19 Network Functions in the Operator
Panel
This chapter describes operation of the functions for the FTP server, SMTP client,
operator panel applet and Web server function in the operator panel. Not available
for E1012 and E1022. For further information about the different functions, please
see the chapter Network Communication.
19.1 FTP Server
FTP (File Transport Protocol), a standard Internet protocol, is the easiest way of ex-
changing files between computers on the Internet. FTP is an application protocol
which uses the Internet’s TCP/IP protocols. FTP is normally used to transfer web
pages from their creators to the server where everybody on the Internet can access
them. It is also suitable for downloading programs and other files from another server
(operator panel) to your own computer.
When the operator panel functions as an FTP server it is possible to upload/down-
load files to/from the operator panel. To upload/download files, an FTP client
program is required in the PC, e.g. HMI Tools, Internet Explorer, Windows Com-
mander or some other standard FTP program.
Some libraries show files with a length of 0. This means that the file contains dynam-
ic data, i.e. the size of the file changes. This also means that even if the length is 0 the
file may not be empty. The operator panel does not use the date on the files, which
means that the time shown is not relevant. The operator panel can save the contents
in all files, which can be reached through FTP or accessed on an external memory
card with different types of delimiter characters (separators). The contents of the files
can be separated either with → [TAB] or the characters ; or :.
The properties for FTP delimiter characters are made under Setup/Terminal
Options in the configuration tool. The file name must not contain national charac-
ters. The operator panel’s FTP server can handle a maximum of three connected cli-
ents at the same time.
Note:
Files in the different directories use up the project memory. The command PSCE can
be used to include information about the available project memory in the file info.txt.
Using the command in projects with a large number of trend curves will considerably
slow down using FTP functions.
