Abstract
A field device for use in a process control system having embedded firmware stored in a a nonvolatile memory. The firmware includes computer-executable instructions for performing fixed behaviors and/or standard measurements as well as a runtime interpreter. The interpreter executes application specific code downloaded to the field device. When executed, the application specific code performs custom field device functions.
Claims21
A field device for use in a process control system comprising:
- a processor;
- and
- a nonvolatile memory storing embedded firmware, said firmware including computer-executable instructions that, when executed by the processor, perform:
- at least one of a fixed behavior and a measurement to implement a predetermined function of the field device;
- and
- a runtime interpreter, said interpreter executing application specific code to perform a custom function of the field device, wherein the application specific code is downloaded to the memory separate from the embedded firmware.

A computer-implemented method of operating a field device for use in a process control system comprising:
- performing at least one of a fixed behavior and a measurement in embedded firmware to implement a predetermined function of the field device;
- and
- performing a runtime interpreter in embedded firmware, wherein the interpreter executes application specific code to perform a custom function of the field device, and wherein the application specific code is downloaded to a memory of the field device separate from the embedded firmware.
A process control system comprising:
- a communications infrastructure;
- a sensor generating sensor data;
- a transmitter coupled to the communications infrastructure and to the sensor, said transmitter configured for receiving the sensor data, said transmitter including:
- a processor;
- and
- a nonvolatile memory storing embedded firmware, said firmware including computer-executable instructions that, when executed by the processor, perform:
- a standard measurement as a function of the received sensor data;
- and
- a runtime interpreter, said interpreter executing application specific code to implement a custom function of the transmitter, wherein the application specific code is downloaded via the communications infrastructure to the memory separate from the embedded firmware.
