  • Patent number: 5914880
    Abstract: A system for controlling a manufacturing system including a plurality of working units is described. Each working unit has an operational tool and a unit controller which controls the corresponding tool. Each unit controller includes a storage device for storing data about the status of multiple working units including its own. A data control device is connected to the storage device and the remainder of the unit controllers. The data control device renews unit status data stored in the storage device with the newest data about the status of the working units including that of its own working unit. Thus, all the unit controllers always have the newest unit status data in common. Each unit controller includes a drive control device for controlling the corresponding tool based on the unit status data stored in the storage device.
