EtherNet/IP – Start-up 149
Configuring the client
After the adapter module has been initialized by the drive, you
must prepare the client for communication with the module. An
example of an Allen-Bradley® PLC is given below. If you are using
another client system, refer to its documentation for more
information.
The example applies to all drive types compatible with the module.

Before you start
Decide on these points before you start the client configuration.
Select protocol/profile
During the configuration of the drive and the client, it is necessary
to select a communication protocol, in this case EtherNet/IP, and a
communication profile. The communication profile determines
which I/O assemblies and objects are available. See chapter
EtherNet/IP – Communication profiles for more information.
Select output and input assembly instances
EtherNet/IP devices implement multiple objects each with many
attributes. While it is possible to write or read each attribute
separately to control the drive, this is inefficient. Assembly object
instances provide a means to group writes or reads of attributes.
The selection of assembly objects is limited by the choice of the
communication profile. This table gives a listing of the output and
input assemblies.
