电磁搅拌器多级分布式计算机控制系统的实现

Realization of Multilevel Distributed Computer Controlled system for Electromagnetic Mixer

本文介绍电磁搅拌器多级分布式计算机控制系统的一种实现,上位机和下位机采用串行联接,下位机以内含式PLC为核心控制多台电磁搅拌器。着重讨论了本系统双字节通信编码与内含式PLC的实现技术。

This paper introduces a method to realize multilevel distributed computer controlled system for electromagnetic mixer. The computers are connected each other by serial ports. Build-in PLC controls four electromagnetic mixers. This paper mainly discusses the two-byte communication coding and build-in PLC realization technique.
