This Tag informs the last position of the event queue read by this Driver. This value must be stored by an application so that, when starting, this Driver can check how many events must be read, to avoid duplicating or losing events. Each module, with up to 64 inputs, contain its own queue. Therefore, if a device uses 4 (four) modules, use 4 (four) Tags of this type for that device.
