DIGSI 4 V4.96 Full Version DIGSI 4 V4.95 Full Version Trial Information: You can use these versions for a 30-day trial period without a license key. To activate this, enter the term
as the serial number during the setup process. After 30 days, a permanent license key is required for continued use. Key Features of DIGSI 4
DIGSI 4 is designed to simplify the lifecycle of SIPROTEC devices, from initial hardware setup to advanced fault analysis.
The Siemens DIGSI 4.95 is the latest engineering software version used for the configuration, parameterization, and operation of SIPROTEC 4, SIPROTEC Compact, and SIPROTEC 3 protection devices.
While the software is often requested as a "full download," it is officially distributed as a professional engineering tool that requires a valid license for full functionality. Key Features of DIGSI 4.95
Device Integration: Supports the entire range of SIPROTEC 4 and Compact units via a unified interface.
CFC Editor: Allows for the creation of customized logic through Continuous Function Charts (CFC).
SIGRA Integration: Often bundled or used alongside SIGRA for detailed fault record analysis and visualization.
IEC 61850 Support: Advanced configuration for substation automation and communication protocols.
Operating System Compatibility: Version 4.95 is specifically updated to ensure stable performance on Windows 10 (64-bit) and Windows 11. Official Acquisition and Updates
Siemens typically provides updates and service packs through their official Siemens SIOS (Industry Online Support) portal.
Trial/Update Versions: Siemens often offers "Service Packs" (e.g., SP1) which can act as a full installer if you have an existing license.
License Key: A "Trial License" may allow for short-term use, but for industrial and permanent applications, a USB Dongle or a License Key Disk is required.
Device Drivers: After installing the base software, you must also download and install the specific Device Drivers (templates) for the relay models you are working with (e.g., 7SJ62, 7UT613). Important Considerations
Compatibility: If you are transitioning from older versions like 4.8x, ensure your project files are backed up; 4.95 can migrate older projects, but they may not be backward compatible once saved.
Hardware Interface: Ensure you have the correct USB-to-Serial or Ethernet drivers to connect to the physical SIPROTEC relays.
