Sensors on conveyor in Robot Simulation app?

Hi all, is there a way to create a sensor able to detect a part moving on a conveyor and set/reset its IO signal using the Robot Simulation app? I know a similar feature is available in Factory Flow Simulation app (Programming | Add or Edit Sensor command) that creates a sensor object with 2 output signals and some specific properties (i.e. beam length and detection mode), but I can't find it in Robot Simulation app. In this case I'm able to create a sensor node and to manually add the IO signals to it, but how can I detect a moving part and trigger the signal when the part detection occurs? Thanks and BR, Alessandro
