Changing the Password
The default FTP password is “system”. You can change the FTP password via a parameter in the AUP file, which
is stored to the PLC via the programmer, or by using the Station Manager.
Changing the Password from the Advanced User Parameters File
The following line should be added to the AUP file to change the FTP password (for example, to “my_ftp_pw”):
tpassword = my_ftp_pw
Changing the Password from the Station Manager
In addition, you can change the FTP password (for example to “my_ftp_pw”) using the following Station
Manager command:
= CHPARM tpassword my_ftp_pw
The FTP password can be up to 10 characters long and uses the same character set listed for the reference
viewer password described later in this document. These passwords are not case sensitive.
Arguments for Station Manager CHPARM command must be enclosed in double quotes to preserve the
capitalization of the argument. However since these passwords are case insensitive, the double quotes are not
required.
Note: The CHPARM command is not available if the PLC has received a valid configuration from the
Programmer.
Web Page File Transfer
After logging into the PLC’s FTP server, web page files can be copied from the PC to the PLC through the
following steps:
1.
Set the FTP file transfer type to binary by typing in “binary”
2. For each file, change to the desired directory if appropriate by typing “cd ./subdirectory”. Then transfer the
file using the “put” command by typing: “put filename.htm”
3. Verify all files are properly transferred by typing in: “dir” or “ls”. This returns a list of the files located at the
current directory on the PLC Ethernet Interface
4. Quit the FTP session by typing in “quit” or “bye”.
If you copy a file that already exists in the module, the new file overwrites the existing file without warning. One
of the files stored will be a fault string file that will be specific for each language supported.
The PLC FTP server also supports the following standard FTP commands:
▪
“get” command - allows the user to transfer files from the PLC web server to their local PC (for example
“get filename1.htm”).
▪
“delete” command – allows user to delete web pages from the server (for example “delete filename1.htm”).
