SECTION 5
FINS Communications
This section provides information on communicating on Ethernet Systems and interconnected networks using FINS com-
mands. The information provided in the section deals only with FINS communications in reference to Ethernet Units.
FINS commands issued from a PC 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 CS1-series
CS1G/H-CPUjj-E Programmable Controllers Programming Manual (W340) for further details on programming these
instructions.
