Configure your Digital Module on an EtherNet/IP Network 87

Ownership

In a Logix5000 system, modules multicast data. This means that multiple

modules can receive the same data at the same time from a single module.

When you choose a communication format, you have to choose whether to

establish an owner or listen-only relationship with the module

If the module is also in the I/O configuration of another controller, then select

the Listen Only version of the Comm Format (for example, Listen Only -

Input Data).

Select a Remote Adapter

The remote adapter you use depends on the distributed I/O you use. When

using FLEX I/O modules, you use the FLEX I/O adapter, cat. no.

1794-AENT, which requires the BOOTP utility.

Owner controller The controller that creates the primary configuration and communication connection to a

module. The owner controller writes configuration data and can establish a connection to

the module.

Listen-only connection An I/O connection where another controller owns/provides the configuration data for the

I/O module. A controller using a listen-only connection only monitors the module. It does

not write configuration data and can only maintain a connection to the I/O module when

the owner controller is actively controlling the I/O module.

An owner connection is any connection that

does not include Listen-Only in its Comm Format.
