Abstract: Control software of a manufacturing system is usually designed separated from the real plant or its simulation. Undesired behavior can occur after transferring software to the controller. At best, errors are recognized when starting-up, but there can exist failures that occur rarely and seemingly randomly during operation phase. This problem is of high significance, since the complexity of automated systems rises. Hence, control software bugs should be considered in early project phase. The approach presents an integrated framework that facilitates virtual start-up of a plant. It applies formal methods to simulate and even verify control software. This eases control software design and reduces plant downtimes.
