In FIG. 4, the ToDo list 1020 includes a display of a list ID 1021, a device icon 1022, a work target 1023, a type 1024, and an item/result 1025.

The list ID 1021 is information that uniquely identifies one work target in the ToDo list 1020. In the present embodiment, one ID for the ToDo list 1020 shown in FIG. 4 is referred to as “one work target”. One work target is a maintenance work execution unit, and examples thereof include setting for each field device 19 specified by a device tag, setting for each facility, and setting for each work. The value of the ID 1021 may be numbered or checked so that it does not overlap with other IDs.

The device icon 1022 displays the type of the field device 19 indicated by the type 1024 so that the operator can easily recognize it. For example, the circular icon shown in FIG. 4 indicates that the type of the field device 19 is an input device. Similarly, a square icon indicates an output device, a horizontally long rectangular icon indicates equipment, and a triangular icon indicates work. The device icon 1022 may display, for example, the name of a field device or a photograph, in addition to the illustrated graphic.

The work target 1023 indicates the field device 19, the facility, or the maintenance work to be maintained. For example, when one field device 19 is a work target, a device tag such as “TAG1” that identifies the field device 19 is used. If the equipment or work does not communicate, enter the equipment name or work item. For example, in "Facility 1", the case where the abnormal sound confirmation by the hearing of the operator is set as one work target is shown. In the work item, a maintenance work name for the field device 19 such as “loop check” and “zero adjustment” (zero point adjustment) can be input. Note that work items other than maintenance of field devices, such as cleaning work, may be input to the work items. As a result, it becomes possible to manage the maintenance work of the field device and other work in the same ToDo list.

As the type 1024, it is possible to input whether the field device 19 of the work target in the ToDo list 1020 is an input device or an output device. Further, the type 1024 may indicate that the work target in the ToDo list 1020 is equipment or work that does not communicate.

The change of the display mode may be, for example, the size of the character of the maintenance item, the character color, the character font, the character background filling, the character deletion, the addition of a character such as “Done”, and the like. By changing the display mode of the maintenance item for which the maintenance has been performed and displaying the ToDo list 1020, the worker can easily grasp the progress of the maintenance work. In FIG. 4, the strikeout line indicates that the maintenance item of “loop check” in the work target whose list ID 1021 is “1” has been executed. Further, in the work target with the ID 1021 of “5”, it is indicated that the maintenance items “TAG4” and “TAG5” of the field device for which the loop check has been performed have been executed. As shown in item/result 1025 of FIG. 4, maintenance items include zero adjustment of pressure, stroke test of control valve, change of pressure measurement range, and confirmation of abnormal noise generated from equipment.

By the way, in FIG. 4, as described above, in one work target whose list ID 1021 is “1”, a plurality of maintenance items (“loop check/zero adjustment”) are input to one field device 19. ing. Further, in one work target whose list ID 1021 is “5”, a plurality of maintenance items (“TAG4/TAG5/TAG6”) as a plurality of maintenance items are added to the work of “loop check” input to the work target 1023. The device tag has been entered.

In the maintenance work of the field device 19, it may be more efficient to perform a plurality of maintenance works for the same field device 19 in succession, while the same maintenance work is performed for a plurality of field devices 19 in succession. Sometimes it is more efficient to do so.

In the present embodiment, the list creation unit 111 creates a ToDo list 1020 including a plurality of maintenance items in one work target, and the list display unit 112 displays the created maintenance list to display a plurality of maintenance items.

There is. Therefore, in the present embodiment, it is possible to create the ToDo list 1020 in consideration of the efficiency of maintenance work when performing any of the above maintenance work.

The order of execution of the maintenance target or the maintenance item in the ToDo list 1020 is arbitrary. For example, the list IDs 1021 may be executed in ascending or descending order. In addition, the order may be different from the order of the list ID 1021. The order of execution may be notified to the operator by displaying the ToDo list 1020. For example, the color of the text of the list ID 1021 or the maintenance item may be changed or blinked to notify the operator of the next execution order. Also, the display order of the ToDo list 1020 may be changed. For example, the arrangement order may be sorted by the work target 1023 or the item/result 1025. Further, a plurality of ToDo lists 1020 may be merged into one ToDo list 1020, or one ToDo list 1020 may be divided into a plurality of ToDo lists 1020. Further, the output of the ToDo list 1020 may be made such that output items can be selected.
