Overview
This function is used to read and set the Slave Terminal
parameters from the Sysmac Studio. You can make set-
tings offline, or go online and read and set the Unit con-
figuration of the actual Slave Terminal.
The EtherCAT Coupler Unit exchanges I/O data at a fixed
interval with the mounted NX Units. There are the follow-
ing two I/O exchange methods.
• Free-Run refreshing
• Synchronous I/O refreshing
This Unit can exchange I/O data even if NX Units that
support Free-Run refreshing are mounted together with
Units that support synchronous I/O refreshing.
The timing at which the EtherCAT Coupler Unit
exchanges I/O data with the mounted NX Units is asyn-
chronous with the timing at which the NX Units refresh
the data to be exchanged.
The timing at which the EtherCAT Coupler Unit
exchanges I/O data with NX Units that have the functions
listed below is synchronous with the timing at which the
NX Units refresh the data to be exchanged.
• Synchronous input refreshing
• Synchronous output refreshing
This function is used to register NX Units that are not
connected to the actual configuration but will be added at
a later time in the Unit configuration information as
unmounted Units. If you use this function, you do not
have to modify the user program after the NX Units are
added.
These are the unique functions of an EtherCAT slave as
a Sysmac device.
This function allows the EtherCAT Coupler Unit to use the
Sysmac error status, which is assignable to I/O data, to
notify the EtherCAT master when an error occurs. This
notification acts as a trigger that allows you to use the
troubleshooting functions on the Sysmac Studio to view
and correct errors that occur in the EtherCAT Slave Ter-
minal.
This function sets the node address on the Sysmac Stu-
dio.
This function verifies the EtherCAT network configuration
based on serial numbers.
The EtherCAT Coupler Unit checks the information in the
SII (Slave Information Interface).
