Claim 0:
1. A method for managing soft errors associated with one or more safety programmable logic controllers (PLCs), the method comprising:
receiving an expected soft error rate for one or more types of input/output (I/O) modules over time;
receiving respective soft error data that was aggregated by respective safety PLCs of the one or more safety PLCs based on soft errors detected by I/O modules coupled to the respective safety PLCs;
determining actual soft error rates per I/O module type based on the received soft error data;
predicting soft error rates for the one or more safety PLCs per I/O module type;
comparing the actual and/or predicted soft error rates to the expected soft error rate per I/O module type;
taking one or more actions in response to a threshold deviation between the actual and/or predicted soft error rates relative to the expected soft error rate for the corresponding I/O module type; and
outputting a visual display of the actual and/or predicted soft error rates, and one or more ranges of deviation for determining when the threshold deviation is reached, wherein the one or more ranges are based on the aggregated amount of soft errors per I/O module type over an expected lifetime for an I/O module of the same type.
