Parameters
Model number, Version (Response)
The model number and version of the EtherNet/IP Unit or built-in EtherNet/IP port are returned as ASCII char-
acters occupying 20 bytes each (i.e., 20 characters each). If all bytes are not used, the remaining bytes will be
all spaces (ASCII 20 Hex).
By convention, the model number of the built-in EtherNet/IP port on a CJ2H-CPU@@-EIP CPU Unit is CJ2B-
EIP21.
By convention, the model number of the built-in EtherNet/IP port on a CJ2M-CPU3@ CPU Unit is CJ2M-EIP21.
IP Address, Subnet Mask (Response)
The IP address and subnet mask of the EtherNet/IP Unit or built-in EtherNet/IP port are returned as 4 bytes
each.
FINS UDP Port Number (Response)
The UDP port number of the EtherNet/IP Unit or built-in EtherNet/IP port for FINS is returned as 2 bytes.
