Understanding the Properties section
The Properties section displays the properties of the signal selected in the Signal pool. This section
is read-only for analog signals and power systems. For mapped binary signals, you can define the
Comparator to evaluate the GOOSE value.
Evaluating whether a binary signal is true or false
Every GOOSE has at least one attribute subject to a logical comparison. You can configure the
GOOSE's attributes comparator in Properties > Comparator. The binary signal is considered true if
the result of the comparison of all selected attributes is true.
Tip: Map the same GOOSE data attribute multiple times to create several binary inputs with different
conditions of the same payload.
To evaluate whether a binary signal is true or false:
1. In the Comparator section, clear the Inverted check box.
2. Select the attributes for comparison.
3. Configure the comparator of the selected attributes.
The logical conjunction (AND) of the result of each individual comparison defines whether the
binary signal is true of false.
To invert the result of each comparator, select the Inverted check box. This procedure is useful when
dealing with negative logic.
As shown in the following figure, the binary signal "Gin1" is true if the Boolean attribute value is true.
