Were you unable to start the SIMATIC Selection Tool properly? The following errors might have occurred.

Unable to establish connection with server

If you receive this message after starting the SIMATIC Selection Tool, kindly check as to whether your computer is properly connected to the internet.

Authentication at Proxy Server

Possibly, you need to log in at your proxy server with user name and password. For this, kindly specify your log-in details for your proxy server. In most cases, these are identical with your log-in details in the company network.

Which Java Runtime Environment do I need for using the SIMATIC Selection Tool?

Your minimum requirement is the Java Runtime Environment (JRE) of Version 1.4.2_02. The SIMATIC Selection Tool functions with the subsequent versions including 1.4.2_10 as well as with all versions of the 1.5.0-series.

In case there is no Java Runtime Environment installed on your computer, you can download the same here. You will need Administrator Rights for the installation. For this, you may contact your System Administrator, as the case may be.

  • For testing as to whether the required Java Version is installed on your computer, start the SIMATIC Selection Tool in the Industry Mall. Then, a script, which performs the test, is run.

  • If you know that a Java Version is installed on your computer and wish to find out the version number, please follow here. There the exact version of your Java installation will be given.
    (Hint: In case there is no Java Runtime Enviroment installed on your computer, a Download dialogue appears with a prompt for downloading the file "konfigurator.jnlp". If this is the case, close the Download dialogue and read the section A Download dialogue appears with a prompt for downloading the file konfigurator.jnlp.)


A Download dialogue appears with a prompt for downloading the file "konfigurator.jnlp".

If there is a prompt for downloading the file "konfigurator.jnlp" while starting the configurator (or the file "player.jnlp" while starting Java Web Start), this can have 2 causes:

  • If the needed Java version is installed on your computer, check the following setting in your browser: Select "Extras" - "Internet Options" - "Advanced" - "Safety" in the browser and deactivate the checkbox "Do not save encrypted pages on hard disk". Subsequently, start the SIMATIC Selection Tool in the Industry Mall.

  • There is no Java Runtime Environment installed on your computer. For testing as to whether a Java Runtime Environment is installed on your computer, start the SIMATIC Selection Tool in the Industry Mall. There, a script will be run for the testing.


No Java Runtime Environment could be recognised on my system. What should I do in order that the recognition works?

No Java Runtime Environment (JRE) could be recognised on your system. Possibly, you have deactivated the execution of ActiveX in your browser. If you activate the values "ActiveX Control Elements Safe for Scripting" and "Execute ActiveX Control Elements and Plug-ins" in your browser under "Extras" - "Internet Options" - "Safety" - "Adjust Level", the recognition of your Java Runtime Environment can be executed. If the settings have changed, start the SIMATIC Selection Tool in the A&D Mall. If still no Java Runtime Environment is recognised, there is possibly no Java Runtime Environment installed in your browser. Read the section Which Java Runtime Environment do I need for using the SIMATIC Selection Tool?.

    "Use Browser" is deactivated
    If your browser uses an "Automatic Configuration Script" for proxy recognition, Java Web Start cannot read out the proxy server needed in Version 1.4.2. In this case, the selection "Use Browser" is deactivated.
    For finding out the needed proxy server, click here, then mark "Manual" for proxies in Java Web Start and enter the detected settings under HTTP Proxy as well as HTTP Port. (In case the detection of the needed proxy server does not work, kindly contact your System Administrator and ask there about the proxy server needed for http://automation.siemens.com.)
