Configuration in STEP 7 of the example Web page

To include the "Remote Wind Turbine Monitor" HTML page as a user-defined Web page for

the S7-1200, you configure the data about the HTML page in STEP 7 and create data blocks

from the HTML page.

Access the CPU Properties for the S7-1200 that controls the wind turbine, and enter the

configuration information in the User-defined pages properties of the Web Server:

Configuration fields

● HTML directory: This field specifies the fully-qualified pathname to the folder where the

default page (home page or start page) is located on the computer. The "..." button allows

you to browse to the folder that you need.

● Default HTML page: This field specifies the filename of the default page or home page of

the HTML application. The "..." button allows you to select the file that you need. For this

example, WindTurbine.html is the default HTML page. The Remote Wind Turbine Monitor

example only consists of a single page, but in other user-defined applications the default

page can call up additional pages from links on the default page. Within the HTML code,

the default page must reference other pages relative to the HTML source folder.

● Application name: This optional field contains the name that the Web browser includes in

the address field when displaying the page. For this example, it is "Remote Wind Turbine

Monitor", but you can use any name.

No other fields require configuration.

To use the Remote Wind Turbine Monitor as configured, generate the blocks, program the

WWW instruction (Page 1059) with the number of the generated control DB as an input

parameter, download the program blocks, and put the CPU in run mode.

When an operator subsequently accesses the standard Web pages for the S7-1200 that

controls the wind turbine, the "Remote Wind Turbine Monitor" Web page is accessible from

the "User-defined pages" link on the navigation bar. This page now provides the means to

monitor and control the wind turbine.
