*1. A CPU Unit with unit version 1.05 or later is required to connect an EtherCAT Slave Terminal to the built-in
EtherCAT port on an OMRON NJ-series CPU Unit. Refer to A-7-2 Relationship between Unit Versions of
EtherCAT Coupler Unit and CPU Units on page A-59 for details. OMRON CJ1W-NC81/82 Position Control
Units cannot be connected to the EtherCAT Slave Terminal even though they support EtherCAT.
*2. Version 1.06 or higher of the Sysmac Studio is required to set up an EtherCAT Slave Terminal. Refer to A-7-1
Relationship between the Unit Versions of EtherCAT Coupler Unit and Sysmac Studio Versions on page A-59
for details.
NX-series EtherCAT Coupler Unit User's Manual (W519)
The EtherCAT master manages the EtherCAT network, monitors the status of the
*1
slaves, and exchanges I/O data with the slaves.
The EtherCAT Coupler Unit is an interface that performs process data communi-
cations between a group of NX Units and the EtherCAT master over an EtherCAT
network.
The I/O data for the NX Units is first accumulated in the EtherCAT Coupler Unit
and then all of the data is exchanged with the EtherCAT master at the same time.
The EtherCAT Coupler Unit can also perform message communications (SDO
communications) with the EtherCAT master.
You can connect up to 63 NX Units.
The NX Units perform I/O processing with connected external devices. The NX
Units perform process data communications with the EtherCAT master through
the EtherCAT Coupler Unit.
Refer to 2-2-2 Types of NX Units on page 2-6 for the types of NX Units.
The End Cover is attached to the end of the Slave Terminal.
The Sysmac Studio runs on a personal computer and it is used to configure the
EtherCAT network and EtherCAT Slave Terminals, and to perform programming,
*2
monitoring, and troubleshooting.
You can connect the computer in which the Sysmac Studio is installed to the
peripheral USB port or built-in EtherNet/IP port on an NJ-series CPU Unit. Or you
can connect it to the peripheral USB port on the EtherCAT Coupler Unit to set up
the EtherCAT Slave Terminal.
Refer to 2-3 Support Software on page 2-7 for the connection procedure.
The ESI file contains information that is unique to the EtherCAT Slave Terminal in
XML format. You can load the ESI file into the Sysmac Studio to easily allocate
Slave Terminal process data and make other settings.
The ESI files for OMRON EtherCAT slaves are already installed in the Sysmac
Studio. You can update the Sysmac Studio to get the ESI files for the most recent
models.
Use a double-shielded cable with aluminum tape and braiding of category 5
(100BASE-TX) or higher, and use straight wiring.
