    摘要: A distributed digital control system includes a plurality of control modules which are interconnected by a communication link. Each module includes a processor unit for running a control program, and a plurality of system databases which correspond to nodes in the system. Each module further includes a selector such as a Dual Inline Package (DIP) switch for inputting a node number. The program automatically selects the database corresponding to the input node number when the module is powered up. The system preferably utilizes the industry standard LonTalk® protocol, with each database including Standard Network Variable Types (SNVTs) and Standard Configuration Parameter Types (SCPTs) for the respective node. A default database is also stored in each module, which is automatically used by the program if the system databases are not found.

    摘要: A distributed intelligence control system for controlling a cross direction profile characteristic of a traveling sheet, such as paper, during production, includes a scanner for measuring a property of the sheet at a plurality of cross direction locations and producing output signals indicative of the cross direction profile characteristic. A host controller system coupled to receive the output signals from the scanner produces signals representing desired profile information, based on the output signals from the scanner. The system further includes a plurality of actuators, each actuator being operatively associated with a corresponding intelligent actuator controller. A local area network provides a bidirectional communication link (1) between the host controller system and the intelligent actuator controllers and (2) between adjacent intelligent actuator controllers, the network transmitting to the intelligent actuator controllers the desired profile information from the host controller system and transmitting between adjacent intelligent actuator controllers actual actuator state information, the intelligent actuator controllers calculating target actuator positions based upon the transmitted information.
