Java Applets
Subject to errors and modifications:
pollingrate
Mit diesem Parameter wird durch value festgelegt, in welchem
Intevall (in ms) Inputs, Outputs oder Counter aktualisiert wer-
den sollen.
Here is an example:
<applet name="dio0" archive="dio.jar" code="dio.class"
codebase="http://172.16.232.11" width="0" height="0">
<param name="device" value="0">
<param name="showerrors" value="off">
<param name="inputpolling" value="on">
<param name="outputpolling" value="on">
<param name="counterpolling" value="on">
<param name="pollingrate" value="2000">
</applet>

Both the parameters and the values are case-sensitive.
Using the applet with JavaScript
To work with the applet, corresponding JavaScript functions
must be declared in the header of the Web page.
There are 4 functions for read-only access:
Password protection
<script language="JavaScript" type="text/javascript">
<!--
function setPassword()
{ document.applets["dio0"].setPassword('Administratorpasswort');}
If an Administrator or Operator password has been set for the
Web-IO, the
setpassword function must be invoked so that you
can work with the applet. Instead of a static password, the
password may of course also be queried by the user using an
input field and then passed on.
