    AltonaLab

    AltonaLab IoT software has a powerful and easy-to-use CAD environment, suitable for the design of complicated diagrams. Please read the documentation and enjoy the exciting world of IoT software! The new connection is established when the user left-clicks with the mouse over the block’s input or output, without releasing the mouse button drag the mouse to the direction of another input/output, and then release the mouse button over it. Double click over the block or click with the right mouse button opens the Parameters editor where every parameter is presented with the separated row. The parameter Name is very important and is unique within the diagram! When the diagram is locked, the application uses this parameter to determine the diagram's size. This is a tricky way to hide all the blocks and contours which are outside the visible area (the area determined from parameters LockedCanvasHeight / LockedCanvasWidth) and only controls from a visible area to be shown.
