VariableIdx
(read/write)
For PCElements only, gets/sets the index of a state variable turning it into the active state variable for the active circuit element. If the index exceeds the number of state variables or the active circuit element is not a PCelement this will trigger an error message.
Example
% Create DSS object
DSSObject = actxserver('OpenDSSEngine.DSS')
if ~DSSObject.Start(0),
disp('Unable to start openDSS');
return
end;
DSSText = DSSObject.Text;
DSSCircuit = DSSObject.ActiveCircuit;
DSSLines = DSSCircuit.Lines;
% Compile a model
DSSText.Command = 'Compile C:\myPath\myModel.dss';
DSSActiveElement = DSSCircuit.ActiveCktElement;
% Activates the generator located in this model
DSSCircuit.SetActiveElement('Generator.G1');
% gets the names of all the state variables of the active element
mySVNames = DSSActiveElement.AllVariableNames;
% requests for state variable Pshaft
Value = 1.23;
%Activates variable PShaft(4) by index
DSSActiveElement.VariableIdx = 4;
DSSActiveElement.VariableValue = Value;
mynewVal = DSSActiveElement.VariableValue;
myVarName = DSSActiveElement.VariableName;
