HIGH PERFORMANCE ARCHITECTURE FOR PROCESS TRANSMITTERS

摘要

A process transmitter (200) includes at least one sensor (202) which monitors a process variable, and analog-to-digital (A/D) converter circuitry (204) coupled to the at least one sensor and configured to provide process variable data indicative of process variable values. A digital signal processor (DSP) (210) is coupled to the A/D converter circuitry (204) to receive the process variable data. The DSP comprises a co-processor (215) configured to receive and perform calculations on the process variable data from the A/D converter circuitry (204) to generate output data. Communications circuitry (250, 280) of the process transmitter is configured either to control communication over loop wiring (145) which can be coupled to the process transmitter, or to control wireless communications with the process transmitter. A microprocessor (230), separate from the co-processor of the DSP (210), is coupled between the co-processor (215) and the communications circuitry to control movement of the output data from the DSP to the communications circuitry.
