Item Description
(A)
EtherCAT master
*1
*1. An EtherCAT Slave Terminal cannot be connected to any of the OMRON CJ1W-NC81/82 Position Control
Units even though they can operate as EtherCAT masters.
The EtherCAT master manages the network, monitors the status of slaves,
and exchanges I/O data with slaves.
(B) EtherCAT Coupler Unit The EtherCAT Coupler Unit serves as an interface for process data communi-
cations on the EtherCAT network between the NX Units and the EtherCAT
master.
The I/O data for the NX Units is 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.
(C) NX Units The NX Units perform I/O processing with connected external devices.
The NX Units perform process data communications with the EtherCAT mas-
ter through the EtherCAT Coupler Unit.
(D) End Cover The End Cover is attached to the end of the Slave Terminal.
(E)
Support Software
*2 *3
*2. The term Support Software indicates software that is provided by OMRON. If you connect to a master from
another company, use the software tool corresponding to that master.
*3. Refer to 1-5 Support Software on page 1-14 for information on Support Software.
The Support Software runs on a personal computer and it is used to configure
the EtherCAT network and EtherCAT Slave Terminal, and to program, monitor,
and troubleshoot the Controllers.
(F) ESI (EtherCAT Slave
Information) file
The ESI file contains information that is unique to the EtherCAT Slave Termi-
nal in XML format. You can load an ESI file into the Support Software to easily
allocate Slave Terminal process data and make other settings.
The ESI files for OMRON EtherCAT slaves are installed in the Support Soft-
ware. You can obtain the ESI files for the latest models through the Support
Software’s automatic update function.
(G) Communications cable Use a double-shielded cable with aluminum tape and braiding of Ethernet cat-
egory 5 (100Base-TX) or higher, and use straight wiring.
