Design of Electric Control System in PASSIM Filter Cigarette Maker Based on IPC-PLC

The electric control system in PASSIM filter cigarette maker composed of PLC and logic control circuit board has the shortcomings of poor resistance to disturbance and frequent machine failure,which results in low production efficiency and high material consumption.A new electric control system based on IPC-PLC was designed,wherein IPC was used as a core controller,PLC was used for process control,and the communication among various systems in the maker was carried out by PROFIBUS-DP.Cigarette quality inspection and weight control were fulfilled by EtherCAT industrial Ethernet and TwinCAT real-time system.The improved PASSIM filter cigarette maker ran stably and reliably,detected and rejected defective cigarettes precisely;machine efficiency increased from 90% to more than 95%;material consumption reduced.The level of automation and networking of equipment management and data acquisition were improved.
