Function NX-series CPU Units: Indicates that the built-in EtherNet/IP port’s communications can be used via the communications
port 1 (that is, the link is ON, IP address is defined, and there are no errors).
TRUE: The built-in EtherNet/IP port’s communications can be used.
FALSE: The built-in EtherNet/IP port’s communications is disabled due to an error in initial processing, restart pro-
cessing, or link OFF status.
