We will now be looking at simple data logging using a Click PLC with an Ethernet port. Node-RED will be used to communicate to the controller via Modbus TCP protocol. Information collected will be then stored in an SQLite SQL database. A Raspberry Pi 4 single-board computer will be used for the Node-RED collecting and storing. The update time will be two times a second (500 mSec). This method is ideal for quickly determining how things are operating. https://accautomation.ca/series/node-red-iot-enabling-software/ Analysis or display of the information will be done with a spreadsheet. The spreadsheet will be run on a windows computer. Let’s get started. More information can be obtained at our website. This includes all of the links mentioned in this video. https://accautomation.ca/simple-click-data-logging-node-red/ In this series we started using Node-RED in some of the following ways: Installing the Windows Software https://accautomation.ca/node-red-installing-the-windows-software/ https://youtu.be/xGzH2Hv31WA Modbus RTU / TCP Communication https://accautomation.ca/node-red-modbus-communication/ https://youtu.be/yX1w5vcV6cc User Interface - Dashboards https://accautomation.ca/node-red-user-interface-dashboards/ https://youtu.be/8zAG2wXwGOc SQL Database Log https://accautomation.ca/node-red-sql-database-log-modbus-logging/ https://youtu.be/QHjcNj1S_Mo
