單相智能電表(Modbus協議)

在我們日常生活中絕大數用到的電表都是單相的，三相電表主要用於工業用途。今天我們將介紹單相智能電表(Modbus協議)的鏈接案例。

一、使用產品

1. 海創Box智能采集網關
2. 串口服務器 (上海卓嵐 4口 ZLAN5443A)
3. modbus智能電表 (XT 微型RS485單相導軌電表220V DDS5188)

 

 

 

二、產品連接方式

三、產品配置

1. 海創Box智能采集網關
2. 串口服務器(上海卓嵐 4口 ZLAN5443A) 請參考設備廠家提供的說明書以及測試工具
   
3. modbus智能電表(XT 微型RS485單相導軌電表220V DDS5188) 請參考設備廠家提供的說明書
   

四、設備寄存器地址

詳情請見設備說明書

五、項目部署調試

       在桌面打開海創Box智能采集網關可視化開發平台進入可視化編輯器。本次教程需要用到如下節點，在左側節點欄中拖拽出使用

1. inject周期性觸發輸入時間戳或者相應的字符

1. Modbus用於讀取Modbus通信協議設備的數據

1. debug用於調試節點輸出

       配置相應節點后配置界面如下：

節點配置

• inject設置成周期性觸發，主要當觸發流程使用，具體配置如下圖

• Modbus需要設置串口服務器對應設備設置的相應端口以及ip，協議選擇Modbus-TCP,通訊模式選擇Telnet(透傳模式)，該設備值為寄存器，使用功能碼FC4讀取數據，配置相應的寄存器地址和標簽以及數據處理規則即可，配置詳情如下圖

 

 

 

• debug在右側調試窗口輸出調試結果，無需配置

部署調試

按照以上教程配置好流程后，點擊部署，部署成功后程序開始運行，就會在調試窗口輸出相應的結果，調試結果如下

五、示例

       以上教程可以通過拷貝下面代碼實現快速復用，在新建的流程中點擊界面右側菜單欄-導入-剪貼板，在文本框中粘貼下面代碼后點擊確定，即可快速復用。
