Use of application examples

Application examples illustrate the solution of automation tasks through an interaction of several components in the form of text, graphics and/or software modules. The application examples are binding and make no claim to completeness or functionality regarding configuration and equipment. The application examples merely offer help with typical tasks; they do not constitute customer-specific solutions. You yourself are responsible for the proper and safe operation of the products in accordance with applicable regulations and must also check the function of the respective application example and customize it for your system. Siemens grants you the non-exclusive, non-sublicensable and non-transferable right to have the application examples used by technically trained personnel. Any change to the application examples is your responsibility. Sharing the application examples with third parties or copying the application examples or excerpts thereof is permitted only in combination with your own products. The application examples are not required to undergo the customary tests and quality inspections of a chargeable product; they may have functional and performance defects as well as errors. It is your responsibility to use them in such a manner that any malfunctions that may occur do not result in property damage or injury to persons.

The Siemens terms of use (https://support.industry.siemens.com) shall also apply.

Security information

Siemens provides products and solutions with industrial security functions that support the secure operation of plants, systems, machines and networks. In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement and continuously maintain a holistic, state-of-the-art industrial security concept. Customers are responsible for preventing unauthorized access to their plants, systems, machines and networks. Such systems, machines and components should only be connected to an enterprise network or the Internet if and to the extent such a connection is necessary and only when appropriate security measures (e.g. firewalls and/or network segmentation) are in place. For additional information on industrial security measures that may be implemented, please visit ns undergo continuous development to make them more secure. Siemens strongly recommends that product updates are applied as soon as they are available and that the latest product versions are used. Use of product versions that are no longer supported, and threats.

Objective of the application examples

The application examples in this document show you how to extend your own web pages on the S7-1200/1500 web server. This document describes the examples provided for downloading. It is recommended to run the examples on a computer and simultaneously analyze them with the aid of this document.

Main contents of the application examples

The application examples cover the following key points:

Reading and writing with different variable types

Displaying the time

Outputting arrays (S7-1500 only)

Using the ENUM data type

HTTP redirection following an error (S7-1500 only)

Change language on user-defined pages

Transferring data without reloading pages

Displaying a datalog generated by the controller as a graph

Creating display elements

Displaying diagnostic information

Changing pictures using JavaScript

Restarting the CPU using a button

Logging in on the user-defined page

High-performance data transfer

Advantages

Integrated web server in the S7-1200 and S7-1500

The standard web pages for easy display of service and diagnostic information are enabled with a single click. In addition, you can create custom, user-defined web pages that are referred to

Access from anywhere

A web browser allows you to access the S7 web pages from anywhere in the world.

Application example

Universal use of the application example for the SIMATIC S7-1200 and S7-1500.

Benefits

No additional hardware and software required. The web server can be accessed over large distances using mobile communications devices such as tablet computers, smartphones, etc. Note The application examples in conjunction with the web server should not and cannot replace an HMI system.

Overall structure

The individual application examples consist of an S7 program running on an S7-

1200/1500 and a web page running on the integrated web server of the S7.

Exceptions are the examples in Chapter 13 and 15 that show general web functions without an S7 program. The web pages are opened using a web browser and consist of an HTML file as a basis. extension. Figure 2-1: Hardware configuration for the application examples
