Abstract: An information collecting device controls a plant based on process data acquired from controllers and field devices connected to the controllers. The information collecting device includes an arithmetic controller and an update controller. The arithmetic controller collects first information which is engineering information of the plant and second information which is device information from a controller, a field device or a combination of both selected from the controllers and the field devices. The update controller generates third information based on a definition in which the first information and the second information are set in advance, and updates the third information in a storage based on a preset update cycle.
