Remote-controlled programming of a program-controlled device

A method for remote programming of a device configured to be program-controlled, comprising:

• (a) remotely transmitting program data from a control station via a long-distance connection to an interface connected to the device;
• (b) buffering the program data at the interface;
• (c) remotely transmitting a legitimization from the control station to the interface;
• (d) forwarding the legitimization, unbuffered, to the device;
• (e) checking, by the device, the legitimization for validity;
• and
• (f) if the legitimization is determined to be valid, entering the program data in a memory of the device.

• (b) buffering the program data at the interface;
• (c) remotely transmitting a legitimization from the control station to the interface;
• (d) forwarding the legitimization to the device;
• (e) checking, by the device, the legitimization for validity, wherein the checking includes checking of a validity period of the legitimization;
• and
• (f) if the legitimization is determined to be valid, entering the program data in a memory of the device.

A system for remote programming of a device, comprising:

• an interface configured to receive program data and a legitimization;
• and
• a device configured to be remotely programmed and program-controlled, wherein the device includes a processor and a program memory, and wherein the device is operatively connected to the interface;
• wherein the interface is configured to:
• a) buffer the received program data;
• b) forward the received legitimization to the device;
• and c) transmit the buffered program data to the device after a positive determination of validity of the legitimization by the device.
