Abstract
A control node has a sequence table and subscribers, with the sequence table having data records each having an identification for an action of a manufacturing sequence associated with the control node, an identification for a subscriber carrying out the action and an identification of a parameter set associated with the action, and wherein each subscriber has a sequence interpreter which is designed to read and to interpret the sequence table, and to initiate the actions associated with the subscriber.
Claims34
A control node having a sequence table and subscribers, the sequence table comprising data records with a respective identification for an action of a manufacturing sequence associated to the control node, an identification for a subscriber executing the action and an identification of a parameter set associated with the action, and each subscriber comprising a sequence interpreter which is designed to read and to interpret the sequence table, and to initiate the action associated with the subscriber.
A control system for executing manufacturing processes comprising control nodes connected to each other via a data communication network, wherein the manufacturing process is divided up into manufacturing sequences comprising actions, the manufacturing sequences to be carried out by the respective control nodes, wherein each control node comprises a sequence table and subscribers, the sequence table comprising data records with a respective identification for an action of a manufacturing sequence associated to the control node, an identification for a subscriber executing the action and an identification of a parameter set associated with the action, and each subscriber comprising a sequence interpreter which is designed to read and to interpret the sequence table, and to initiate the action associated with the subscriber.
A control node having a sequence table and subscribers, the sequence table comprising data records with a respective identification for an action of a manufacturing sequence associated to the control node, an identification for a subscriber executing the action and an identification of a parameter set associated with the action, and each subscriber comprising a sequence interpreter which is designed to read and to interpret the sequence table, and to initiate the actions associated with the subscriber, wherein a subscriber is configured as a synchronization component designed to generate signalling data according to an action associated in the sequence table, the sequence interpreter of at least one further subscriber processing the sequence table on the basis of the signalling data of the synchronization component.
A control system for executing manufacturing processes comprising control nodes connected to each other via a data communication network, wherein the manufacturing process is divided up into manufacturing sequences comprising actions, the manufacturing sequences to be carried out by the respective control nodes and each control node as a subscriber comprises a receiving synchronization component for receiving signalling data from further control nodes as well as a transmitting synchronization component for outputting signalling data to further control nodes.
