Web Server - Siemens SIMATIC S7-1500 Function Manual

Preface
What's new in the Web Server function manual, Version 11/2019 compared to Version 12/2017
What's new?
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.
Changed Scope of the function man-
contents ual expanded to include the
CPUs of the SIMATIC Drive
Controller

What are the customer benefits?
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"
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.
