Abstract: An operation monitoring apparatus capable of displaying right click menus varying in configuration from each other according to a select object on an operation-monitoring screen is realized. The operation monitoring apparatus comprises an object file holding means for holding a plurality of individual menu definition files registered under object names, respectively, having menu items defined on an object-by-object basis, in an object displayed on an operation-monitoring screen, the object being a target for display on a right click menu screen, a retrieval means for acquiring information on the object name of the object subjected to right click on the operation-monitoring screen, and retrieving the object file holding means 300, thereby extracting the individual menu definition file registered under the object name, and a screen display means for acquiring information on the individual menu definition file as extracted, and displaying the right click menu screen on the operation-monitoring screen.

Abstract: A manipulation-monitoring device may include a storage unit that stores page image data, the page image data being used for displaying a manipulation-monitoring-page, the manipulation-monitoring-page being displayed on a display unit based on data collected from a control device of a plant, the manipulation-monitoring-page being used for controlling operation of the plant, and a display control unit that controls the display unit to display a pseudo-manipulation-monitoring-page instead of the manipulation-monitoring-page, displaying the pseudo-manipulation-monitoring-page being performed by using the page image data without using data from the control device until data collection from the control device is completed, the pseudo-manipulation-monitoring-page showing a summary of the manipulation-monitoring-page.

Abstract: An operation monitor for performing control operation and monitoring of a plant through an operation monitor screen includes a transparent sheet display section for superposing a transparent sheet and entered information thereon for display on the operation monitor screen and storage sections for retaining an operation monitor screen file, an entered information file, and correspondence information between the operation monitor screen file and the entered information file.

Abstract: The present invention provides a process data collection system characterized by the following points: Two real servers which can access process data are provided. One real server is used as the control server and the other as the standby server. The real control server is set to be accessible to process data. The real standby server stops access to process data and does not collect data that are not used. This minimizes the communication load for accessing process data.

Abstract: There are provided a data processing unit and a data processing method capable of reducing a burden involved in packaging and control, and of presenting multiple types of data blocks having different viewpoints with a simple operation. A correlating means correlates objects with multiple types of data blocks having different viewpoints relative to the objects. A selection screen displaying means displays a selection screen so as to accept selection of the viewpoints relative to the objects. A data presenting means acquires data blocks correlated with the objects in respect of the viewpoint selected on the selection screen via the correlating means, thereby presenting the data blocks.
