NX-series EtherCAT Coupler Unit User's Manual (W519)
Item
Set up the Slave Terminal (create the configuration and set
the parameters) on the Edit Slave Terminal Configuration Tab
Page on the Sysmac Studio.
Create the Unit configuration information of the Slave Termi-
nal (EtherCAT Coupler Unit and NX Units) offline.
Make the I/O allocations for the EtherCAT Coupler Unit and
NX Units as required.
Make the Unit operation settings for the EtherCAT Coupler
Unit and NX Units as required.
Create the Unit application data. (This step applies only to
Units that have Unit application data.)
Set the EtherCAT master parameters (process data commu-
nications cycle, wait time for slave startup, etc.). The values
that are set are reflected in the network configuration infor-
mation.
To enable access in the user program in the NJ-series CPU
Unit, the I/O data that is assigned in the I/O allocation infor-
mation is assigned to device variables and axis variables.
If necessary, change the names of automatically generated
device variables for each I/O port to user-defined variable
names.
If you will control Position Interface Units with the Motion
Control Function Module, create the axes and assign I/O
data to the axis variables.
Write the user program with device variables and axis vari-
ables.
Make the task settings. If you will use synchronous I/O
refreshing in DC Mode to refresh I/O for EtherCAT Slave Ter-
minals, set the task period of the primary periodic task so that
it is longer than the refresh cycle of the NX bus.
