1. A method for providing a virtual sensor in an automation system of an industrial installation, the method comprising:
calculating a dataset using a simulation model, wherein the dataset comprises output values based on a varying of possible measured values of a physical sensor over a predetermined definition area; and
storing the dataset,
wherein the dataset produces a correlation between possible measured values of the physical sensor and the associated output values of the virtual sensor;
receiving, in a processing device of the automation system, a first measured value of the physical sensor that corresponds to a physical parameter of the industrial installation;
providing the dataset in the processing device;
determining, in the processing device, on the basis of the dataset and on the basis of the received first measured value, which output value of the virtual sensor belongs to the received first measured value; and
displaying, on a display apparatus, the determined output value.
