NJ/NX-series CPU Unit Built-in EtherNet/IP Port User’s Manual (W506)
Variable name _EIP1_EtnOnlineSta
Meaning Port1 Online Global/local Global
Function 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.
Note You can use this system-defined variable only for NX-series CPU Units.
Data type BOOL Range of values TRUE or FALSE
