NJ-series CPU Unit Built-in EtherNet/IP Port User’s Manual (W506)
User-specified CIP commands can be sent to devices on the EtherNet/IP network. CIP commands,
such as those for reading and writing data, can be sent and their responses received by executing the
CIP Send instruction from the user program in the NJ-series CPU Unit (without a connection).
You set the built-in EtherNet/IP port in the BOOTP settings to use the BOOTP client to obtain settings,
such as the built-in EtherNet/IP port IP address.
