课程名称：使用西门子S7-1200 PLC设计Node-Red（物联网应用） 课程概述： 本课程介绍了Node-Red这一全球最佳的数据管理和可视化工具。Node-Red近年来在多个行业被广泛接受，成为主要的仪表盘工具。作为IBM开发的开源免费工具，Node-Red具有较高的性价比。课程中，我们将使用西门子S7-1200 PLC与Node-Red进行多种通信方式的搭建，包括直接节点通信、MQTT代理和OPC通信。对于MQTT代理，我们使用Eclipse MQTT代理进行数据传输；而在OPC UA通信中，我们将西门子S7-1200 PLC编程为OPC UA服务器，并展示如何在UA Expert软件中测试OPC UA数据。此外，我们使用ngrok软件将本地数据传输到互联网，并讲解如何通过手机控制MQTT代理，这对于物联网应用非常实用。课程中还涵盖了如何为Node-Red编辑器和仪表盘设置用户名和密码，以提升安全性。数据库管理方面，我们使用Microsoft SQL Server及SQL管理工作室，讲解了SQL数据库的安装及基本操作，包括创建数据库、创建表、插入和更新数据。最后，通过使用功能丰富的仪表盘节点进行数据可视化，使本课程在物联网应用领域中具有很高的实用价值。
Hello Friends ,Node-red is worldwide best tool used for Data management and Data visualization. Nowadays Node-red is also accepted in Many industries as there main dashboard. Node-red is cost effective tool as it is developed by IBM for free open source.In this course Siemens S7-1200 PLC is used for many ways communication to node-red. I have use Direct nod communication , MQQT broker , OPC Communication to get data to and from. For MQQT broker I am using Eclipse MQQT broker.For OPC UA Communication I have Programmed Siemens S7-1200 PLC as OPC UA Server. Also Informed How we can test OPC UA Data in UA expert software. In this we have used ngrok software to transfer our data from localhost to internet.Also explain how we can control our MQQT broker through mobile , which can be directly used for IOT application.Also explain how we can provide Node-red editor and Dashboard username and password and can be used as best security option. For Node-red database management I have used microsoft SQL Server and Microsoft SQL Management Studio.Also explain how to install SQL database and all other function like create database , create Table , insert , update is also explain.For data visualization I have used dashboard node which has wide range of feature. This course will very useful in the field of IOT application.
