To work with DIGSI 4 V4.91, you need a PC with the following minimum hardware specifications, independent of the operating system:
The integrated Continuous Function Chart (CFC) editor allows users to create custom interlocking logic, control sequences, and automated switching operations without advanced programming knowledge.
A visual tool that offers an at-a-glance view of device configurations, such as LED assignments and output relays. Continuous Function Chart (CFC): Test, check, and start up protection devices onsite
To ensure stable operation, DIGSI 4.91 requires specific hardware and operating system environments. Because DIGSI 4 is a legacy software platform, compatibility with modern operating systems requires specific attention. Requirement Minimum Specification Recommended Specification Windows 7 (32-bit / 64-bit) Windows 10 (64-bit) Professional/Enterprise Processor Intel Core i3 or equivalent (2.0 GHz) Intel Core i5 / i7 or higher RAM 8 GB or more Hard Disk Space Approx. 5 GB free space SSD with 10+ GB free space Display 1024 x 768 resolution 1920 x 1080 (Full HD) Interfaces
Provides a comprehensive view of device configurations, allowing users to assign LEDs, binary inputs, and output relays with a single click.
Once the download is obtained, the installation process is straightforward but requires attention to detail regarding drivers. Run setup.exe to begin the installation wizard.
