【Abstract】 For the process of cold bed area in 140 seamless production line, and the 6SE70 converter is the driving device, PLC 300 is the controlling center. According to the agreement PROFIBUS, the communication between the PLC AND 6SE70 is realized. After the cold bed controlling system is applied, the unit operates stably, and reliably, the electricity can be saved highly, and requirement of the production process can be met.更多还原
