Siemens PC-based automation control products are divided into Soft PLC and Slot PL. Soft PLC is divided into basic type and real-time type. They are a running software under Windows NT or 2000 operating system, while Slot PLC is a board-type PLC inserted in the PC. It is divided into Slot 412 and Slot. 416 two. IL70: Siemens Embedded Touch Panel Industrial PC. WinCC: Siemens industrial configuration software. ET200: Remote I / 0 in Siemens S7 system, also called distributed I / 0. PROFBUS: Fieldbus. OPC: Object linking and embedding for process control. The textile production line discussed in this article is a newly developed product of Qingdao Hongda Textile Machinery Co., Ltd.

The company is a well-known enterprise in China's textile machinery industry, and its main products are carding machines, doffing machines, and carding machines. In recent years, with the development of the textile industry, the company has continuously developed new products with high-tech and comparable to well-known foreign products. This production line is the key project of Co., Ltd. in the past two years. It is currently in the stage of optimization and debugging and will be available at the end of this year.

Therefore, when this production line is discussed, the names of the equipment are omitted. Its main process, mainly describes the characteristics of Siemens products in the project, and the author's experience in use. Among them, A is the main equipment. If the equipment stops running, the entire production line stops production. And B, C, D, E and other equipment can be independently run or stopped according to different product process requirements of the textile mill, and B, C, D equipment can run one, or two of the same equipment can run simultaneously.

E devices can run in greater numbers at the same time. In terms of electrical control, it is required to reflect the production status of the production line to the workshop-level and plant-level management in real time, and to archive the production data. At the same time, it is required that the running status of all equipment on the entire production line must be transmitted to an operator station and an engineer station for real-time display, and the process parameter setting of all equipment is completed by the operator station.
