Assignee: SCHNEIDER ELECTRIC SYSTEMS USA, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 5:
6. An aggregator communicating with one or more safety PLCs, the aggregator comprising:
a memory configured to store instructions; and
a processor disposed in communication with the memory, wherein the processor, upon execution of the instructions is configured to:
receive an expected soft error rate for one or more types of input/output (I/O) modules over time;
receive respective soft error data that was aggregated by respective one or more safety PLCs based on soft errors detected by I/O modules coupled to the respective one or more safety PLCs;
determine actual soft error rates per I/O module type based on the received soft error data;
predict soft error rates for the one or more safety PLCs per I/O module type;
compare the actual and/or predicted soft error rates to the to the expected soft error rate per I/O module type; and
take 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
wherein the processor, upon execution of the instructions, is further configured to output 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.
