Features
The following functions have been improved over previous Ethernet Unit mod-
els. They allow the scale of the system to be increased, and can give greater
flexibility to the system configuration including the host computer.
A built-in FTP server function enables data files in the PLC to be read from a
workstation or computer with an FTP client function, and for data to be written
to the PLC. Large amounts of data can be transferred at a time from clients,
without requiring ladder programming.
With previous Ethernet Unit models (CS1W-ETN01/CS1W-ETN11/CJ1W-
ETN11), e-mail could sent only from the Ethernet Unit, and the data that could
be sent was limited to user-created ASCII text data and system data. Now the
following e-mail functions have been added.
Commands for the PLC (mail remote commands) can be written into e-mail,
and the Ethernet Unit can receive them, execute them, and send responses
by e-mail.
This function can be linked to the CS/CJ File Memory function.
