Abstract: A monitoring system includes: a sensor configured to generate a sensor signal based on a measured property; a controller configured to communicate with the sensor; and a communication channel electrically coupled to the sensor and the controller for carrying electrical communications therebetween. The sensor includes a transmitter configured to transmit an electrical signal on the communication channel to the controller. The controller includes a processing circuit configured to receive the electrical signal, measure an actual signal function response of the electrical signal, correlate the actual signal function response with a reference signal function response to generate a correlation value, compare the correlation value and a correlation threshold to produce a comparison result, and detect a fault based on the comparison result indicating that the correlation value satisfies the correlation threshold.

Abstract: An error diagnosis circuit includes a signal input for connection to a communication interface, configured to receive a first instruction and a second instruction for a device. A circuit is configured to compare the first instruction and the second instruction and to output an error signal if the first instruction and the second instruction differ from one another.
