A method for remote programming of a program-controlled device, and a system having an interface to receive program data and a legitimization, as well as a remotely programmable, program-controlled device, which includes a processor and a program memory, are provided. In the method, program data are remotely transmitted from a control station to the interface and buffer-stored there in a buffer store. Subsequently, a legitimization is transmitted from the control station to the interface, and from there to the program-controlled device. The device checks the legitimization and imports the program data from the buffer store if the legitimization check is positive.
