[ EN ]
CLAIMS:
1. A method for providing measured values for end customers, comprising the steps of: recording a process variable by a measured value pick-up device wherein the device, a converter, a computer unit and a communication unit are part of a sensor; digitizing the process variable into a measured value by the converter connected to the device via a first data line; transmitting the measured value from the converter to the computer unit; transmitting the measured value from the computer unit to the communication unit over a second data link; receiving by the sensor a request for the measured unit from a process control unit; converting the measured value by the communication unit into a message and transmitting the message from the sensor to the process control unit wherein the message comprises the measured value, data bus address of the sensor S and a data bus address of the process control system; and counting and storing the number of measured values transmitted from the sensor to the process control unit by the computer unit.
2. The method as defined in claim 1, wherein the transmitting steps between the sensor and the process control system are conducted over a data bus system DBS.
3. The method as defined in claim 1, wherein the transmitting steps between the sensor and the process control system are conducted by radio.
4. The method as defined in claim 1, further comprising the step of storing the number of measured values transmitted in the process control system.
5. The method as defined in claim 2, further comprising the step of storing the number of measured values transmitted in the process control system.
6. The method as defined in claim 1, further comprising the step of transmitting the number of measured values over the internet from the sensor to a database at a field transmitter manufacturer.
7. The method as defined in claim 2 further comprising the step of transmitting the number of measured values over the internet from the sensor to a database at a field transmitter manufacturer.
8. The method as defined in claim 3, further comprising the step of transmitting the number of measured values over the internet from the sensor to a database at a field transmitter manufacturer.
9. The method as defined in claim 1, further comprising the step of transmitting the number of measured values over radio from the sensor to a database at a field transmitter manufacturer.
10. The method as defined in claim 2, further comprising the step of transmitting the number of measured values over
radio from the sensor to a database at a field transmitter manufacturer.
11. The method as defined in claim 3, further comprising the step of transmitting the number of measured values over radio from the sensor to a database at a field transmitter manufacturer.
