Abstract
The present disclosure relates to a method for operating a measuring transducer of process automation technology, comprising at least the following steps: starting the measuring transducer by starting its operating system, wherein the operating system provides at least one interface; starting at least one interpreter, wherein the interpreter accesses the interface; and executing an extension in the interpreter. The present disclosure further relates to a measuring transducer for implementing the method.
Claims18
A method for operating a measuring transducer of process automation technology, wherein the measuring transducer includes:
- a microcontroller and an associated memory;
- a non-volatile memory;
- an operating system, wherein the operating system provides at least one software interface;
- a first communication interface embodied to communicate with a sensor;
- and
- a fieldbus interface embodied to communicate with a process control system, the method comprising:
- starting the measuring transducer and starting the operating system;
- instantiating a first interpreter in the measuring transducer, wherein the first interpreter is configured to access the at least one software interface;
- providing a first sensor, including:
- a sensor element;
- a microcontroller and an associated memory;
- and
- a second communication interface;
- connecting the first sensor to the measuring transducer by connecting the second communication interface with the first communication interface;
- transferring a unique identification from the first sensor to the measuring transducer;
- executing a first extension in the first interpreter, wherein the first extension includes first-sensor-specific software, and wherein the first-sensor-specific software is determined based on the unique identification of the first sensor;
- performing a measurement with the first sensor to obtain a first measured value;
- transferring the first measured value from the first sensor to the measuring transducer;
- processing the first measured value in the measuring transducer using the first-sensor-specific software;
- and
- transferring the processed first measured value from the measuring transducer to the process control system.
A measuring transducer, comprising:
- a microcontroller and associated memory;
- a non-volatile memory;
- a first communication interface;
- a fieldbus interface embodied to communicate with a process control system;
- a sensor including a sensor element embodied to detect a physical measurand and to convert the physical measurand to an electrical signal, the sensor including a unique identification, wherein the sensor is connected with the measuring transducer via the first communication interface;
- an operating system having at least one software interface for the exchange of information;
- and
- at least one interpreter configured to access the at least one software interface,
- wherein the measuring transducer is configured to:
- transfer from the sensor the unique identification;
- and
- transfer from the sensor sensor-specific software based on the unique identification,
- wherein the at least one interpreter is embodied to execute an extension, wherein the extension includes the sensor-specific software.
