Abstract:
1. A network for data transmission comprising a process control having programmable controllers respectively including a central processing unit and slave processors assigned to said central processing unit, and a network linking said controllers for data transmission via hub switches and/or busses provided with several terminals and assigned and/or integrated memory array; said hub switches connecting its terminals in pairs while disconnecting them from all other terminals and/or temporarily storing data packets forwarded via the terminals separately and forwarding them to the respectively addressed terminal only when said terminal is available and/or can be made available for data reception; said busses linking together access control units which are controlled by a transmission authority control and via which the respective bus receives data from interface modules linked to the busses; said programmable controllers being respectively assigned to one of said hub switches and/or busses; said hub switch and/or bus having separate terminals for the central processing unit and the slave processors of the assigned controller, thereby enabling each slave processor of a respective controller for exchanging data with an arbitrary controller or a module thereof while circumventing its assigned central processor unit.
