SYSMAC CS-series Ethernet Unit
CS1W-ETN21
Organically Connect the Production
Site and Management
• Select the required communications services according to
application needs to flexibly integrate PLCs with an Ethernet
information network.
Features
•Use Ethernet to implement various communications protocols.
•Implement FINS message communications using UDP/IP or TCP/IP with a user application on a host computer or with Support Software, such
as the CX-Programmer.
•Use the clock on an SNTP server to automatically adjust the clocks in the PLCs connected to the Ethernetnetwork. (An SNTP server is required
separately.)
•An FTP server is built in, so files can be used to transfer PLC data between network PLCs and workstations or personal computers with an FTP
client.
•Email can be used to send commands to the PLCs, or triggers can be set so that the PLCs will send PLC data or Ethernet Unit status to a host
computer.
•The standard UDP/IP and TCP/IP protocols are supported to enable communications with a wide range of devices, workstations, personal
computers, and Ethernet modules from other manufacturers.
•The SMTP/POP3/SNTP servers enable the use of host names instead of IP addresses. (A DNS server is required separately.)

Upgrade Details
Web function added The unit settings and status monitoring for the Ethernet Unit can be
easily performed from a Web browser.
Function prohibiting access using FINS/
UDP from nodes with dynamically changed
IP addresses
Access to change the remote IP address from a node using FINS/UDP
can be prohibited (IP address protection).
Upgrade Details
ETN11-compatible mode added to the
ETN21 settings for FINS/UDP.
A mode compatible with the CS1W-ETN11/CJ1W-ETN11 was added in
the operating specifications for FINS/UDP messages sent from a
different UDP port number than the FINS/UDP port number set in the
Ethernet Unit.
Upgrade Details
CIDR function added to subnet mask
settings
Anoptionsettingwasadded tothesubnetmasksettings toenableCIDR.
Enabling CIDR allows you to use classless IP addresses in the subnet
mask setting.
High-speed option added for socket service
This option can be set to improve communications performance for the
socket service that is implemented by manipulating dedicated control
bits. The performance is the same as the previous version if this option
is not set.
Linger option added to socket options for
TCP open requests. A linger option can now be set in the options for passive or active TCP open requests.
