Abstract
A distributed control system is provided for an automated data storage library. The library accesses data storage media in response to received commands, and comprises an accessor having a gripper for accessing the data storage media, and an XY system having servo motors for moving the accessor and the gripper. The distributed control system comprises a communication processor node for receiving commands, providing a communication link for the commands. An accessor processor node, which may be located at the accessor, is coupled to the communication processor node, the accessor processor node responsive to the linked commands, operating the gripper and providing move commands. An XY processor node may be provided at the XY system, coupled to the accessor processor node, the XY processor node responsive to the move commands, operating the servo motors. A common bus couples the communication processor node to the accessor processor node, and couples the accessor processor node to the XY processor node. A plurality of accessors may be provided, each with an accessor processor node coupled to the communication processor node.
