Abstract:
1. A method for collision-free transfer of a production plant from an off mode into an operating mode, the method comprising: simulating operation of the production plant in real-time using the simulation tool parallel to actual operation of the production plant in real-time, said simulation being performed based on simulation data generated from plant operating state information transmitted in real-time from the production plant to the simulation tool; deriving production plant operating state information of connected process sections required for collision-free startup of the production plant from the simulation data of the real-time simulation tool using the simulation tool and storing this information in the simulation tool as restart information; transferring the plant to an off mode; transmitting the restart information from the simulation tool to the production plant as part of a synchronization of simulation tool and production plant; and transferring the production plant from the off mode to the operating mode using the transmitted restart information; wherein the simulation tool is based on a Digital Factory concept.
