Can PCS 7 V9.1 Switch the European OS Runtime to Russian?

PCS 7 V9.1 SP1 European runtime can switch among configured languages for which the version provides support, but Siemens' documented European system-dialog languages are English, German, French, Spanish, and Italian. Russian is not listed. Manually translating selected project-authored text is a different task and does not establish a complete Russian PCS 7 runtime interface.

Answer and Language Scope

For PCS 7 V9.1 SP1 European runtime, the documented language switch does not provide Russian for standard OS system dialogs: Siemens lists English, German, French, Spanish, and Italian for that version. An operator can switch among configured languages, but the manual requires the corresponding foreign-language texts to be configured. Manually translating selected project texts is a separate scope and does not establish a complete Russian PCS 7 interface.

What the Runtime Language Switch Changes

The PCS 7 OS process-control manual describes switching the runtime user interface and process-picture text elements. It also notes that the available choices depend on the installed PCS 7 version. In the European version, standard system dialogs such as message filtering and trend configuration are documented for English, German, French, Spanish, and Italian; Russian is not in that list. A language selection therefore cannot be treated as proof that every system message or dialog is translated.

Switch a Supported Language

This procedure is for a language that is configured for the OS and supported by the installed PCS 7 version:

In process mode, switch to button set 2.
Select the Change language icon. The Change language dialog opens.
Select the checkbox for the required configured language.
Confirm the displayed message that the language change has been made.
Inspect the user-interface functions and process-picture text elements. If a picture element does not refresh, select that picture again as Siemens instructs.

The documented result is a runtime language change for the configured texts; it does not create translations that have not been authored.

Custom Project Texts Versus Standard PCS 7 Texts

A project may have user-authored picture labels, messages, and other text that need translation independently of Siemens-provided system dialogs and faceplate content. The version-matched source reviewed here does not provide a supported step-by-step method for replacing the European V9.1 runtime's system-dialog language set with Russian, nor does it verify editing @language.pdl as a complete replacement for a localization package.

If only custom process text must be Russian, first establish from the installed PCS 7 V9.1 and WinCC documentation which project-language entries and text types are supported. Inventory the content to translate, include the required fallback language, and validate each message and picture in runtime. Do not assume this changes standard PCS 7 system dialogs.

Verification

In a non-production environment or approved OS test window, select one of the configured languages listed for the installed version and verify the operator interface, system dialogs, messages, and process-picture text separately. Re-select a picture if some text does not refresh. For a Russian requirement, verify against the version-matched Siemens documentation and the actual installed components which text classes can be displayed in Russian; a translated sample picture alone does not demonstrate complete localization.

Limitations and Operational Precautions

The directly reviewed source is OS process control (V9.1 SP1), which states there are no major changes between PCS 7 V9.1 and V9.1 SP1. Its language list is specific to standard system dialogs for the European PCS 7 version. This article does not verify current package price or availability, the specific contents of a Russian localization package, or a complete manual Russian translation workflow. Avoid editing internal PDL or runtime files as a substitute for documented language configuration.

Engineer FAQ

The source reply recommends the Russian Localization package and mentions manual work as an alternative. The verified V9.1 runtime documentation supports switching configured, version-supported languages, but its European system-dialog table does not include Russian. Therefore, a manual workaround must be scoped to project-authored text unless Siemens confirms broader support for the exact installed version and WinCC components.
