METHOD AND ASSEMBLY FOR MONITORING OR CONTROLLING A MACHINE

To monitor or control a machine, current operating signals are captured continuously, and a current operating state is measured continuously. On the basis of the captured operating, a simulated operating state is determined continuously by a concurrent simulator. In addition, upon detection of a difference between the simulated operating state and the measured operating state, a difference pattern that quantifies the deviation or a change in the measured operating state is compared with a plurality of specified difference types which are characteristic of a modification of the machine or a machine operation, and each of the difference types is assigned a difference-type-specific simulator variant. Depending on the result of the comparison, one of the difference types is then selected. On the basis of the simulator variant assigned to the selected deviation type, the concurrent simulator is adapted, and the machine is monitored or controlled using the adapted concurrent simulator.
