Features of EtherCAT Slave Termi-
nals
An EtherCAT Slave Terminal is a building-block EtherCAT slave that is created by mounting a group of
NX Units to an EtherCAT Coupler Unit.
The NX Units can be flexibly combined with an EtherCAT Coupler Unit to achieve the optimum Ether-
CAT slave for the application with less wiring, less work, and less space.
The features of the EtherCAT Slave Terminals are described below.
The EtherCAT Coupler Unit is designed with the same communications and user interface specifica-
tions as other Sysmac devices. This provides optimum functionality and ease of operation when
used together with NJ-series Machine Automation Controllers and the Sysmac Studio Automation
Software.
When the EtherCAT Coupler Unit is used together with NX Units that support synchronous I/O
refreshing, all I/O refreshing is synchronized with the task period of the primary period of the
NJ-series CPU Unit. This provides an even higher level of synchronized control accuracy because it
suppresses jitter in the I/O response of the overall system.
This allows you to achieve the following control performance.
• Multiple Digital Input Units that support synchronous input refreshing process their inputs simulta-
neously, which improves the control accuracy of the system.
• Multiple Digital Output Units that support synchronous output refreshing process their outputs
simultaneously. This allows the outputs to refresh output devices in multiple locations at the same
time.
Optimum Functionality and Ease of Operation Based on Unified
Specifications
The Entire System Provides Extremely Accurate Synchronized Con-
