Unit Version Upgrade Information

28
The details of the upgrade to the Ethernet Unit version are as follows:
■ Unit Version 1.3
Upgrade
Web function added
Function prohibiting
access using FINS/
UDP from nodes
with dynamically
changed IP
addresses
■
Unit Version 1.4
Upgrade
ETN11-compatible
mode added to the
ETN21 settings for
FINS/UDP.
■ Unit Version 1.5
Upgrade
Added CIDR function
to subnet mask set-
tings.
Added option for
high-speed socket
services.
Added linger option
to socket options for
TCP open request.
Changed position of
node address set-
ting switches (CJ1W-
ETN21 only)
The unit settings and status monitoring for the Ethernet Unit
can be easily performed from a Web browser.
Access to change the remote IP address from a node using
FINS/UDP can be prohibited (IP address protection).
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.
An option setting has been added to the subnet mask settings
to enable CIDR. Enabling CIDR enables using the IP address
with classless subnet mask settings.
Enabling high-speed socket services improves the perfor-
mance of sending and receiving for socket services using spe-
cific bits. If high-speed socket services are disabled,
performance is the same as previously.
It is possible to specify the linger option in the option settings
for the TCP open request (both passive and active).
The position of the node address setting switches was
changed. The setting method and setting range are the same
as previously.
