Procedure and an apparatus for the control of a component of a textile machine possessing a plurality of similar work-stations beside one another

A procedure for controlling individual components of a work station in a textile machine having a plurality of the workstations disposed in proximity to each other, the workstation components having individual control devices, said process comprising:

• connecting the components at the workstations to a bus system, wherein the bus system is in turn connected to a central control apparatus;
• setting identifying addresses for the components to a default value;
• recognizing with the central control apparatus that the components have been installed;
• initializing a recognition phase wherein the components are interrogated by the central control apparatus and the default address is converted to a component specific address such that for a given section of the textile machine, the same components have different specific addresses;
• controlling operations relating to the components with the central control apparatus that communicates with selected components through their respective control device in accordance with their respective component specific address;
• and
• establishing an initialization phase prior to connection of the components to the bus system such that any component subsequently connected to the bus system is immediately assigned a default address.

• and
• upon lack of an answer from an individual control device after a specified period of time to a read-request from the central control apparatus, initiating at least one of the following:
• the read-request is sent again to the individual control device;
• the individual control device stops its associated component;
• the component-specific address of the corresponding component is converted to a default address;
• and a fault alarm is initiated.
