It includes 2 panels that show the gates combination that represent the logics as they
are configured in the memory of the PC and in the internal memory of the relay
respectively.
Only the part related to the PC is editable. All the logics mechanism is composed of
three gates, two input gates (AND and OR) and a configurable gate that joins the result
of the two input gates. The operation criteria of these gates are the same used in digital
electronics.
Each signal can be inverted by double clicking on the input line of the gate where the
signal is located; a circle that indicates the inversion will then appear. Double clicking
again on the same input, the signal becomes direct and the circle disappears. This
operation can also be performed using the corresponding button that lies on the upper
panel on the right, clicking first on the input and then again on the inversion button.
Adding an input to a gate can be accomplished in two ways:
In the signals list, double click on the desired signal and that signal will
automatically become the input signal of the OR gate. Double clicking the signal
while pressing the “Shift” button will make that signal become the input of the
AND gate.
Drag the desired signal with the mouse and drop it onto the desired gate.
Up to 16 signals can be connected to each of the gates. The gate inputs number
automatically increase or decrease as the inputs are added or removed respectively. To
remove an input from a gate, click on the input to remove; it will become red and hitting
the “Del” key or clicking on the “Remove signal” button from the upper panel will remove
the input. When clicking on a signal located in any of the gates, a detailed explanation of
the meaning of that flag or signal will appear. When clicking a signal, the signals
explorer will automatically select that signal.
The equation that represents the selected logic is shown in the upper right panel; it is
automatically updated as the signals in the inputs of the gate change. The type of the
third gate can be changed by clicking on the opposite gate-type name above it.
