Engineering software for SIPROTEC 4 and SIPROTEC Compact

Engineering software for SIPROTEC 4 and SIPROTEC Compact - DIGSI 4


The PC operating program DIGSI 4 is the user interface to the SIPROTEC devices. It is designed with a modern, intuitive user interface. With DIGSI 4, SIPROTEC devices are configured and evaluated – it is the tailored program for industrial and energy distribution systems. For the system engineering of DIGSI 4 parameterized devices the IEC 61850 system configurator is used. The IEC 61850 system configurator is the manufacturer-neutral solution for the interoperable engineering of IEC 61850 products and systems. The tool supports the SCL (substation configuration description language) configuration files from the IEC 61850-6 through import or export of all formats (ICD/IID/CID/SCD/SSD/SED). Thus, IEC 61850 devices can be added and a complete IEC 61850 station is available for the substation automation Technology.

Features & functions

Engineering software for SIPROTEC 4 and SIPROTEC Compact DIGSI 4

Simple protection setting


From the numerous protection functions it is possible to easily select only those which are really required. This increases the clearness of the other menus.


Device setting with primary or secondary values


The settings can be entered and displayed as primary or secondary values. Switching over between primary and secondary values is done with one mouse click in the tool bar.


Assignment matrix


The DIGSI 4 matrix shows the user the complete configuration of the device at a glance. For example, the assignment of the LEDs, the binary inputs and the output relays are displayed in one image. With one click, the assignment can be changed.


CFC: Projecting the logic instead of programming


With the CFC (continuous function chart), it is possible to link and derive information without software knowledge by simply drawing technical processes, interlocks and operating sequences. Logical elements such as AND, OR, timers, etc., as well as limit value requests of measured values are available.




Special attention has been paid to commissioning. All binary inputs and outputs can be set and read out in targeted way. Thus, a very simple wiring test is possible. Messages can be sent to the serial interface deliberately for test purposes.
