Accessing the Web pages from a PC
You can access the S7-1200 standard Web pages from a PC or from a mobile device.
To access the S7-1200 standard Web pages from a PC, follow these steps:
1. Ensure that the S7-1200 and the PC are on a common Ethernet network or are
connected directly to each other with a standard Ethernet cable.
2. Open a Web browser and enter the URL "http://ww.xx.yy.zz", where "ww.xx.yy.zz"
corresponds to the IP address of the S7-1200 CPU.
The Web browser opens the Introduction page.
Note
Use a secure Virtual Private Network (VPN) to connect to the S7
-
1200 PLC Web server from
a location outside your protected network. Be aware also of any
constraints (Page 664) that
your Web environment or operating system might impose.
Alternatively, you can address your Web browser to a specific standard Web page. To do so,
enter the URL in the form "http://ww.xx.yy.zz/<page>.html", where <page> corresponds to
one of the standard Web pages:
● start (Page 614) - general information about the CPU
● identification (Page 615) - detailed information about the CPU including serial, order, and
version numbers
● module (Page 616) - information about the modules in the local rack and the ability to
update firmware
● communication (Page 620) - information about the network addresses, physical
properties of the communication interfaces, and communication statistics
● diagnostic (Page 616) - the diagnostic buffer
● variable (Page 620) - CPU variables and I/O, accessible by address or PLC tag name
● filebrowser (Page 622) - browser for accessing data log files or recipe files stored
internally in the CPU or on a memory card
● index (Page 613) - introduction page to enter the standard Web pages
● login (Page 610) - page to log in as a different user or log out. (Note that a login window
is available from every page of the PC standard Web pages, but that the login page is
necessary to log it from a mobile device.)
For example, if you enter "http://ww.xx.yy.zz/communication.html", the browser displays the
communication page.
