Abstract
A method synchronizes first and second simulation systems, each operating in a free running operation thereby exchanging data to run the simulation systems. The method includes: a) providing the first simulation system (PLCSIM) being enabled to run in cycles at a linear speed determined by repeatably setting a scaling factor (s); b) providing the second simulation system (Process Simulate) to run in cycles at different speeds; c) the second simulation system requests at the end of a cycle a virtual time stamp from the first simulation system; d) calculating on the basis of the virtual time stamp a virtual duration time Atand on the basis of the virtual time stamp after completion of the cycle of the second simulation system a virtual duration time At; and e) calculating an update sn+1 for the scaling factor according the most recent scaling factor smultiplied by At/At.
