Claim 7:
8. A simulation computer for computer-aided simulation of operation of a machine working in an automated manner, said machine being controllable during real operation via software code on a programmable logic controller, the simulation computer being configured to perform a method in which:
simulated control of the machine is performed via the software code on the simulation computer based on a predefined execution pattern of processes, the predefined execution pattern defining a temporal execution order of processes executed by the software code, starting times of the processes being based on a virtual time, an execution time comprising a duration of time of each process in the virtual time being set to zero such that process interruptions caused by other processes having higher priorities cannot occur and the temporal execution order of processes executed by the software code is maintained, and said predefined execution pattern corresponding to the real operation of the machine;
wherein, during the simulated control of the machine, a next process, which follows a process in the execution order which has ended, is started only after the process in a real time of the simulation computer has ended; and
wherein the virtual time is set to a starting time of the next process at a start of said next process.
