Patent ID: 7110846

Claim:
Yarn processing system, comprising: at least one textile machine, particularly a weaving machine; at least one yarn feeding device operatively associated with the textile machine; at least one peripheral accessory device functionally associated with the yarn feeding device for controlling and/or treating and/or monitoring and/or scanning the yarn, said yarn feeding device and said accessory device defining a yarn path; a computerized control device that is part of said yarn feeding device and which has a signal transmitting connection with the accessory device, the accessory device being provided with at least one electronic component for generating and/or receiving signals either presenting at least one condition or initiating at least one action; a local bus system configured to serially communicate data between said yarn feeding device and said accessory device, said local bus system connecting to and being controlled by said control device that is part of said yarn feeding device so as to operate autonomously with respect to other yarn feeding devices, accessory devices, and local bus systems of other yarn paths; and a main bus system connected with at least one main control device of the textile machine or with a superimposed control device for serial rapid data communication, with the yarn feeding device and control device that is part of said yarn feeding device constituting at least one node of the main bus system, said node comprising at least one interface processor like a gate-way processor; wherein the local bus system operates at a first data transmission rate and the main bus system operates at a second data transmission rate, with the first data transmission rate being slower in comparison to the second data transmission rate.
