10-1-1 Introduction
You can use the NJ-series System to build the communications system shown below.
*1 Use an EtherNet/IP Unit with unit version 2.1 or later. Also use a CPU Unit with unit version 1.01 or later and
Sysmac Studio version 1.02 or higher. Refer to A-12 Version Information for information on upgrades.
*2 To perform troubleshooting from an NS-series PT, connect the PT to the built-in EtherNet/IP port on the CPU
Unit.

Connection Connection method
Sysmac Studio connection Use USB or the built-in EtherNet/IP
port.
Connections between Controllers Connections with NJ-series Control-
ler or CJ2 CPU Unit
Use the built-in EtherNet/IP port or
a port on an EtherNet/IP Unit
*1
Connections between Controllers
and slaves
Connections to Servo Drives and
general-purpose slaves
Use the built-in EtherCAT port.
I/O controls Mount a DeviceNet Unit and use
