Abstract: The disclosed system and methods involve controlling the timing and order in which numerous motors and sensors exchange data over a data bus. The method can be used with, for example, motion control, automotive, industrial automation, and medical equipment applications using data buses. As an example of one possible medical equipment application, the method of exchanging data on a bus can be used with a remote catheter guidance system. The disclosed system and methods help optimize data exchange over a bus and avoid collisions by grouping the transmission of sensor readings, by grouping the transmission of motor commands, and by predetermining the order of these groups. Further, the method provides a way of ensuring that incomplete data sets are not exchanged over the bus. The method also provides a way of synchronizing motor actuation based on data transmitted to the data bus.
