Monitoring and control of the cop size is handled by the FM 350-2 counter module, which receives its information from the sensors on the machine.
Operation and display of operating states and recipe management for the machine are performed centrally on a graphical SIMATIC OP27 operator panel, which is connected to the SIMATIC S7-300 system over the internal SIMATIC MPI bus.
Also integrated in the SIMATIC S7-300 is an interface module for the communication network, which is based on the PROFIBUS DP protocol. The PROFIBUS DP bus connects the automation components, such as the drive controller, PLC and display unit, handles communication with the control room and other parts of the machine such as the flyer or winder, and interacts with the transport system and the doffer.
A 1LA7 variable-speed asynchronous motor is used to drive the complete machine. Power is fed to the drive from a vector-controlled SIMOVERT MICROMASTER converter.
