Web server
12.7 User-defined Web pages
S7-1200 Programmable controller
1060 System Manual, V4.2, 09/2016, A5E02486680-AK
STEP 7 creates the control data block when you click "Generate blocks" and displays the
control DB number in the User-defined Web pages properties. You can find the control DB
as well in the Program blocks folder in the project navigation tree.
Typically, your STEP 7 program uses the control DB directly as created by the "Generate
blocks" process with no additional manipulation. However, the STEP 7 user program can set
global commands in the control DB to deactivate the web server or to subsequently re-
enable it. Also, for user-defined pages that you create as manual fragment DBs (Page 1057),
the STEP 7 user program must control the behavior of these pages through a request table
in the control DB. For information on these advanced tasks, see the topic Advanced user-
defined Web page control (Page 1078).
Downloading the program blocks to the CPU
After you have generated the blocks for user-defined Web pages, they are part of your STEP
7 program just like any other program blocks. You follow the normal process to download the
program blocks to the CPU. Note that you can only download user-defined Web page
program blocks when the CPU is in STOP mode.
