A plurality of real control inputs and real process measurements provided by a real automation system controlling an industrial process are continuously stored continuously storing in a historian database. At the same time, a plurality of forecast control inputs and process measurements provided by a virtual automation system based on a simulation model are continuously stored in a futurian database. Both the past operation of the industrial process up to present time based on data from the historian database and the forecast future operation of the industrial process from the present time onwards based on data from the futurian database are displayed on the operator screen.

Method of monitoring an industrial process

The invention relates to a method and an apparatus for arranging redundancy in a process control system comprising at least one client device, at least one data source and at least one server device providing data transfer between the client device and the data source. The method comprises arranging, for the client device, at least two parallel logical connections for transferring substantially the same data between at least one data source and the client device. At the client device, property information on data units transferred via different logical connections is checked, the client device being provided with predetermined order criteria for the property information. At the client device, property information on parallel data units transferred via different logical connections is compared. Data units delivered via the logical connection having, according to the predetermined order criteria, the best property information are selected for the use of one or more applications processing the data units.
