Abstract: A process control device according to one aspect of the present invention is configured to control an industrial process implemented in a plant. The process control device includes: a virtualizer configured to run over a hardware in lieu of the hardware; and first and second controllers configured to run over the virtualizer and control operations of a plurality of field apparatuses configured to perform at least one of measurement and operation which are required to control the industrial process; an input distributor included in the virtualizer, the input distributor being configured to distribute a signal output from the field apparatus to the first and second controllers; and an output acquirer included in the virtualizer, and the output acquirer being configured to acquire outputs of the first and second controllers, and output any one of the outputs to at least one of the field apparatuses.

Abstract: A maintenance support system include includes: a first storage unit which stores first specification information indicating a specification of a process control system which performs control of an industrial process implemented in a plant; an actual condition information extraction unit configured to extract actual condition information indicating an actual condition for the process control system; and a first comparison unit configured to output first information indicating a result of comparing the first specification information stored in the first storage unit with the actual condition information extracted by the extraction unit.

Abstract: A process control system that controls an industrial process implemented in a plant, may include: a network provided in the plant; a first field device that is connected to the network, the first field device being configured to output one of measurement data, which is obtained by measuring a state quantity in the industrial process, and first simulation data, which simulates the state quantity; a controller that is connected to the network, the controller being configured to perform control in response to one of the measurement data and the first simulation data output from the first field device; and a simulator configured to generate the first simulation data to be output from the first field device.

Abstract: An automatic storage rack is arranged along a route for a stacker crane. The automatic storage rack includes a rack apparatus body, and a plurality of shelves provided in the rack apparatus body. At least one of the shelves includes a base member fixed to the rack apparatus body, a placement member, and a height changing mechanism. The placement member is arranged to have an article placed thereon. The placement member is attached to the base member such that the placement member is movable relative to the placement member. The height changing mechanism is configured to change a height of the placement member relative to the base member when the placement member moves relative to the base member back and forth.
