Methods and systems for assessing transmitter electronics in an industrial process control system comprise generating a process condition reference equation signal, a process condition approximation equation signal, and an accuracy output signal. The process condition reference equation signal is generated using a process condition reference equation and process control inputs. The process condition approximation equation signal is generated using a process condition approximation equation that approximates the reference equation using the process control inputs, and approximation equation coefficients based on the approximation equation and the process control inputs. The approximation equation signal is compared to the reference equation signal at a control room workstation such that the industrial process control system can be adjusted. In one embodiment, the approximation equation coefficients are adjusted and transmitted to process transmitter electronics over a control network. In another embodiment, a parameter of the industrial process control system, such as a primary element or transmitter, is adjusted. |
