1. A maintenance support system, comprising:
- a first storage unit which stores first specification information including predetermined configurations and settings for devices of a process control system which performs control of an industrial process implemented in a plant, the first specification information being correctable by a user;
an actual condition information extraction unit configured to extract, from the process control system, actual condition information including current configurations and settings for the devices of the process control system;
a first comparison unit configured to compare the first specification information stored in the first storage unit with the actual condition information extracted by the actual condition information extraction unit, the first comparison unit being configured to generate first difference information when there is a difference between the first specification information and the actual condition information, the first difference information including a location in which the difference was generated;
a notification unit configured to notify the user of the first difference information;
a second storage unit which stores second specification information including configurations and settings for the devices of the process control system;
a second comparison unit configured to compare the second specification information stored in the second storage unit with the actual condition information extracted by the actual condition information extraction unit; and
an updating unit configured to update the second storage unit to reflect contents of correction by the user for the first specification information stored in the first storage unit when there is no difference between the first specification information and the actual condition information.

Abstract
A maintenance support system include includes: a first storage unit which stores first specification information indicating a specification of a process control system which performs control of an industrial process implemented in a plant; an actual condition information extraction unit configured to extract actual condition information indicating an actual condition for the process control system; and a first comparison unit configured to output first information indicating a result of comparing the first specification information stored in the first storage unit with the actual condition information extracted by the extraction unit.

18. A maintenance support method, comprising:
-
extracting, from a process control system which performs control of an industrial process implemented in a plant, actual condition information including current configurations and settings for devices of the process control system; comparing first specification information, stored in a first storage unit and including a specification of predetermined configurations and settings of the devices of the process control system, with the actual condition information extracted, the first specification information being correctable by a user; generating first difference information when there is a difference between the first specification information and the actual condition information extracted, the first difference information including a location in which the difference was generated; notifying the user of the first difference information; comparing second specification information, stored in a second storage unit and including a specification of configurations and settings of the devices of the process control system, with the actual condition information extracted; and updating the second storage unit to reflect contents of correction by the user for the first specification information stored in the first storage unit when there is no difference between the first specification information and the actual condition information extracted. - View Dependent Claims (19, 20, 21, 22, 23)
