A test specification and fault classification enabling for the first time software-implemented fault injection testing of error handling routines within the automated production systems (aPS) domain in practice, targeting up to 90% of today's control code, which is made up of error handling. A light-weight specification for testing IEC 61131-3 aPS software error handling. A comprehensive classification of aPS's technical process faults. A generally applicable test case template specification for testing the reaction of aPSs to technical process faults. An approach for automatically generating IEC 61131-3 compliant test cases. The results of applying the entire concept to an industrial case study from a leading aPS manufacturer as well as to a lab-size case study especially regarding execution on PLCs. Quality assurance improvement in the aPS domain assessed together with experts representing German machine and plant automation companies, who are export world leaders.
