An engineering method for establishing an engineering system includes establishing the engineering system in a virtual system (VS) by performing a communication and permitting an access to the virtual system (VS) via an internet (N), the communication being performed by using a service which is provided via the internet (N), the service being used by a first communication system (10) which is connected to the internet (N), the virtual system (VS) being disposed in the first communication system (10), and the virtual system (VS) virtually implementing the engineering system, and inspecting the engineering system by performing an access to an inspection system (TS) via a virtual private network (N2), the access is performed by a second communication system (20) which is connected to the virtual private network (N2), the inspection system (TS) being disposed in the second communication system (20), and the inspection system (TS) inspecting operations of the engineering system which is established in the virtual system (VS). |
