Abstract: A display control method including selecting an indicator image corresponding to a display attribute which is set for a display area, and performing display control for displaying each alarm corresponding to the display attribute among alarms generated in a plant and also displaying the selected indicator image collectively in the display area.

Abstract: A device maintenance apparatus includes: a comparison target selector configured to select comparison targets of a device information of a device as a maintenance target; and a display configured to display a comparative information generated based on changes in the device information.

Abstract: Provided is a display control method including selecting an indicator image corresponding to a display attribute which is set for a display area, and performing display control for displaying each alarm corresponding to the display attribute among alarms generated in a plant and also displaying the selected indicator image collectively in the display area.

Abstract: A device maintenance apparatus includes a setting operator configured to allow for setting a test pattern, the test pattern being set to define a change of output signals output from a device over time, and an execution operator configured to make the device output the output signals based on the set test pattern.

Abstract: A monitoring control system includes: a safety control device that includes a state monitoring unit that monitors a state of a plant after emergency shut-down of the plant, and a work progress monitoring unit that monitors a work progress after the emergency shut-down of the plant; and a display device that displays, in a case where the emergency shut-down of the plant is performed by the safety control device, an emergency shut-down screen including a monitoring result of the state monitoring unit and a monitoring result of the work progress monitoring unit.

Abstract: A device maintenance apparatus includes: a comparison target selector configured to select comparison targets of a device information of a device as a maintenance target; and a display configured to display a comparative information generated based on changes in the device information.

Abstract: A device maintenance apparatus includes a display configured to display an operator receivable of an operation for causing at least one maintenance item associated with a device of a maintenance target to be executed on the device and prompting information for prompting execution of the at least one maintenance item on the basis of execution information of the at least one maintenance item.

Abstract: A device maintenance apparatus includes a device information storage storing information of a device and one or more maintenance items associated with the information of the device, an acquirer configured to acquire the information of the device, and a display configured to display the acquired information of the device and an operator receivable of an operation for executing, with respect to the device, at least one maintenance item among the one or more maintenance items associated with the acquire information of the device and stored in the device information storage.

Abstract: A device maintenance apparatus includes a setting operator configured to allow for setting a test pattern, the test pattern being set to define a change of output signals output from a device over time, and an execution operator configured to make the device output the output signals based on the set test pattern.
