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.
