The answer to question 3 simply depends on the need to recall a data history. If a PC should be able to connect to the WebNet, check the data output during the last e.g. 24 hours and then disconnect, the WebNet should store a data history.
Figure 23 is an example, showing a principal schematic of a setup with a device (a sensor), a WebNet that does both protocol translation, data storage and applet serving, and a PC. The PC displays the web page from the WebNet in its browser, including the applet.
Please refer to [5] for a full introduction and reference to WebScript, as well as a number of explained examples to get you started making WebNet applications.
