In the following cases, the task is not processed further after issuing the
function call:

The controller must first read the file, e. g. ServerTestFile.txt and save it to
the local file system as, e. g.,
LocalTestFile.txt
.
 An error has occurred.
This function is processed in the following steps:
Step Description
1
The controller sends a command to the FTP server that the content of the
file ServerTestFile.txt must be transmitted.
2 The controller receives the contents of the file ServerTestFile.txt .
3 The controller writes the contents to the file LocalTestFile.txt .
4 If ... ... then ...
... no errors have occurred, ... ... the file has been copied
successfully, the function is
terminated and value
0
is returned.
... errors have occurred, ... the function is terminated and a
negative value is returned.

The function parameter for the local file may contain the path to this file,
e.g.
"/Data/TestFiles/LocalTestFile.txt"
.

If the file system of the remote network node supports this, the function
parameter for the file located on the FTP server can also contain the path
to this file. Otherwise, the directory must be set beforehand using the
command FtpDirChange() .
 The file system of a JC-120MC supports both options.
 Writing to a file (see page 169)
