What's new in the Web Server function manual, Version 11/2019 compared to Version 12/2017
What's new?
What are the customer benefits?
Where can I find information?
New contents The CPU has an API (Appli-
cation Programming Inter-
face) as an interface for:
•Reading and writing
CPU data
•Executing functions (e.g.
backing up and restoring
the CPU configuration,
changing the operating
state)
The Web API supports all
common browsers and
command line programs,
such as cURL and Wget.
•Established standard mechanisms for
creating Web pages:
Automation Web Programming com-
mands (AWP commands) are no long-
er required for output of CPU data
•No dependency between custom Web
pages and CPU program:
No synchronization between user pro-
gram and Web server required by the
SFC 99 instruction
•Lower communication load:
A smaller data packet is transferred
between server and client (JSON in-
stead of HTML of the custom Web
page generated by the CPU). This im-
proves the communication perfor-
mance. The CPU needs less runtime
to generate the information and make
it available.
•Secure data traffic:
the Web API only supports the trans-
mission protocol "HTTPS"
Section API (Application Pro-
gramming Interface) (Pa-
ge 158)
Changed
contents
Scope of the function man-
ual expanded to include the
CPUs of the SIMATIC Drive
Controller
Webserver functions which you are famil-
iar with from the CPUs of the SIMATIC
S7-1500 can now also be used on the
CPUs of the SIMATIC Drive Controller.

2.1 Properties of the Web server
Benefits of the Web server
The Web server enables monitoring and administering of the CPU by authorized users over
a network. Evaluations, diagnostics, and modifications are thus possible over long distances.
Monitoring and evaluation is possible without STEP 7, only a web browser is required. Note
that you must take appropriate measures to protect the CPU from compromise (such as
restricting network access, using firewalls).
Activating the Web server
The web server is deactivated in the delivery state of the CPU. This means that you must
load a project in which the Web server is activated to enable access using the Web browser.
Security functions
The Web server provides the following security functions:
●Access via the secure transmission protocol "HTTPS" using the CA-signed web server
certificate
●User authorizations you can configure by means of user list
●Activation for specific interfaces

General information
2.1 Properties of the Web server

Function Manual, 11/2019, A5E03484625-AG 15
Web browser
You need a web browser to access the HTML pages of the CPU.
The web browsers listed below have been tested for communication with the CPU. Other
web browsers may also work, especially newer versions. However, if problems occur with
web browsers not mentioned here that cannot be rectified, use one of the following tested
web browsers:
●Microsoft Internet Explorer (Version 11.x)
●Microsoft Edge (Version 44.x)
●Google Chrome (Version 75.x)
●Mozilla Firefox (Version 64.x)
●Opera (Version 58.x)
●Mobile Safari and Chrome for iOS (iOS 12)
●Android browser (Android 7.x)
●Chrome for Android (Android 7.x to 8 (certificates work only to limited extent in Android
8))
Note
If you are using Internet Expl
orer, disable "Compatibility view" in the settings ("Options"
menu).
Note
For access to display devices with low screen resolution
, we recommend the use of basic
websites, see section
Basic websites (Page 156).
Note
Older
versions of the web browsers named above, which pr
eviously supported access to the
HTML pages of the CPU, continue to allow this. However, these older versions do not
support the new functions and HTML pages described in this edition.
Note
Two reserved communication connections are available to the We
b server for
communication with the CPU.
Depending on the web browser used, different numbers of connections to the CPU are
established. If more connections are available, more communication con
nections will be
established.
If no more connections are avail
able, display or functional problems may occur, because the
Web server will reject all other communication connections apart from the two that are
reserved.
For this reason, the web pages may no
t load fully.

Note
If you access the web server of the CPU
using a communications processor (CP), ensure
that the cache (temporary Internet files) is enabled in your browser. Choose the
"Automatically" option in the cache settings of your browser.
If
the cache is disabled or if a setting other than "Automaticall
y" is made in the cache settings
of your browser, this may result in slow access times and incomplete display.
Note
After a firmware update of the CPU, incorrect display of Web pages can occur in various
Web browsers. This is caused by problems of the
new CPU firmware with the cache of the
Web browser.
Solution:
Press F5 or clear the Web browser cache.
