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 12):
A system for updating firmware of a control device, comprising:\n a control device for process control comprising at least one control module, wherein the control module has associated therewith a firmware stored in a system memory of the control device; an updating device connectable to the control device; and a central enabling device; wherein the updating device is adapted:\n a) to retrieve, from the control device, first device data stored in the control device; \n b) to generate a signed device file depending on the first device data and depending on an information item identifying a new firmware; \n c) to transmit the signed device file to the central enabling device; \n d) to receive an activation code from the central enabling device in response to the transmitted signed device file; \n e) to perform a consistency check on the first device data retrieved in step a) and on second device data contained in the received activation code, or to again retrieve the first device data stored in the control device from the control device and to perform a consistency check on the again retrieved first device data and on second device data contained in the received activation code; and \n f) if the consistency check is successful, to effect update of the firmware of the control device using the new firmware; \n and wherein the enabling device is adapted:\n a) to check a signed device file received from the updating device; \n b) if the check is successful, to generate an activation code comprising second device data and a unique identification information item; and \n c) to transmit the activation code to the updating device in response to the received signed device file.
