Process control in the textile field

摘要

A spinning mill having a process control computer for at least one group of machines, each machine of the group being provided with its own control which controls the actuator system of the machine (together with any possible auxiliary assemblies assigned to this machine). At least one network for the bidirectional communication between the computer and each machine of the group is provided. Control instructions from the process control computer are directed during the operation of the system to the machine controls via the network. Each machine control passes on the control instructions to the actuator system controlled by this control, the control instructions being converted, if necessary, by the machine control into control signals suitable for the actuator system.
