Abstract: A plant monitoring device (10) includes: an alert output unit (23) that, when an anomaly of a plant (1) is detected, creates alert information including a date and time of occurrence of the anomaly; an alert screen processing unit (251) that displays an alert screen on a display unit (19); and a graph screen processing unit (252) that displays a trend graph screen on the display unit (19). When the alert element displayed in the alert screen is dragged and dropped to the trend graph screen in a state where the alert screen and the trend graph screen are displayed, the graph screen processing unit (252) displays, in the trend graph screen, a graph of input data for a predetermined period including the date and time determined from the operated alert element and displays a highlighting element for highlighting the date and time in the trend graph screen.

Abstract: A control system controls a control object device on the basis of control information using a control device and includes: a conversion unit configured to convert an imaging signal obtained by capturing an image generated on the basis of pre-conversion input information which is input information including the control information to the input information and to output post-conversion input information; and a transmission unit configured to transmit the control information included in the post-conversion input information to the control device.

Abstract: The first aid presentation system comprises: a storage unit that stores one or more pieces of notification information associated with one another from among notification information received from one or more monitoring targets, and one or more pieces of registration information registered by a user and information representing a first aid for the monitoring target that correspond to the notification information; a presentation unit that acquires, from the storage unit, one or more pieces of registration information and a first aid that correspond to notification information associated with specified notification information and that presents the one or more pieces of registration information and the first aid; and a registration unit that newly registers registration information in association with the specified notification information.

Abstract: A first aid presentation system includes a storage unit that stores one piece or a plurality of pieces of alarm master information associated with each alarm issued from one or a plurality of monitoring targets, information representing each first aid associated with each piece of the alarm master information, and information representing a time series relationship between the respective pieces of alarm master information, and a presentation unit that acquires, from the storage unit, and presents the first aid associated with the alarm master information corresponding to a designated alarm and information relating to another piece of the alarm master information having the relationship with the alarm master information.

Abstract: An agent device transmits certain data, which is used for generating display data, of data relating to a plurality of pieces of operation data collected from an instrument to a computation server device. A service broker device relays certain data transmitted from the agent device to the server device. The server device generates display data on the basis of certain data relayed by the service broker device.

Abstract: A remote service system includes a first computer terminal configured to add a first signature to control information representing control content to be applied to a facility and transmit the control information and a second computer terminal configured to cause the control content represented by the control information to be applied to the facility, wherein the first computer terminal and the second computer terminal are connected by a first communication network and wherein the second computer terminal and the facility are connected by a second communication network.

Abstract: A control switching device including an operation input part configured to receive a switching operation as to whether to use a second control execution part configured to carry out different control over a control object than a first control execution part for controlling the control object, and a control switching part to transition to a second control mode causing the second control execution part to control the control object according to an operation indicating use of the second control execution part to stop control of the first control execution part while having the second control execution part control the control object or to have the first control execution part and the second control execution part control the control object, or to transition to a first control mode causing the first control execution part to control the control object according to an operation indicating disuse of the second control execution part.
