下面要给大家介绍的是如何使用海创-IIoT平台快速的采集欧姆龙PLC的数据，我们使用的是CP1E-N20DR-A型号的PLC，采用HOSTLINK协议。

一.选择产品
1、CP1E-N20DR-ACP1E

2、海创Box智能采集网关

3、串口服务器



二.设置PLC串口通讯
在欧姆龙PLC编程软件CX-Programmer里面设置PLC的串口通讯的波特率、数据位、校验位、停止位、单元号和采集协议。



下图为寄存器地址



三.采集数据
在桌面中打开海创-IIoT可视化编辑工具，进入可视化编辑器。本次教程需要用到如下节点，在左侧节点栏中拖拽出使用

1、’定时器周期性触发输入时间戳或者相应的字符



2、HostLink欧姆龙HostLink采集协议



下图为本案例HostLink欧姆龙控件的配置内容



下图为服务器配置内容



3、调试用于调试节点输出



把三个控件用线连接起来组成一个流，点击部署最后的效果如下图所示



四.代码示例
以上教程可以通过拷贝下面代码实现快速复用，在新建的流程中点击界面右侧菜单栏-导入-剪贴板，在文本框中粘贴下面代码后点击确定，即可快速复用
