Product
CPU Bus Module
Compatible with 100Base-TX (100 Mbps) and 10
Base-T (10 Mbps)
254 total nodes possible
SNTP client functionality for automatic clock adjustment
DNS client functionality to specify servers by host name
Compatible with earlier CS1/CJ1 Ethernet modules
Transmit e-mail attachments from the Ethernet module
using an SMTP server to acquire user-created data,
error log data, and module status data.
Using a POP3 server, the user can send commands to
the Ethernet unit via e-mail.
Host computers that acquire a dynamic IP address (us-
ing DHCP) can send commands to the PLC and receive
responses.
Multiple FINS supported applications within the comput-
er can go on-line simultaneously.
Using FINS communications, both TCP/IP and UDP/IP
are supported.
Using the built-in FTP server, files can be read from or
written to the mounted memory card.
Using FINS communications, connectivity with devices
on other networks is possible (renting services).
Socket services (TCP or UDP protocols) allow for
Ethernet connected devices to send and receive data.
FINS commands can be sent or received by PLCs or
computers on the same Ethernet network.
Communications services
FINS communications, FTP server, socket services,
DNS client, Mail services, SNTP services.
Industrial Networking and Communications
J Ethernet Network
Take advantage of a wide range of communications capa-
bilities. Communicate with PLCs remotely through the Inter-
net or locally through an Ethernet network. Transfer data
with TCP/IP or UDP/IP socket services, execute Omron’s
standard FINS commands, transfer and receive memory
card files with FTP, send e-mail with SMTP or receive e-
mail with POP3. Select the communications services that
are required and flexibly connect PLCs on an Information-
Level Ethernet network.
Omron’s Ethernet modules support the full TCP/IP model
for maximum flexibility in data exchange. Omron uses
easy-to-establish routing tables to share common data
table contents instead of programming requests to share
specific blocks of data with specific PLCs. With Omron, all
communication modules can share data within PLC
memory. This allows great flexibility for future control modi-
fications without substantial reprogramming effort.
