ERROR SOURCE IDENTIFICATION METHODS AND SYSTEMS

A method (500), comprising: coupling a set of sensing circuits to a set of electronic devices; sensing, via the sensing circuits, a set of sensing signals indicative of an operating state of the set of electronic devices; applying logic signal processing to the set of sensing signals via coupling a set of signal processing channels to the set of sensing circuits and providing a set of logically combined sensing signals as a result, wherein the logically combined sensing signals are indicative of whether the operating state of the electronic devices in the set of electronic devices is an expected operating state or an unexpected operating state; coupling the set of logically combined sensing signals to a set of input channels of a fault collection and control unit, FCCU; storing at least one data structure comprising data related to the way in which the set of input channels of the FCCU are coupled to the set of sensing circuits via the set of signal processing channels. In response to at least one combined sensing signal being indicative of an expected operating state of the set of electronic devices, the method comprises: identifying (502) the FCCU input channel from which the at least one combined sensing signal indicative of the unexpected operating state originates; accessing (504, 512, 512) the data stored in the at least one data structure; based on the accessed data, identifying (514) the electronic device producing the unexpected operating status sensing signal; providing (516) an interrupt request signal to the identified electronic device.
