Fairly new to PLC's/rslogix....Is it possible/practical to capture elapsed time using (2) photosensors? For example, I would like to capture the time elapsed between input 1 being on and input 2 coming on. I am thinking about calculating velocity in some physics experiments using a small dc motor powered model car that would "cruise" past input 1 and input 2. I could then take that time and calculate velocity. If I can do it, how accurate would it be if the sensors wer approximately 3 feet apart. Thanks!!
