Precautions for Correct Use
There are functional restrictions when you connect to the EtherCAT Coupler Unit via the USB
port in comparison with connecting to the NJ/NX-series CPU Unit. We therefore recommend
that you connect to the NJ/NX-series CPU Unit.
The functions that you can use on the Sysmac Studio depend on what the Sysmac Studio is connected
to. Refer to the NX-series EtherCAT Coupler Unit User’s Manual (Cat. No. W519) for details.
Connect the Sysmac Studio to the USB port on the EtherNet/IP Coupler Unit.
This connection allows you to download, upload, and monitor the safety programs for only the Safety
CPU Unit and Safety I/O Units that are under the EtherNet/IP Coupler Unit that the Sysmac Studio is
online with. The other devices cannot be accessed.
