Web-Link allows files to be distributed to users via a web/ftp server.
An administrator uploads files to the server using Web-Link Administrator, and then each user downloads the files using Web-Link.
Some data loggers can upload data directly to a web server.
The list of files for downloading can be prepared either by the administrator or by the user.
Files can also be sent from the user to the administrator, to backup the files or so that the administrator can provide support to the user.
To use the system, the system administrator will send to the user...
Use, and the folders for the files will come from the Administrator (via the web server).
Users can overide the folders where the files will be saved on your PC.
The application folder is for files used by the application e.g.
The data folder, user folder and user current folder are where data files are saved (depending on file location).
The programme can be set to automatically download at intervals - every hour for example.
The programme can also run automatically every time the computer is started - when it is running it will appear as an icon in the bottom tool bar.
The files tab shows details of each file that will be processed, either downloaded or uploaded.
Files can be data from loggers; current crop ET values; sensor calibrations; weather from other systems....
The file list can come from either the administrator (in which case users do not need to do anything) or the user can add and edit the list of files.
By setting the 'from' date to the beginning of the season, only data after this date will be downloaded. (Only for 'incremental' download)
This option allows a third party (not the administrator) to look at all data files belonging to a user.
The third party would need to be given the user's password.
A special folder to hold all user data should be entered e.g.
All the files for a user on the server will be downloaded to a folder for the user below this folder e.g.
Web-Link is potentially dangerous - it uploads and downloads files to your PC.
Every PC that connects to the internet should be running a firewall (such as ZoneAlarm) , and the firewall should ask you to confirm it is ok when Web-Link tries to access the internet.
The name of the programme is
WebLink.EXE, and it will identify itself to the ftp and http server as
The firewall should again ask for confirmation after an upgrade to the software has been installed.
If the list of files itself is to be downloaded from the web server (and this is the default), the
files.txt will be copied from the server to your PC, and saved in the data folder.
You can then see the list of all files that will be uploaded or downloaded from your PC on the files tab.
This list should be carefully checked before using.
Files should normally only be in the Application or Data folders, but WebLink can also upload files from anywhere on your PC.
This is to allow uploading INI files in the
A potential problem is that if you use
Run at startup, the list of files will be processed automatically.
The file list could be changed at any time by the Administrator, but the user might not regularly check the list.
So you need to either trust the Administrator and their system, or remember to keep checking the files list.
Every time a file is uploaded or downloaded it is logged in
ftp.log, in the data folder.
A special 'file to process' called
DIR will generate a directory listing of all files in the Application and Data folders, and sent it to the Administrator.
This is to help with support, if you are having problems
Another special 'file to process' is
FROMDATE. This will change the season start date on the 'new season' tab, so that only data for the new season is downloaded.
The following command line switches are available. They can be entered on a shortcut command line.
|/S||Startup. Run minimised; wait 60 secs; login; process all files. Designed for running at startup.|
|/D||Download all files that are specified for downloading.|
|/U||Upload all files that are specified for uploading.|
|/M||Run WebLink minimised.|
|/X||Run, and then exit. e.g. |
