Abstract
A data transmission system with distributed control functionality for machine tools, production machines, and robots, having a plurality of control functional units, has a respectively networked movement control system which controls the operation of the control functional units in complex processes. Information relating to movement control can be interchanged by means of real-time cross-communication between the control functional units. An Ethernet link can be used for real-time cross-communication. The use of the data transmission system for printing machines also represents an advantageous application of the invention.
Claims15
A data transmission system for use in a machine, comprising
- a plurality of drive systems each comprising an associated control functional unit wherein each control functional unit only controls the drive system to which it is associated,
- control computers associated to each drive system linked through a first control network and coupled with said control functional units to perform high level process control;
- a second independent network interconnecting said control functional units for real time cross-communication there between,
- whereby information relating to movement control from any one of said control functional units is transmitted in real time to all of the other of said control functional units.
A data transmission system for use in a printing machine having a distributed control functionality and a networked complex movement control, comprising:
- a plurality of drive systems each having a plurality of drive regulators arranged in a group, wherein all drive regulators arranged in a group are linked by an associated ring network and each drive system comprises an associated control functional unit wherein each control functional unit only controls the drive system to which it is associated;
- a plurality of control computers each coupled through a first control network with an associated control functional unit;
- a second independent network interconnecting said control functional units for real time cross-communication there between,
- whereby information relating to movement control from any one of said control functional units is transmitted in real time to all of the other of said control functional units through said second network.
A data transmission system for use in a machine having a plurality of drive systems, comprising
- a plurality of control functional units each control functional unit being associated to only one drive system,
- a plurality of control computers each control computer being associated to only one drive system and the plurality of control computers being linked through a control network and coupled with said control functional units to perform high level process control;
- an independent Ethernet network interconnecting said control functional units for real time cross-communication there between,
- whereby information relating to movement control from any one of said control functional units is transmitted in real time to all of the other of said control functional units.
A data transmission system for use in a printing machine having a distributed control functionality and a networked complex movement control, comprising:
- a plurality of drive systems each having a plurality of drive regulators arranged in a group, wherein all drive regulators arranged in a group are linked by an associated ring network and each drive system comprises an associated control functional unit wherein each control functional unit only controls the drive system to which it is associated;
- a plurality of control computers each coupled through a control network with an associated control functional unit;
- an independent Ethernet network interconnecting said control functional units for real time cross-communication there between,
- whereby information relating to movement control from any one of said control functional units is transmitted in real time to all of the other of said control functional units through said Ethernet network.
