Abstract
Mechatronic on-site technicians are responsible for maintenance and thus adequate testing of automated production systems. Hence, they must derive test cases from the IEC 61131-3 control code, which requires systematic testing skills. But despite the industry’s high demand for such skills, testing is not established in mechatronic apprentices’ educational curriculum. For the design of a teaching strategy for mechatronic apprentices on testing, this paper investigates the impact of the IEC 61131-3 language on test case design and evaluation. Comparing Sequential Function Chart (SFC) and Function Block Diagram, a trend towards SFC in apprentices’ self-perceived and real competence is shown.
