Practical Tips and Techniques
Node-RED will be used on the Raspberry Pi 4 to communicate serial Modbus RTU to a Solo process temperature controller and Click PLC using twisted pair RS485. This will be done on the same serial network so the devices will be daisy-chained together on the two wires. We will be reading the PV (present value) … Read more
We will now look at the connection to our SQL database using a spreadsheet application. Previously we used Node-RED to communicate Modbus TCP and RTU to our Click PLC and Solo Temperature Controller. The information collected from the controllers was then put into an SQLite SQL database. Spreadsheets like Excel are great for analysis of … Read more
Node-RED can easily display interactive information to the user or operator using a web browser on your phone, tablet, or computer. Any device that has access to the network in which node-red is running. We will be installing the node-red-dashboard palette. This allows us to create a live data dashboard user interface. (UI) The information … Read more
Node-RED is an enabling software for IoT. (Internet of Things) This means we can communicate to control and read information from industrial equipment. Logging information into databases and analyzing this information is easily achieved. Node-RED provides an efficient and easily implemented control solution. The Click PLUS PLC now has a Node-RED Module that will fit … Read more
We will now be installing the Node-RED software on our Windows 10 computer. Node-RED is a powerful and easy programming tool that will allow you to join together hardware devices, APIs (Application Programming Interface), and online services. This joining of information is part of the smart factory. Internet of Things (IoT), Industrial Internet of Things … Read more
We will now look at the productivity Arduino Ethernet web server that we will implement on our Productivity Open P1AM industrial Arduino controller. This P1AM Web Server Example is based on an example found here. This example uses the productivity open P1AM-ETH shield to create a web server that displays the input values of a … Read more
