Application

Global base values function (GBASVAL) is used to provide global values, common for
all applicable functions within the IED. One set of global values consists of values for
current, voltage and apparent power and it is possible to have twelve different sets.
This is an advantage since all applicable functions in the IED use a single source of
base values. This facilitates consistency throughout the IED and also facilitates a single
point for updating values when necessary.
Each applicable function in the IED has a parameter, GlobalBaseSel, defining one out
of the twelve sets of GBASVAL functions.

Setting guidelines

VBase: Phase-to-phase voltage value to be used as a base value for applicable functions
throughout the IED.
IBase: Phase current value to be used as a base value for applicable functions
throughout the IED.
SBase: Standard apparent power value to be used as a base value for applicable
functions throughout the IED, typically SBase=√3·VBase·IBase.

Signal matrix for binary inputs SMBI

Application
The Signal matrix for binary inputs function SMBI is used within the Application
Configuration tool in direct relation with the Signal Matrix tool. SMBI represents the
way binary inputs are brought in for one IED configuration.
Setting guidelines
There are no setting parameters for the Signal matrix for binary inputs SMBI available
to the user in Parameter Setting tool. However, the user shall give a name to SMBI
instance and the SMBI inputs, directly in the Application Configuration tool. These
names will define SMBI function in the Signal Matrix tool. The user defined name for
the input or output signal will also appear on the respective output or input signal.
