Description
(A)
EtherCAT master
*1
The EtherCAT master manages the network, monitors the status of slaves,
and exchanges I/O data with slaves.
The High-speed Analog Input Units can be connected with the following OM-
RON master products.

They cannot be connected to other manufacturers’ master products, or other
OMRON master products.
(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
The Support Software runs on a personal computer and it is used to configure
the EtherCAT network and EtherCAT Slave Terminal, and to program, moni-
tor, and troubleshoot the Controllers.
(F)
ESI (EtherCAT Slave In-
formation) 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.

Example of Application System Configuration
The following figure shows an example of a characteristic inspection system configuration where an
NX-series High-speed Analog Input Unit is used.
The system reads analog input signals to detect abnormal noise, vibration and torque values through
the inspection, and determines whether the workpiece operation is acceptable or not.
It uses input from devices such as a photoelectric sensor as trigger input to efficiently obtain the ana-
log input data required for inspection.
In this way, you can configure a system based on a general-purpose Controller and perform character-
istics inspection without using special measuring equipment.
