S7-CP Advanced as Web server: HTML process control
10.3 Accessing the Advanced CP via a Web browser
Configuring and commissioning S7 CPs for Industrial Ethernet
166 Configuration Manual, 09/2013, C79000-G8976-C182-13
URL: Uniform Resource Locator
In the World Wide Web, addressing using URLs has become standard. You can also access
the Advanced CP with your Web browser using the URL. This URL can have almost any
complexity but consists in principle of four essential parts. The following schematic illustrates
the structure (typical URL) and shows the contents for calling Advanced CPs.
Server name [:port] ->
IP address -> "142.80.00.01"
[File directory] -> "/net"
File name -> "/page.html"
Name of the HTML page -> "index.htm"
When shipped, the Advanced CP does not have an HTML page "index.htm". As a substitute,
you then reach the Web diagnostics of the CP with this URL.
When you access the Advanced CP using a Web browser, use the HTTP or HTTPS protocol
to address the Web server on the Advanced CP:
You inform the CP of the IP address during configuration with STEP 7 (see Section Setting
further CP properties (Page 42)). If you have an attachment from Industrial Ethernet to your
intranet or to the Internet, the CP can be contacted using the IP address in the intranet or
Internet.
A detailed description of the structure of the IP address and the options of creating subnets
or subnet masks is beyond the scope of this manual. You will find information on this in the
online help of STEP 7 and in the references in the appendix.
