FINS Commands Addressed to EtherNet/IP Units or Built-in EtherNet/IP Ports Appendix E
Precautions
• No response will be returned if the command ends normally. A response will be returned only if an error
occurs.
• In some cases, send requests (SEND(192)/RECV(193) instructions) made from the PLC to the EtherNet/
IP Unit or built-in EtherNet/IP port just before execution of the RESET command may not be executed.
• Applications that use TCP/IP, such as FINS/TCP communications services, are closed immediately before
resetting.
Response Codes
CONTROLLER DATA READ
Reads the following data from the EtherNet/IP Unit or built-in EtherNet/IP port: Model number, version, IP
address, subnet mask, FINS UDP port number, mode settings, Ethernet address.

Response Block
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).
Example Model: CS1W-EIP21, CJ1W-EIP21, CJ2B-EIP21, or CJ2M-EIP21
Example Version: V2.00
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.
