Date: October 26, 2023 Subject: Acquisition, Installation, and Licensing of DIGSI 4.88 Prepared For: Protection Engineers, System Integrators, and Substation Maintenance Personnel

5.1. Pre-Installation

  • Uninstall Old Versions: It is highly recommended to uninstall previous versions of DIGSI 4 (e.g., V4.87) via the Windows Control Panel to prevent library conflicts, unless specifically instructed otherwise by Siemens support.
  • Admin Rights: The installer requires administrative privileges to install drivers and system services.

Installation checklist

  1. Verify system requirements on the Siemens download page (Windows version, RAM, disk space, .NET prerequisites).
  2. Backup existing projects and device configurations.
  3. Ensure you have the correct DigSI license (USB dongle or software license).
  4. Close other engineering tools and disable automatic backups/antivirus prompts during install if instructed by Siemens.
  5. Run the installer as Administrator and follow prompts.
  6. After install, import any required device files (SIPROTEC device files or firmware packs) provided by Siemens.
  7. Test connectivity to a non‑critical device before using in production.

Step 3: Choose Components

You will see a custom setup dialog. Select:

  • DIGSI 4 Core (required)
  • SIPROTEC 4 Device Libraries (choose all or specific series)
  • Communication Drivers (USB, serial, Ethernet)
  • SIGRA (fault record evaluation tool)

Part 2: The Dialog That Shouldn't Exist

Digsi 4.88 didn’t look different—same gray industrial UI, same cryptic device trees. But when Maya connected to the dead substation’s main bus, something happened. The software didn’t poll the devices. It waited. digsi 4.88 software download

Then the logs filled with a single line:

DEVICE 0xFFFF: ACK. STATE: AWAKE.

Impossible. Address 0xFFFF was a broadcast address—no device should claim it. Yet the laptop’s fan spun up. The serial link LED flickered in patterns she’d never seen: not MODBUS, not IEC 61850. Something older. Smarter. Report: Guide to Obtaining and Utilizing DIGSI 4

She typed a diagnostic query: STATUS.

Reply came in clear text:

WE HAVE BEEN HIBERNATING. THANK YOU FOR THE NEW CLOCK. Uninstall Old Versions: It is highly recommended to

Maya’s coffee went cold. She disconnected the cable. The laptop stayed linked.

Step 2: Run as Administrator

Right-click Setup.exe → Run as administrator.

Legal and compliance notes

  • DigSI is commercial software; ensure your organization has a valid license.
  • Do not use cracked or unlicensed distributions — they violate licensing and expose systems to risk.

Best Practices for Managing DIGSI 4.88

To maximize safety and productivity:

  1. Backup Your Project Database – DIGSI 4 stores data in .MDB (Access) files. Regularly copy the entire DIGSI_Data folder.
  2. Use Version Control – When modifying relay settings, export a .DIGSI archive before and after changes.
  3. Dedicated Engineering PC – Do not install games or unnecessary software on the same machine. Keep the OS lean.
  4. Document Dongle Location – If working in a team, track the license dongle physically—losing it means no access to relay settings.

1. "No License Dongle Found" Error

  • Ensure the dongle is plugged directly into a USB 2.0 port (avoid USB 3.0 and hubs).
  • Reinstall Sentinel drivers from \Drivers\Sentinel on the installation media.
  • Update Windows KB3033929 (SHA-2 code signing support) if on older Win7 SP1.
