Diagnostics via the S7-1200 Web server
Diagnostics via the S7-1200 Web server
The Web server of the S7-1200 enables you to access data from Web pages regarding your
CPU and the connected components.
The Web server also enables user-defined Web pages to be integrated which display
contents of the CPU as well as the AS-i master CM 1243-2.
The diagnostic data of the AS-i master CM 1243-2 can also be read via the user program
interface (alarms, diagnostic data records) and integrated into the Web pages.
Any HTML authoring software can be used to create the Web pages – you can construct and
arrange the pages as you wish.
The connection between the Web page contents and the data of the user program is
established using "AWP commands" (Automation Web Pages) which you insert in your
HTML code.
A detailed description of these possibilities can be found in the system manual for S7-1200
in the section "Web server".
