To delete data blocks that you have previously generated, click the "Delete data blocks"
button. STEP 7 deletes the control data block and all of the fragment data blocks from your
project that correspond to user-defined Web pages.
Configuring the entry page
In the Device Configuration of the CPU, you have the opportunity to designate a user-
defined Web page to be the entry page when you access the Web server from either a PC or
a mobile device. Otherwise, the entry page is the Introduction (Page 1017) standard Web
page.
To select a user-defined Web page to be the entry page, follow these steps:
1. Select the CPU in the Device Configuration view.
2. In the inspector window, select "Web server" from the CPU properties and enable the
Web server (Page 1003).
3. Select "Entry page" in the Web server properties.
4. Select "UP1" from the drop-down list to configure the Web server to display a user-
defined page upon access. (The other selection, "Intro page", sets the Web server to
display the standard Introduction Web page upon access.)
You must also configure the Everybody user to have the "open user-defined Web pages"
privilege (Page 1005) and include a call to the WWW instruction (Page 1059) in your
program.
After you have completed configuration and downloaded the project to the CPU, the Web
server can use the "Default HTML page" that you selected when you configured your user-
defined Web pages (Page 1057) as the entry page.
Note
The CPU must be in RUN mode to display a user
-defined entry page.
