Limits when using the Java applet
When the Web-IO is accessed using the Java applet, there are
differences in how this is done depending on the browser.
All Mozilla-based browsers as well as Opera do not allow write
accesses to the Web-IO using the applet if the corresponding
Web page for example is loaded by the local hard drive of the
PC or by a Web server. If no password is assigned on the Web-
IO, read access can at least be used.
Microsoft Internet Exlorer on the other hand can be used
without limitations.
To be able to work with the Web-IO without restrictions, we
recommend saving the Web page as home.htm or user.htm in
the Web-IO. In this case the newest releases of most browsers
will allow unrestricted access.
The number of users who can use a Web page working the the
Java applet is limited to 3 at a time (if other access types than
HTTP are used, for example BINARY or UDP-ASCII, the number
of possible users is reduced).

A comprehensive example for using the Java applet can
be found on the Web page app.htm in the Web-IO.
