is a version of Siemens' user-friendly PC program designed for commissioning and operating all digital SIPROTEC protection, combination, and bay devices. It serves as the primary interface between the engineer and the relay, allowing for: Parameterization: Setting up protection functions. Commissioning: Wiring tests and device diagnostics. Fault Analysis: Extracting and visualizing fault records. Control: Real-time monitoring and operation.
: Configure I/O and communication settings at a glance using a visual matrix.
While DIGSI 4.91 supports Windows 10, some older serial modem drivers (like those for 7XV585) may not be compatible, requiring a switch to Ethernet-based serial hubs for remote access.

Siemens DIGSI 4.91 is a legacy yet still widely used version of the engineering software for SIPROTEC 4 relays. Unlike newer DIGSI 5 (designed for SIPROTEC 5), DIGSI 4.91 remains critical for maintaining existing brownfield substations. This report clarifies that no legitimate “public download” link exists. Access requires a registered Siemens account, a valid software license, and often a maintenance agreement. The report outlines official acquisition routes, technical specifications, and security risks of unofficial downloads.
