Basic System Configuration
An NX-series Controller supports the following two types of configurations.
• Basic Configuration
The basic configurations include the CPU Unit and the Configuration Units that are controlled directly
by the CPU Unit. There are two basic configurations.
a) EtherCAT network configuration
• Other Network Configurations
These are the configurations of the systems that are connected to the CPU Unit’s built-in EtherNet/IP
port and Communications Units.
z Basic Controller Configuration
With an NX-series CPU Unit, you can use an EtherCAT network as a basic system.
With the EtherCAT network system of the NX-series CPU Unit, the period for sequence processing
and motion processing in the CPU Unit is the same as the EtherCAT communications period.
This enables high-precision sequence control and motion control with a constant period and little
fluctuation.
For information on EtherCAT, refer to the NJ/NX-series CPU Unit Built-in EtherCAT Port User’s Manual (Cat. No. W505).
