IP ADDRESS READ

Reads the local IP address and subnet mask in the CPU Bus Unit System Setup and the FINS node address.
The values read with this command, however, are not necessarily the settings actually used for operation. The
settings that are actually used for operation can be confirmed using CONTROLLER DATA READ (page 392)
and ADDRESS INFORMATION READ (page 414).
This command is supported for CJ-series EtherNet/IP Units only.
