Description

  The present invention relates to facility management technology, and more particularly to an alert display technology for displaying an alert for each field device installed in a facility.

  In facility management systems used in facilities such as factories and plants, various data obtained from field devices such as sensors, valve positioners, and flow meters installed in the facility are converted into controllers, I / O modules, fieldbus controllers, and HART. By collecting via a higher-level device such as a communication module, the operation status of the entire facility is managed based on a hierarchical structure including these higher-level devices and field devices.

In such a facility management system, an alert display device that displays alert information acquired from the facility management system on a screen is used to notify an operator of an alert (alarm) generated in each field device.
This alert display device has a function of displaying a list of various alerts generated in any field device designated by the operator on an alert list screen. As a result, the operator can confirm in detail the alert contents and the occurrence status generated in any field device.

  In addition, as an alert display technology in the alert display device, the device symbol of the field device is displayed on the device tree screen using the device symbol corresponding to each device in a tree format according to the hierarchical structure composed of the control device and the field device. A technique for displaying an alert symbol corresponding to the content of an alert generated in the field device at a position adjacent to the field device has been proposed (see, for example, Patent Document 1). Thereby, the alert which generate | occur | produced in each field apparatus distributed by the whole facility can be grasped | ascertained easily on a device tree screen.
