Abstract

Bei einem Verfahren zum Steuern einer Textilmaschine mit einer Vielzahl von Produktionsstellen, insbesondere Spinnstellen, werden die Produktionsstellen sektionsweise gemeinsam überwacht, wobei jeder Produktionsstelle jeweils eine Produktionsstellenelektronik (12 - 22) zugeordnet wird, mittels jeder Produktionsstellenelektronik (12 - 22) jeweils wenigstens ein Teil der Betriebsfunktionen autonom ausgeführt wird, jeder jeweils mehrere Produktionsstellen umfassenden Sektion eine der Produktionsstellenelektronik übergeordnete Sektionssteuereinheit (24 - 34) zugeordnet wird, den Sektionssteuereinheiten (24 - 34) eine in einer weiteren übergeordneten Hierarchieebene vorgesehene Maschinensteuereinheit (36) zugeordnet wird und die jeweilige Produktionsstellenelektronik (12 - 22) zur autonomen Ausführung einer oder mehrerer der Funktionen ausgelegt wird. Dabei werden die von der Produktionsstellenelektronik erfaßten Signale bei der Produktionsstelle zur Anzeige gebracht. Zudem wird eine entsprechende Textilmaschine beschrieben, bei der an der Produktionsstelle in Verbindung mit der Produktionsstellenelektronik eine Anzeige angeordnet ist.

In a method for controlling a textile machine with a large number of production sites, in particular spinning stations, the production sites are jointly monitored section by section, with each production site being assigned one production site electronics (12-22) by means of each production site electronics (12-22) at least a part of each Operating functions are carried out autonomously, a section control unit (24-34) which is superior to the production site electronics is assigned to each section comprising several production sites, the machine control unit (36) provided in a further higher hierarchical level is assigned to the section control units (24-34) and the respective production site electronics (12 - 22) is designed for the autonomous execution of one or more of the functions. The signals recorded by the production site electronics are displayed at the production site. A corresponding textile machine is also described, in which a display is arranged at the production site in connection with the production site electronics.
