DGIOT_OPC通道面向工业控制与工业检测场景,通过零代码或者低代码的方式快速完成项目

OPC软件作为工业自动化领域应用最广泛的软件,深受工业控制人员的喜爱。但也有许多情况下,OPC软件并不能满足实际的使用需求:

使用场景

  • 1.OPC只在内网运行,希望可以将数据传递至外网,随时随地查看
  • 2.OPC数据难以存库
  • 3.希望可以更好展示数据,进行数据分析
  • ...

鉴此,DG-IoT专门提供了基于OPC通讯的OPC接口,以实现OPC数据的简单传输,解决行业痛点。

自动扫描点位

DG-IoT OPC通道与DG-IoT桥接服务工具配合,实现opc转mqtt功能,支持opc指标扫描和读写。

指令集编排

DG-IoTOPC通道将自动处理扫描的点位信息,生成读取指定点位有效信息的指令集,通过该指令集读取OPC数据。

组态交互关联物模型

当OPC采集通道成功采集到OPC数据时,若该产品没有物模型,通道会自动生成与OPC信息对应的物模型。 物模型1.png

当OPC采集通道成功采集到OPC数据时会自动生成组态元素,实时展示当前OPC数据。

在设备管理 -> 点击组态 点击组态.png

数据自动存库

当使用OPC采集通道成功采集数据后,可在产品详情中->物存储中添加TD通道,OPC通道将自动把数据传递给存储数据的TD通道,将数据存入TD时序数据库
