Patent ID: 8819656

Claim:
A method for start-up and/or reconfiguration of a programmable, measuring field-device, whose installed hardware includes at least one measuring transducer reacting during operation to a chemical and/or physical, measured variable of a pourable and/or flowable medium and a microcomputer communicating with said measuring transducer during operation, said method comprising: installing the field device by means of the measuring transducer at a process vessel for conveying and/or holding pourable and/or flowable media for providing a process measuring point; booting the microcomputer and activating basic software held in a first memory provided within the field device and at least partially providing basic functionalities of the field device, in such a manner, that the basic software is executable by means of the microcomputer, so that the basic functionalities of the field device are available on the basis of interaction of basic software and hardware installed in the field device; executing the basic software in the microcomputer for determining at least one initial identification parameter set, said initial identification parameter set at least approximately identifying the process measuring point including an instantaneous installation situation of the field device and/or a medium located in the process vessel; and said initial identification parameter set being held at least temporarily in the field device; transferring said initial identification parameter set to a superordinated, electronic data processing system external to the field device; selecting from an ensemble of software products, taking into consideration said initial identification parameter set at least one upgrade software providing custom functionalities for the field device going beyond the basic functionalities, said upgrade software being held in a second memory located externally of the field device; transferring selected upgrade software, matched to the process measuring point, into a third memory provided within the field device; and activating upgrade software in such a manner that at least the transferred upgrade software is executable by means of the microcomputer, so that, with interaction of the upgrade software and hardware installed in the field device, custom functionalities of the field device are available.
