Siemens DIGSI 4.91 Software Report DIGSI 4 V4.91 is a Siemens engineering tool used for the configuration, parameterization, and operation of SIPROTEC 4 protection devices. While newer versions like Related search suggestions sent

are currently recommended for active support and advanced compatibility,

remains a relevant legacy release for maintaining specific SIPROTEC hardware. Download and Official Access Siemens primarily distributes DIGSI 4 through the Siemens Industry Online Support (SIOS) portal Trial Version

: The full software installation file typically functions as a 30-day trial

without functional restrictions if the word "Trial" is entered as the serial number during setup. Version Availability

: While legacy versions like V4.91 may be archived, Siemens often provides the latest stable releases (e.g., DIGSI 4 V5.00

) as the primary download, as these include cumulative device drivers and bug fixes. Download Content

: The digital version usually contains the main program, but users may need to download additional Device Drivers separately to support specific protection relay models. System Requirements for V4.91

Official product documentation specifies that V4.91 was designed for older environments but maintains limited compatibility with modern systems:

DIGSI 4.91 was released before Windows 11 existed. However, with the right tweaks, it runs flawlessly on modern systems.

There is no public direct download link from Siemens for legacy versions. Siemens pushes customers to their new platform, DIGSI 5 (for SIPROTEC 5 relays). However, you can still get DIGSI 4.91 through these official channels:

If you cannot legally obtain version 4.91, consider these options:

  • Driver Installation: When prompted, allow installation of "WibuKey" and "Siemens USB/COM drivers." This is critical for connecting to relays via the front port.
  • Activation: Insert your USB license dongle (green Wibu stick). DIGSI 4.91 will auto-detect it. If you have a floating network license, configure the license server IP during setup.
  • Reboot: restart your PC to finalize the driver registry.
  • DIGSI 4 is the engineering software used to parameterize, commission, and operate Siemens SIPROTEC protection devices. While DIGSI 5 and 6 exist for newer hardware (like SIPROTEC 5 and 7), the vast installed base of SIPROTEC 4 relays worldwide means DIGSI 4.91 remains a critical tool in the industry.

    Version 4.91 (often bundled as DIGSI 4.91 + CFC) is significant because it resolved many of the driver signature issues found in older versions (like 4.80) that plagued Windows 10 users.

    Stay safe, and respect the engineering intellectual property that keeps the power grid running.
