Abstract
A spinning mill with a master process control computer for at least one group of machines, whereby each machine of the group is provided with its own machine control unit which controls the actuators of the machine (including any auxiliary aggregates allocated to the machine). At least one network is provided for bidirectional communication between the computer and each machine of the group. During the operation of the plant, master control instructions from the process control computer are supplied via the network to the machine control units. Each machine control unit forwards the control instructions to the actuators controlled by the machine control unit, whereby the control instructions, if required, are converted by the machine control unit into control signals which are suitable for the actuators.
