Updating user pages
User pages are not updated automatically. You can program the HTML code so that the
pages are updated automatically.
Pages which read out data from the controller, are always up-to-date due to regular updates.
Note
If the HTML page contains form fields for data input, automatic update can impair the correct
data input by the user.
To update the entire page automatically, you can add the following instruction in the <head>
area of your HTML page, whereby the number "10" stands for the update interval in
seconds:
<meta http-equiv="refresh" content="10">
Reference
The description of a user page is available in the chapter Example of a user page (Page 58).
Additional help for visualization with user-defined websites is available in the application
examples on the Internet:
● S7-1200 and STEP 7 V11
● S7-300 / S7-400 and STEP 7 as of V5.5
