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.

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.
