Claim 0:
1. A method 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 method comprising:
performing simulated control of the machine via the software code on a simulation computer based on a predefined execution pattern, said 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; and
starting, during the simulated control of the machine, a next process, which follows an ended process in the temporal execution order, only after a process in a real time of the simulation computer has ended, the virtual time being set to the starting time of the next process at the start of this next process.
