Today the common practice of industrial automation is characterized by the following: generally the testing of control algorithms starts only when you run the software on a new facility. As a result the testing of the algorithm is postponed until the start-and-adjustment works begin. The readiness of the algorithm up to this moment is unknown. In the article the concept of virtual plant (VP) was put forward to reduce the risks. To ensure that the control algorithm satisfies necessary requirements the model checking verification method is used.
