2-1 Features of the PROFINET Coupler
Unit
A PROFINET Coupler Unit is the connecting unit between a PROFINET IO Controller and a group of
NX Units.
The NX Units can be flexibly combined with a PROFINET Coupler Unit to achieve the optimum Profinet
IO Device for the application with less wiring, less work, and less space.
The features of the PROFINET Coupler Unit described below.
Cyclic I/O data exchange is used to exchange I/O data between the PROFINET IO Controller and NX
IO Units through the PROFINET Coupler Unit. In addition to I/O data, status information in the PROF-
INET Coupler Unit can be accessed from the PROFINET IO Controller Unit.
Various, general-purpose Ethernet devices can be used within the same PROFINET network because
PROFINET uses standard Ethernet technology.
The PROFINET Coupler Unit is equipped with two Ethernet ports that support the layer 2 Ethernet
switch functions.
This enables you to configure, in addition to star and tree topologies, a line topology without using
Ethernet switches.
