Abstract
A yarn processing system includes a yarn consuming textile machine and at least one yard feeding device, each having electric drive means and electronic control and/or monitoring means. The yarn processing system includes data transmission paths for mutual transmissions between the control and/or monitoring means wherein each of the control and/or monitoring means contains one communication microprocessor for serial or serial and digital transmission of data representing information types in the form of a communication protocol. The information types differ in ranking with real-time transmission priority of at least the information type of the highest ranking. In each control and/or monitoring device, the communication microprocessor is connected with a stationary radio transmitter/receiver for carrying out the data transmission via wireless transmission paths within a frequency band available for industrial applications, and between the communication microprocessor and the radio transmitter/receiver a radio media access control interface means is provided. Operation of the yarn processing system is controlled and monitored by data radio transmission within a frequency band as available for industrial applications wherein any information of any information type as provided by a communication microprocessor is converted by the radio media access control interface means into a radio message transmitted by said radio transmitter/receiver to at least one other distant radio transmitter/receiver and then is reconverted into said information type for at least one other communication microprocessor.
