82 Configure your Digital Module on an EtherNet/IP Network

are not working but is not required, especially when all connections appear to

work normally.

When you first install a Rockwell Automation EtherNet/IP module (right out

of the box), the module is BOOTP/DHCP enabled.

Set Up the Hardware

In this example, the Logix5000 controller has an EtherNet/IP communication

module to connect to the EtherNet/IP network. The distributed (remote) I/O

has an EtherNet/IP adapter to connect it to the EtherNet/IP network.

The Logix5000 controller can communicate with each I/O module directly

(direct connection). Or you can configure a rack-optimized connection to the

EtherNet/IP adapter to send data to any digital I/O modules.

Make sure:

• the IP addresses are set for each EtherNet/IP module

• all wiring and cabling is properly connected

• the communication driver (such as, AB-ETHIP-1) is configured for the

programming workstation

For more information on the Ethernet Adapter and Flex I/O in an Ethernet

network, refer to publication ENET-UM001

Select a Requested Packet

Interval (RPI)

When you configure an I/O module, you define the requested packet interval

(RPI) rate for the module.

The RPI specifies the period at which data updates over a connection. For

example, an input module sends data to a controller at the RPI that you assign

to the module. Configure the RPI in milliseconds.
