Wide-ranging Control
Capability Using Ethernet
Capability Using Ethernet
The Ethernet Unit enables a Programmable Controller (PC) to support a wide
range of protocols via Ethernet, including data communications by TCP/IP
and UDP/IP socket services, FINS command execution (OMRON’s standard
protocol), FTP file transfers, and SMTP message communications.

Communications by UDP/
IP and TCP/IP
IP and TCP/IP
The Ethernet Unit supports the standard Ethernet protocols, UDP/IP and
TCP/IP, so it can communicate with other Ethernet devices, workstations, per-
sonal computers, and Ethernet Units produced by other manufacturers. It can
utilize up to eight socket ports for the various protocols, allowing it to be
employed in a wide range of applications.

Easy Use of Socket
Services
Services
TCP or UDP socket services can be easily accessed either by executing the
CMND(490) instruction or by presetting parameters and then manipulating
dedicated control switches in memory. Presetting parameters eliminates the
need for ladder programs to monitor the completion timing of instructions and
socket service processing, and thereby reduces the work hours involved in
program development.

The Ethernet Unit also supports FINS message communications, OMRON’s
standard communications service, so other OMRON PCs can be accessed by
using SEND(090), RECV(098), and CMND(490) instructions in ladder pro-
grams. In addition, the FINS gateway function can be used to allow access to
other PCs on not only the same Ethernet network but also on other networks
such as Controller Link and SYSMAC Link.

File Transfers Between PC
and Host Computer
(FTP Server Function)
and Host Computer
(FTP Server Function)
The Ethernet Unit has a built-in FTP server function, so any workstation or
personal computer with an FTP client function can be used for reading files
from or writing files to the PC. This enables large amounts of data to be trans-
ferred at one time without any need for writing a ladder program.

E-mail Capability
User-defined messages, Unit error information, status information, and so on,
can be sent from the PC to the mail server as e-mail. This function allows
information generated at the production site to be sent out as e-mail.

24-VDC Power Supply for
Transceiver
Transceiver
For the CS1W-ETN01 (10Base-5), a 24-VDC power supply can be used as
the power supply for the transceiver. The Ethernet Unit voltage output pro-
vides for a voltage drop in the transceiver cables, so there is no need to adjust
the power supply voltage.

Controller Link Network
Connection
Connection
Ethernet, the information-system network, can be connected to Controller
Link, the control-system network, using the FINS communications service.
This allows a PC on the Controller Link network to be monitored from a PC on
the Ethernet network, and, conversely, for data to be exchanged between a
PC on the Controller Link network and a PC on the Ethernet network.
