摘要
由于传统继电器控制的传输带存在电路复杂、可靠性差、故障诊断与排除困难等缺点,提出了用PLC对传输带控制系统进行设计。介绍了OMRON公司C20P可编程控制器在传输带控制系统中的应用,给出了PLC控制传输带系统的硬件组成和软件设计,其中包括PLC选型、I/O地址分配、I/O端子接线、程序设计和控制原理。
Because of traditional relay control of transmission belt,there are lots of disadvantages which include device complexity, inferior reliability, malfunction analysis and trouble obviation. The paper shows PLC to design the electrical control of transmission belt. The application of C20P series PLC of the Corporation of OMRON in the control system for transmission belt is introduced in this paper. The paper gives the design of hardware and software about the electrical control of transmission belt, which include selecting a model of PLC,distributing address of I/O, wiring diagram of I/O, designing of programmable trapezium and theory of control.
