Accessing the Web pages from a PC
You can access the S7-1200 standard Web pages from a PC or from a mobile device
through the IP address of the S7-1200 CPU or the IP address of any Web server-enabled
CP (Page 1010) in the local rack.
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 "https://ww.xx.yy.zz", where "ww.xx.yy.zz"
corresponds to the IP address of the S7-1200 CPU or the IP address of a CP in the local
rack.
The Web browser opens the Introduction standard Web page (Page 1017) or the Default
HTML page of your user-defined Web pages if you configured it to be the entry page
(Page 1058).
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 1082
) 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 "https://ww.xx.yy.zz/<page>.html", where <page> corresponds to
one of the standard Web pages:
● start (Page 1018) - general information about the CPU
● identification (Page 1019) - detailed information about the CPU including serial, order,
and version numbers, now called the Diagnostics page
● module (Page 1023) - information about the modules in the local rack and the ability to
update firmware
● communication (Page 1027) - information about the network addresses, physical
properties of the communication interfaces, and communication statistics
● diagnostic (Page 1022) - the diagnostic buffer
● variable (Page 1031) - CPU variables (tags) and I/O, accessible by address, PLC tag
name, or data block tag name
● watch (Page 1033) - watch tables
● filebrowser (Page 1037) - browser for accessing data log files or recipe files stored
internally in the CPU or on a memory card
● index (Page 1017) - introduction page to enter the standard Web pages
● login (Page 1013) - page to log in if no user is currently logged in; otherwise, the page is
blank.
