Assigning Measuring Points
If you add functions to the Voltage 3-phase function group, these are connected to the measuring point auto-
matically.
You connect the Voltage 3-phase function group to the voltage measuring points via the interface to the
measuring points. This assignment can only be made in DIGSI 5 via Project tree → Function group connec-
tions.
To connect the interfaces, set a cross at the intersection between the desired row and column in the matrix
(refer to
Operational Measured Values
The operational measured values are always present in the Voltage 3-phase function group and cannot be
deleted.
The following table shows the operational measured values of the Voltage 3-phase function group:
