Textile machine control system with prioritized message transmission of machine functions

An apparatus comprising:

• a weaving machine for weaving of free patterns which includes two yarn feedwheels, a yarn winding-on part for each feedwheel, and a variable speed control means for controlling a speed of each said yarn winding-on part;
• and a computerized system including a plurality of units which each control a respective said variable speed control means and which together form a network, the network including connection means to which each said unit is connected for effecting message transmission between said units of the system serially and digitally in the form of different message types, said system including prioritizing means for ranking said message types from the point of view of priority so as to discriminate in the message transmission effected and guarantee a transmission time for a finally transmitted messages of a maximum time of 2.0 ms for at least three different messages representing respective instantaneous signals which are trigger signals, wherein the computerized system has means for storing a weaving pattern and control means responsive to the stored weaving pattern for ascertaining in advance a yarn winding-on requirement which would cause one of acceleration, speed and deceleration of one of the winding-on parts in excess of a predetermined value, and responsive to ascertainment of a requirement which would cause said predetermined value to be exceeded for sending through said connection means in advance of the requirement one of said messages which causes the speed control means to move the winding-on part in advance of the requirement so as to prevent said predetermined value from being exceeded.
