A method for storing data for at least one of device state, device diagnosis and calibration of a field device in a cloud, wherein the field device has a self- monitoring functionality, wherein the method comprises:
- device-internal registering of first data for at least one of device state, device diagnosis and calibration by the field device and transferring the device-internally registered, first data from the field device to the cloud, and registering of second data for at least one of device state, device diagnosis and calibration of the field device by using at least of an external service computer and transferring the second data from the external service computer to the cloud, wherein both the first data and the second data are stored in the cloud;
- wherein the field device is embodied to register data for at least one of device state and device diagnosis device-internally according to a specified time plan and to transfer to the cloud;
- wherein the external service computer is embodied in the context of a calibration to register calibration data of the field device, wherein the second data transferred to the cloud from the external service computer comprise at least a part of the registered calibration data of the field device;
- the external service computer is embodied to register calibration data of the field device as part of a calibration device or in cooperation with a calibration device;
- wherein the calibration device is embodied for performing the calibration to set a measured variable measured by the field device to a specified value or sequentially to a plurality of specified values, wherein the associated measured value delivered from the field device is registered by using the external service computer;
- wherein the external service computer is a laptop, a tablet or a mobile device of a service technician;
- the first data of the field device and the second data of the field device are brought together in the cloud in a record associated with the field device;
- the data transferred to the cloud are stored in records, each of which is associated with a certain field device, wherein a record in the cloud for a field device is identifiable based on an identifier characteristic for the field device;
- wherein the characteristic identifier is one of the following:
- manufacturer and serial number of the field device, a universally unique identifier (UUID) of the field device, a medium access control (MAC) address of a network card of the field device, a unique identifier of a subscriber identity module (SIM) card of the field device.
