Abstract
A method for computer-supported simulation of operation of a machine working in an automated manner, the machine being controllable during real operation via software on a programmable logic controller, wherein simulated control of the machine via software on a simulation computer is performed based on a predefined execution pattern, where the temporal execution sequence of processes executed by the software code and starting time points of processes are defined based on a virtual time and the execution time point of each process is set to zero in the virtual time in the predefined execution pattern, and during the simulation, the next process, which follows an ended process according to the execution sequence, is not started until a process in the real time of the simulation computer has ended, and where the virtual time is set to the starting time point of this next process when the next process is started.
