摘要
本文介绍了一套由工控机与PLC组成的油管静水压试验系统的硬件组成与软件设计。在该系统中工控机通过Host Link协议与PLC进行通信。同时还介绍了Host Link协议的用法与在VB 6.0中的实现工控机与PLC进行Host Link通信的方法,具有一定的实用性。
In this paper,the hardware and software of a tubing hydraulic pressure experiment system composed of industrial personal computer and PLC is introduced.The used protocol to communicate industrial personal computer with PLC is host link This paper also describes the use of the host link and how to achieve the communication of industrial personal computer and PLC using VB 6.0 programming language.The system has significant practical application.
