Section 2 provides an overview of the communications functions that can be used with the Ethernet
Unit.
Section 3 explains how to install the Ethernet Unit and make the initial settings required for operation.
Section 4 explains the system setup and the words allocated in the CIO Area and the DM Area for
Ethernet Unit operations.
Section 5 provides information on communicating on Ethernet networks 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 PC are sent via the SEND(090),
RECV(098), and CMND(490) instructions programmed into the user ladder-diagram program. Refer to
the CS/CJ-series CS1G/H-CPU@@
-E, CJ1G-CPU@@ Programmable Controllers Instruction Refer-
ence Manual (W340) for further details on programming these instructions.
Section 6 describes the functionality provided by the Ethernet Unit via the socket services.
Section 7 describes the functions provided by the FTP server.
Section 8 explains the Ethernet Unit’s mail function.
Section 9 describes functions that allow you to test communications.
Section 10 describes information and procedures that can be used to troubleshoot problems that
sometimes occur with Ethernet Unit and Ethernet communications.
Section 11 describes the FINS commands that can be sent to an Ethernet Unit and the responses that
