通讯口已经设置完毕,下面就是如何根据要求将数据发送给变频器。
对FX2系列的PLC与上拉机的通信实现,提出了一种价格低、体积小的接口方案,讨论了其硬件和软件的设计思想,该接口装置与控制室和实验室环境下运行可靠。
关键词:上位机通信接口可编程控制器
PLC作为一种高能的控制装置,在分布式系统中得到了越来越广泛的应用。在这种控制方式中,上位机系统是其中重要的组成部分。PLC可以多种方式如直接采用现有的组态软件与上位监迭机通信,但针对小规模的控制系统,找到一种高能价格比的通信方法,
1通信装置的硬件描述
之间实现通道,可使二者互补功能上的不足,PLC用于控制方面既方便又可靠,而PC机在图形显示、数据处理、打印报表以及中文显示等方面有很强的功能。因此,各PLC制造厂家纷纷开发了适用于本公司的各种型号PLC与PC机通信的接口模块。三菱公司开发的FX-232AW接口模块用于FX2系列PLC与计算机通信。还有与以太网连接的接口模块AJ71E71、与MAP网连接的接口模块AJ71M51-S1、与FAIS MAP网连接的接口模块AJ71M51M1等。不同的通信方式,有着不同的成本价格和不同的适用范围。在此介绍一种通过PC机的RS-232口与PLC进行通信的实现方法。
FX2系列PLC的编程接口采用RS-422标准,而计算机的串行口采用RS-232标准。因此,作为实现PLC计算机通信的接口电路,将RS-422标准转换成RS-232标准。
