1794-ACN15并行链接通讯

1、并行通讯解决方案

用FX2N，FX2NC，FX1N，FX和FX2C可编程控制器进行数据传输时，是采用100个辅助继电器和10个数据寄存在 1：1的基础上来完成。FXlS和FXON的数据传输是采用50个辅助继电器和10个数据寄存器进行的。

2、使用方法

当两个FX系列的可编程控制器的主单元分别安装一块通讯模块后，用单根双绞线连接即可，编程时设定主站和从站，应用特殊继电器在两台可编程控制间进行自动的数据传送，很容易实现数据通讯连接。

主站和从站的设定由M8070和M8071设定，另外并行连接有一般和高速两种模式，由M8162的通断识别。

3、通讯实例

在并行通讯系统中，控制要求如下：

①主站点输入X0到X7的ON/OFF状态输出到从站点的Y0到Y7。

②当主站点的计算结果（D0+D2）大于100，从站的Y10通。

从站点的M0到M7的ON/OF状态输出到主站点的Y0到Y7。

从站点中D10的值被用来设置主站点中定时器。
