Conventions
In this documentation, the names of elements in the software interface are specified in the 
language of this documentation. If you have installed a multi-language package for the 
operating system, some of the designations will be displayed in the base language of the 
operating system after a language switch and will, therefore, differ from the designations used 
in the documentation.
If you use the operating system Windows 10, you will find the Siemens SIMATIC programs in 
the Start menu under the menu command All apps > Siemens Automation.
