Some functions that were added or changed for each model addition and unit version of the Communi-
cations Coupler Units are restricted depending on the models of the NX Units and unit versions.
The following is a list of restrictions on NX Units for the functions.
When you use the functions of the Communications Coupler Units shown below in the NX Units, use
the NX Units with the unit versions or the later unit versions shown in the models of the NX Units and
unit versions.
Note that the following tables do not show whether your NX Unit can be connected to the
Communications Coupler Unit. Refer to A-6-1 Connection to an EtherCAT Coupler Unit on page A-28
and A-6-2 Connection to an EtherNet/IP Coupler Unit on page A-35 for the connection specifications.
Also, refer to the user's manual for the Communications Coupler Unit for details on the functions listed
below.
The following is a list of restrictions for NX Units categorized by type.
