ABSTRACT:
A communications protocol operable in a multi-processor transmitter environment that facilitates communication between the microprocessors is provided. The transmitter includes a sensor module having a sensor microprocessor and a sensor memory. The sensor module digitizes and compensates sensed process variables. The transmitter also includes an electronics module having an electronics microprocessor wherein the sensor and electronics microprocessors each include individually controllable output pins and individually readable input pins. The sensor and electronics microprocessors are connected by an interface having a bus system. The communications protocol comprises a set of instructions formed into procedures. The procedures include a sensor update procedure; a receive data procedure; a send data procedure; a send command procedure; an indexed read procedure; and a read memory direct procedure.
