Hardware design of automatic feeding system in tank area based on PCS7 software

摘要

The purpose of this paper is to introduce a set of automatic feeding system in the tank area, to achieve a variety of material handling precision control. This paper introduces the composition and function of the system and describes the characteristics and application of PCS7 software in the automatic feeding control system. The system was designed and developed based on Siemens PCS7 software. The programming language used for this project is the SFC programming language. The system's lower computer using the Siemens S7-400 PLC, the function is to achieve the automatic delivery of 10 different materials to 47 metering tanks in 16 different positions of 5 production plants quantitatively and automatically. The system is currently in Zibo Xinhua pharmaceutical five ammonia tank area successfully put into use, run well, and applied for the Zibo City Science and Technology Progress Award.
