基于西门子S7-300PLC装卸机械自控系统设计

摘要

Focuses on the mechanical loading and unloading control system structure, the control requirements of the system during operation, and how to achieve automatic operation of the machine function, using S7-300 PLC program features modular design, designing manual control subroutine and automatic control subroutine and tissue procedures, which greatly improving the efficiency and production safety.%主要介绍了装卸机械控制系统的构成、系统在运行过程中的控制要求、以及如何实现机械自动操作的功能,利用S7-300PLC的功能模块化程序设计思想,设计出手动控制逻辑功能和自动控制逻辑功能及组织块程序,大大提高了工作效率和生产安全性.
