Changing the language of the TwinCAT development environment

Installing Visual Studio® language packs

TwinCAT 3 uses Visual Studio® ("Professional" functionality or higher) or the Visual Studio® Shell as the development environment. Various language packs are offered for Visual Studio®. A distinction is thereby made between the functional specification of the development environment and the supported languages.

The languages supported by Visual Studio® are described on the MSDN page:

Calling Visual Studio® with language parameters

It is also possible to quickly check the installed menu language of Visual Studio® and to change the language with a direct call.

1. Enter the following command in the command line or in the Run window:
devenv /lcid 1031 for the German menu language
or
devenv /lcid 1033 for the English menu language
Visual Studio® or the TwinCAT 3 development environment (Visual Studio® Shell) then opens with the specified menu language, provided this language is installed.
