【発明の名称】監視制御システムのデータベース整合方式
Document Type and Number:
Japanese Patent JP2877064
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To adjust a database of a supervisory controller with a set information of a non-supervisory controller by providing a means for comparing a read result with the database and using a means for updating the database of the supervisory controller when the comparing result is not matched with each other. SOLUTION: When the set information read from the non-supervisory controller 3 is not matched with the content of the database 2, the database 2 of the supervisory controller 1 is not adjustable with the set information of the non- supervisory controller 3, so that the supervisory controller 1 writes information set in the non-supervisory controller 3 in the database to update the database 2 through an interface 10. The set information of the non-supervisory controller 3 is periodically read to execute this processing, thereby enabling the database 2 of the supervisory controller 1 to be adjustable with the set information of the non-supervisory controller 3.
