### Double point Double point signals contain two bits of information that allow four different states, therefore they contain additional information compared to single point ones. INDETERMINATE state might, for example, mean that part of the equipment has been turned off or a mechanical part which does the switching has stuck between states. ERROR state might mean that both contacts are connected and there might be a short circuit in the equipment.
