you must set a 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 configuring an EtherNet/IP network, see
EtherNet/IP Network Configuration User Manual, publication
ENET-UM001 .
You can use these tools to set the network Internet Protocol (IP) address on your
1768 EtherNet/IP communication module:
• Bootstrap Protocol (BOOTP)/Dynamic Host Configuration Protocol
(DHCP) server
• RSLinx Classic software
• the Studio 5000 environemnt
The module uses these tools sequentially to set the IP address.
The 1768 EtherNet/IP communication modules are shipped with BOOTP/
DHCP enabled.
ATTENTION: This product is grounded through the DIN rail to chassis ground.
Use zinc-plated yellow-chromate steel DIN rail to assure proper grounding. The
use of other DIN rail materials (for example, aluminum or plastic) that can
corrode, oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.87 in.) and use end-anchors appropriately.
