Configure your Digital Module on an
EtherNet/IP Network
How to Use This Chapter
This chapter describes how a controller controls distributed I/O over an
EtherNet/IP network. The controller requires a communication module to
connect to the network. Distributed I/O modules require an adapter to connect
to the network.
In this example, we show you how to control FLEX I/O over Ethernet using
RSNetWorx for Ethernet and RSLogix 5000 software.
To control distributed I/O over Ethernet, you must:
• Add local and remote Ethernet communication modules to your
RSLogix 5000 project.
• Add distributed I/O to your RSLogix 5000 project.
• Schedule the Ethernet network via RSNetWorxRSNetWorx for Ethernet.
• Use the I/O information in RSLogix 5000 software.
You can also validate connections to distributed I/O when controlling it over
Ethernet. This task is useful when one or more of the connections are not
