Large Scale Motor Group Integrative Management and Control Network System Based on PLC-SCADA under Complex Environment

Abstract

Using advantages of PLC, SCADA, inverter, bus and internet in industrial production, in order to cope with the characteristics of large number of motor, complex sequential logical, high drive control demanding and distributed in different territory, it designs a configuration monitoring system for motor group integrative management and control network system, which uses PPI protocol and USS protocol and fieldbus technology, configuration monitoring technology and network technology, etc. It can realize the effective management of large number of motor driving and control. Due to its function quite similar, S7-200 and S7-300 and MM440 in the paper can be replaced by other kinds of PLC and inverter on the market. So the control scheme proposed by this paper is more practical and universal. Application in textile printing and dyeing institutions multi-cell motor driving, it shows that the designed system can drive and control the motor group with high efficiency and reliable.Keyword:largenumberofmotor;motorgroupnetwork;driveandcontrol;inverter;PLC-SCADA.
