_EIP_EtnOnlineSta Online NX-series CPU Units: Indicates that the
built-in EtherNet/IP port's communica-
tions can be used via the communica-
tions port 1 (that is, the link is ON, IP ad-
dress 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 er-
ror in initial processing, restart process-
ing, or link OFF status.
NJ-series CPU Units: Indicates that the
built-in EtherNet/IP port's communica-
tions can be used via the communica-
tions port (that is, the link is ON and IP
address is defined, and there are no er-
rors.)
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 er-
ror in initial processing, restart process-
ing, or link OFF status.
