Immediate Remote Access to PLCs Via
Ethernet
Improved FINS Message Communications
• Conforms to TCP/IP.
• Increased number of nodes. (Previously 126 nodes max. in-
creased to 254 nodes max.)
• Communications are still possible even if IP address of host
computer changes.
• Multiple FINS applications can be connected online in the per-
sonal computer.
• FINS message communications response is up to four times
faster than previous models.
Improved Mail
• Mail can be sent containing commands to the PLC (e.g., mail
can be used to read I/O memory in the CPU Unit and send com-
mands to backup memory).
• Files can sent as mail attachments (a data file can be automat-
ically generated and sent as an attachment when specified con-
ditions are met).
• More advanced mail send conditions (e.g., sending mail when
values in the CPU Unit’s I/O memory change to specified val-
ues)

Specify Host Name for Server (DNS Client Function)
Automatically Adjusted Built-in Clock (SNTP Client
Function)
FTP Server Function, and Socket Services Are Also
Supported (Same as Previous 10-Mbps Ethernet Unit)
Mail, DNS client, SNTP client, FTP server, and socket service are
not supported for the CS1D-ETN21D.
