A diagnostic system is provided and includes a plurality of processors configured to receive data acquired by a sensor. A first processor can execute a safety function that determines a plurality of sensor measurement from the received data, compares selected sensor measurements to predetermined alarm set points, and determines a safety function output for the selected sensor measurements based upon the sensor measurement comparison. A second processor can determine a shadow function output corresponding to the safety function outputs during different respective portions a diagnostic interval. The shadow function output can be configured to replicate the safety function output under conditions where the safety function output is free from error. A third processor can be configured to validate the safety function output by comparing the safety function output to its corresponding shadow function output and outputting a condition based upon the validation comparison.
