8 CIP Message Communications
8-5-4
TCP/IP Interface Object (Class ID: F5 hex)
This object is used to read and write settings such as the IP address, subnet mask, and default gate-
way. For an NX701 CPU Unit and an NX102 CPU Unit, it is necessary to use the route path of the CIP
communications command (the RoutePath in-out variable) to specify the port number (1 or 2) of the
built-in EtherNet/IP port to access.

is executed, the general status "0C hex" (Object State Conflict) is
returned.
