Systems and methods for generating models of control systems based on the data emitted by the PLCs of the control system are disclosed. It is initially determined if the data of a PLC is structured data or unstructured data. If the data emitted by the PLC is structured data, a model of the control system is automatically generated based on the structured data from the PLC. If the data is unstructured data, information regarding the assets in the control system is obtained from another data source other than the PLC and a model of the control system is generated based on the received information and the data.
