This section provides information on communicating on Ethernet Systems and interconnected networks using FINS
commands. The information provided in the section deals only with FINS communications in reference to Ethernet Units.
FINS commands issued from a PLC are sent via the SEND(090), RECV(098), and CMND(490) instructions programmed
into the user ladder-diagram program. Although an outline of these instructions is provided in this section, refer to the CS/
CJ-series Programmable Controllers Programming Manual (W340) for further details on programming these instructions.
