Control System of 550 Profile Steel Leveler Based on Profibus-DP
Ma Ji · Control Engineering of China · 2007
To make steel straightening machine have better performance,the control system of 550 profile steel leveler is designed.SIEMENS S7-300 PLC is applied as the main station of profibus-DP fieldbus,and 6RA70 SIMOREG DC Master and TP170A touch panel are applied to be the sub station.The control and speed adjusting of the main motor is realized,as well as the adjusting of the rollers.Running result shows that SIMOREG DC MASTER module,compared with the traditional system,has the small size and whole function.Setting a reasonable parameters,the optimal operation can be realized.Profibus-DP fieldbus is a communication system suitable for industrial environment application.SIMOREG DC MASTER,SIMATIC TP170A,S7-300 can make smooth data communication with parameters.
