A cell controlling computer is interfaced to a group of station-level computers through an access machine which stores a database of data that is continually being updated from the station-level computers in response to conditions on machines and industrial process equipment. The access machine communicates with the station-level computers using messages addressed to each respective station. The access machine communicates with the cell controlling computer through database operations messages that allow data to be communicated for many stations at once. During on-line reconfiguration, new data items in the station-level computers can be added to the database in the access machine using other database operations messages.

Database access machine for factory automation network

A disc drive isolation system including a disc drive isolation module is disclosed. The isolation module is disposed in the enclosure and has an outer body and an inner body supported within the outer body with the disc drive mounted within the inner body. The mounting of the inner body within the outer body sequesters the disc drive against vibration and shock applied to the outer body. This arrangement enables almost any disc drive to be operated in an industrial environment independent of the shock and vibration characteristics of the environment.

Disc drive isolation system

A disc drive isolation system including an environment control enclosure and a disc drive isolation module is disclosed. A thermo-electric heat pump is mounted to the enclosure for cooling the interior of the enclosure and a fan circulates air within the enclosure. A humidity sensor controls the heat pump and the fan in response to the sensed humidity of the interior air. First and second temperature sensors control the heat pump andthe disc drive, respectively. The isolation module is disposed in the enclosure and has an outer body and an inner body supported within the outer body with the disc drive mounted within the inner body. The mounting of the inner body within the outer body sequesters the disc drive against vibration and shock applied to the outer body. This arrangement enables almost any disc drive to be operated in an industrial environment independent of the temperature, humidity, cleanliness, shock and vibration characteristics of the environment.
