摘要:
According to one embodiment, a plant control system includes a station mounting controllers thereon, an engineering device which manages programs, and a device which connects the controllers and the engineering device. The engineering device includes database which stores information on a first variable for allowing data to be shared among programs in each controller and a second variable for allowing data to be shared among programs in the station, the database management part, and a relocate management part which moves the program, and the relocate management part includes a designating module which designates an execution order of programs in a source controller, one or more programs to be moved, a destination controller, and the source controller, a module which moves the program as designated in the designating module, and a changing module which, when the program is moved, moves or copies the first and second variable used in the program.

In a disk drive suspension including a baseplate, a load beam, and a flexure, the suspension comprises a recess formed in one surface of the load beam relative to the thickness thereof, a damping material contained in the recess, and a lid portion superposed on the damping material so as to cover at least a part of the recess. The lid portion is formed of a part of a flexure. The flexure is an example of a suspension constituent member.

A slider tester includes a disk, movable table, table drive mechanism, guide member, etc. A plurality of suspensions are mounted on the movable table. A slider is mounted on each suspension. A guide member can support respective lift tabs of the suspensions. The guide member includes a first guide surface, second guide surface, and opening arranged in a track width direction of the disk. When any of the lift tabs gets into the opening as the movable table moves in the track width direction of the disk, the slider is dropped toward a recording surface of the disk.
