10. A supervisory control support equipment according to claim 2, wherein said controlling means discriminates an event where any facility, of said plural n of facilities, should be excluded from a configuration of a system, and

saves in said external storage information which should be transmitted to said any facility according to the procedure of said control when said event occurs.

11. A supervisory control support equipment according to claim 3, wherein said controlling means restores supervisory control information to be held in said storage means with information saved in the said external storage when said storage means is recovered from failure.

12. A supervisory control support equipment according to claim 3, wherein said controlling means gives to a medium used for information interchanging with a specific facility, information corresponding to said specific facility, of information saved in said external storage, when said specific facility, of said plural n of facilities, is recovered or started.

13. A supervisory control support equipment according to claim 3, wherein said controlling means discriminates an event where any facility, of said plural n of facilities, should be excluded from a configuration of a system, and

saves in said external storage information which should be transmitted to said any facility according to the procedure of said control when said event occurs.

14. A supervisory control support equipment according to claim 4, wherein said supplemental processing means is constructed of a module distinct from said plural n of management objects.
