Abstract:
For simplifying and/or improving the updating of firmware of a control device, in particular of a safety controller, the invention provides a method and a system for updating firmware, in which a device-specific authorization check for performing a firmware update is performed by the manufacturer, and in case of a successful authorization check a device-specific activation code for performing the firmware update is provided, and for this purpose an enabling device is provided on the manufacturer's side and an updating device connectable to a control device on the user's side. The improvement is that the safe and secure firmware update proceeds under the control and long-term archiving of the manufacturer. The invention furthermore relates to a digital storage medium having instructions stored thereon for use when performing the method according to the invention.

Claim (Index 14):
A digital storage medium with instructions stored thereon, which when executed on a computer are adapted to perform the following method steps:\n a) retrieving first device data stored in a control device connected to the computer; b) generating a signed device file depending on the first device data and depending on information identifying a newly provided firmware; c) transmitting the signed device file to a central enabling device; d) receiving an activation code from the central enabling device in response to the transmitted signed device file, the activation code comprising second device data and a unique identification information item; e) performing a consistency check on the first device data retrieved in step a) and on the second device data contained in the received activation code, or again retrieving the first device data stored in the control device and performing a consistency check on the again retrieved first device data and the second device data contained in the received activation code; and f) only if the consistency check is successful, effecting update of the firmware of the control device using the new firmware.
