Parameters and Routing in DIGSI 5
Interface with Measuring Points
The function group receives the required measured values via its interfaces with the measuring points. If you
are using an application template, the function group is already connected to the necessary measuring points.
If you add functions to the function group, they will automatically receive the measured values from the
respective voltage or current measuring points. If you add functions to the function group but the measuring
point necessary for this is not connected, DIGSI 5 reports an inconsistency.
Configure the measuring points in DIGSI 5 via the Function group connections editor. You can find more
detailed information in chapter
The function group has the following interfaces with the measuring points:
•
3-phase voltage
The measurands from the 3-phase voltage system are supplied via this interface. There are various types
of transformer connections possible. All values that can be calculated from the measurands are also
provided via this interface. The function group must always be linked to the V-3ph measuring point.
If you want to test or change the connection between the voltages and the V-3ph measuring point,
double-click in the DIGSI 5 project tree → (Name of the device) on Measuring point routing (Connec-
tion type = 3 phase-to-ground voltage).
•
3-phase current (optional)
The measurands from the 3-phase power system are supplied via this interface. Depending on the
connection type of the transformers, these are, for example, I
calculated from the measurands are also provided via this interface. The function group must always be
connected to the I-3ph measuring point.
You can connect the 3-phase current interface to a maximum of four 3-phase current measuring points.
If 2 current measuring points have been connected with the 3-phase current interface, the total current
is also determined from measured values from both measuring points in the function group. All functions
in the function group have access to these values.
