Method and Industrial Automation System with a System for Embedding a Web Application to be Embedded in a Surrounding Web Application

A method for embedding a web application to be embedded into a surrounding web application, the web application to be embedded being provided to run in a separate execution and display region of the surrounding web application, the method comprising:

• providing the web application to be embedded by at least two web servers;
• defining at least one criterion which is used to determine the web server of the at least two web servers of which the provided web application to be embedded is embedded into the surrounding web application;
• interconnecting the web application to be embedded and the at least two web servers communicatively via a communication facility, the criterion relating to the communication in the communication facility, and the criterion being a reduction of data traffic in the communication facility between the at least two web servers;
• wherein functions in an industrial automation system are provided by the web applications, wherein the automation system at least one of (i) controls and/or regulates and (ii) monitors a process;
• and
• wherein the criterion relates to a reduction of the data traffic which occurs due to transferring process values of the process between the at least two web servers.

An industrial automation system, in particular process control system, comprising:

• a system for embedding a web application to be embedded into a surrounding web application, the web application to be embedded being provided to run in a separate execution and display region of the surrounding web application;
• and
• at least two web servers which provide the web application to be embedded,
• wherein the system is configured to determine, on the basis of at least one criterion, the web server of the at least two web servers of which the provided web application to be embedded is to be embedded into the surrounding web application;
• wherein the web application to be embedded and the at least two web servers are communicatively interconnected via a communication facility and in which the criterion relates to a reduction of data traffic in the communication facility between the at least two web servers;
• wherein the web applications provide functions of the automation system;
• wherein the automation system at least one of (i) controls and/or regulates and (ii) monitors a process;
• and
• wherein the criterion relates to a reduction of the data traffic which occurs due to transferring process values of the process between the web servers.
