Field device

A field device, comprising:

• a central data processing unit designed to receive device-related data, the central data processing unit having a buffer memory unit that can be rewritten for at least 106 write cycles, in which the device-related data can be at least buffer-stored up to a defined data volume;
• and
• a long-term memory unit that can be rewritten for a maximum of 5*105 write cycles,
• wherein the central data processing unit is configured to copy at least a portion of the device-related data as a common data packet from the buffer memory unit when the device-related data have reached the defined data volume in the buffer memory unit or when a defined time interval has been reached.

A method for storing device-related data in a field device, comprising:

• providing the field device, including:
• a central data processing unit designed to receive device-related data, the central data processing unit having a buffer memory unit that can be rewritten for at least 106 write cycles, in which the device-related data can be at least buffer-stored up to a defined data volume;
• and
• a long-term memory unit that can be rewritten for a maximum of 5*105 write cycles,
• wherein the central data processing unit is configured to copy at least a portion of the device-related data as a common data packet from the buffer memory unit when the device-related data have reached the defined data volume in the buffer memory unit or when a defined time interval has been reached;
• receiving device-related data;
• buffer-storing the received data in the buffer memory unit;
• and
• copying at least a portion of the device-related data as a common data packet from the buffer memory unit to the long-term memory unit as soon as the device-related data has reached the defined data volume in the buffer memory unit or as soon as a defined time interval has been reached.
