Backplane control system for spinning machines

A control system for a group of spinning mill machines connected in combination for carrying out coordinated spinning operations, said system comprising:

• a plurality of hierarchy communication levels, a lowest said communication level comprising at least one multiprocessor bus backplane assigned to each of said spinning mill machines, each said bus backplane comprising a plurality of deterministic microprocessors connected thereto for carrying out deterministic tasks associated with said respective spinning mill machine:
• a next higher communication level, said next higher communication level comprising a local bus connecting together said multiprocessor backplanes:
• a common deterministic data communications protocol for said multiprocessor backplanes and said local bus so that multiprocessors of each said backplane and different said backplanes can communicate bi-directionally with said deterministic data communications protocol;
• said local bus coupled to a higher superimposed communication level which includes a host control system for said entire group of spinning mill machines, said local bus and said higher superimposed communication level coupled together through a common network communications protocol.
