3 System-defined Variables Related to the Built-in EtherNet/IP Port
3-1 System-defined Variables Related to
the Built-in EtherNet/IP Port
You can use the system-defined variables that are provided for the built-in EtherNet/IP port in programs
to check the status of the built-in EtherNet/IP port.
Checking for Errors in the Built-in EtherNet/IP Port
You can check for built-in EtherNet/IP port errors, Sysmac Studio setting errors, Network Configura-
tor setting errors, TCP/IP application errors (e.g., FTP or NTP), etc. The following hierarchy is used.
The system gives the error status at each level by logically ORing the error status information in the
next lower level.
