FTP Server Function Details Section 11-2
11-2-2 Connecting to the FTP Server
The host computer must connect to the FTP server before the FTP server
functions can be used. The login name and password set in the Unit Setup will
be used when connecting. The default FTP login name is “CONFIDENTIAL”
and no password is required.
The FTP server in the EtherNet/IP Unit or built-in EtherNet/IP port can con-
nect to only one client at a time. If a client attempts to connect when the FTP
server is in use, a message will be returned and connection will be refused.
Note When general-purpose FTP software is used, files can be transferred and
read using a graphical user interface similar to Explorer.
Login Name and Password Setting
The default login name for FTP is “CONFIDENTIAL” and no password is set
for the default login, so login is possible by simply entering “CONFIDENTIAL”
as the login name. A user-set login name and password can also be set in the
User Setup (CPU Bus Unit System Setup).
Login Messages
Setting Restrictions
The following restrictions apply to login names and passwords.
• The login name and password must consist of alphanumeric characters,
hyphens, and/or underscores. They are not case sensitive.
• A login name consists of 12 characters.
• A password consists of 8 characters.
• Always set a password when setting a new login name. The login name
will not be valid unless a password is set for it.
• If a login name is not set or contains illegal characters, the default login
name, CONFIDENTIAL, must be used. No password is required and any
password that is set will be ignored.
FTP File Transfer Mode
FTP has two file transfer modes: ASCII mode and binary mode. Before start-
ing to transfer files, use the type command (specifies the data type of trans-
ferred files) to select the required mode.
Always select binary mode for binary files (extensions .IOM, .STD, or .OBJ) in
the CS/CJ-series file memory and other program files (with extensions such
as .CXP).
