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.

Process control device, process control system, and process control method

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.

Adaptive maintenance support and control of a process control system via device specification and actual condition information

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.

Process control system

An engineering device includes a drawing builder for generating a general-purpose part formed by combining functional parts, and a general-purpose part managing section for registering the general-purpose part thus generated in a database and quoting the general-purpose part thus registered in the drawing builder to utilize as a general-purpose part object. The engineering device further includes a reuse section for referring to a general-purpose part object, an operation thereof having been confirmed, within a drawing builder and registers the general-purpose part object in the general-purpose part management section.
