1. A fault monitoring system comprising:
a fault logic circuit having a fault logic input and first and second fault logic outputs, wherein the fault logic input is adaptable to be coupled to sensor inputs, and the fault logic circuit is configured to compare a plurality of data values provided by respective sensor inputs to respective fault thresholds, and to provide respective fault signals at the first fault logic output responsive to a fault event in which a respective data value exceeds its respective fault threshold;
a write control circuit having a write control input, a write control output and a reset output, wherein the write control input is coupled to the first fault logic output;
a timer having a timer input and a timer output, wherein the timer input is coupled to the reset output; and
a data register having first and second data register inputs and a data register output, wherein the first data register input is coupled to the write control output, and the second data register input is coupled to the timer output;
wherein the data register is configured to receive fault data that includes an event identifier, a timer value, and a timer expiration indicator.
