A method for transferring data between movable and stationary units of a linear transport system having a controller and linear motor with stator and rotor for driving the movable unit along a guide rail. The stator includes the stationary units, each with one or more drive coils. The rotor is arranged on the movable unit, with one or more magnets. The stationary units each have at least one stationary antenna, and the movable unit has a movable antenna. The controller selects a stationary antenna based on position data of the moveable antenna and outputs a data packet to the stationary unit, with control and data signals transmitted via the selected stationary antenna. The control signal includes identification information to identify the stationary antenna. The data signal includes a communication frame with a start bit and user data following a start sequence arranged to trigger data receipt of the movable unit.
