上位机与PLC的通讯协议 
    HOST Link系统使用HOST Link 通信协议进行通信,上位机具有传送优先权,总是首先发出命令并启动通信,HOST Link 通信单元收到命令交由PLC执行,然后将执行结果返回上位机,两者以帧为单位轮流交换数据。 
2.2 上位机的PLC链接通讯 
    通信时一组传送的数据称为块,它是命令或响应的单位,从上位机发送到HOSTLink 单元的数据称为命令块,相应的,从HOSTLink单元发送到上位机的数据称为响应块。多点通信时,单帧发送的最大数据块为131 个字符,因此当一个数据块含有132 个或更多字符时,要分成两帧或多帧进行发送。多帧发送时中间帧的格式为:正文、FCS、分界符。起始帧、中间帧的长度为131 ,结束帧的长度最多为131 个字符。 
    Omron系列的PLC 通过RS232 口与主机通信有两种方式,第一种是由上位机向PLC 发送初始命令,第二种是由PLC 向上位机发送初始命令[3]。在监测系统中一般采用第一种方式。
