Simple Click PLC Data Logging

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.

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.

There are several reasons why we are using Node-RED. Here are just a few.
- Built on top of the most dependable programming language JavaScript.
- JavaScript is flexible and easy to work with on web browsers, server-side, IoT, IIoT projects, and more.
- Visual flow type interface making programming easy.
- Node will allow JavaScript code to run directly on a computer.
- Node-RED is a free, open-source logic engine.
- Connect to PLC, PAC, Temperature Controllers, Process Controllers using standard protocols.
- Save and read from databases
- Easily make the Internet of Things (IoT, IIoT) industrial solutions.

Node-RED provides the ability for you to quickly create custom control solutions.
