Node-RED is an enabling software for IoT. (Internet of Things) This means that we can communicate to control and read information from industrial equipment. Logging of information to databases and analyzing this information is easily achieved. Node-RED provides an efficient and easily implemented control solution.
Node-RED IoT Enabling Software Series
Installing the Software
Modbus RTU / TCP Communication
– Display Information on a user interface, HMI, or dashboard
We will be controlling the Solo Set Value through the local dashboard interface or with the information read from the Click PLC.
– Log information into a database
– View information in the database through spreadsheets such as Excel.
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 (IIoT), Industry 4.0, and Smart Production are just a few of the other labels that have been applied to this type of technology.
Node-RED provides a browser-based flow editor. This provides an easy way to visually see and modifies your program flow. Flows can then be deployed to the runtime in a single click. Node-RED is built on Node.js. This lightweight runtime can be deployed on low-cost hardware (Raspberry Pi ) or cloud services (Microsoft Azure). This has the ability to bring data collection, analysis, and storage closer to the actual device. Real-time edge computing can then be achieved without latency issues.
If you’re like most of my readers, you’re committed to learning about technology. Numbering systems used in PLCs are not difficult to learn and understand. We will walk through the numbering systems used in PLCs. This includes Bits, Decimal, Hexadecimal, ASCII, and Floating Point.
