Description
A CPU Unit to which the NX-series EtherNet/IP
Unit is connected. This Unit performs machine
control and process control of the system.
One of X Bus Units which performs EtherNet/IP
communications.
An interface Unit to connect an NX-series CPU
Unit to control devices such as sensors and ac-
tuators. This Unit can also be connected to an
NX-series Communications Coupler Unit.
A CPU Unit which controls the safety circuit of
manufacturing equipment. This Unit controls
both of the safety control within equipment by
FSoE and the line safety control by CIP Safety.
