Abstract

The present disclosure relates to a safety system having a memory unit configured to store a series of executable instructions. In some embodiments, the executable instructions are grouped into code parts, and each code part is assigned a predefined code value. A processor is configured to execute the series of executable instructions, and to output the predefined code values respectively as the code parts are executed. A program flow monitoring (PFM) unit is configured to respectively receive the predefined code values from the processor, such that the PFM unit generates an error-checking value from the predefined code values. A verification unit is configured to compare the error-checking value to an expected return value to determine whether the series of executable instructions executed properly.
