Productivity PLC Node-RED MQTT

We will be using an MQTT broker in Node-RED to communicate to the productivity PLC clients. MQTT stands for Message Queuing Telemetry Transport. This simple ‘publish and subscribe’ communication protocol does not take too many resources. Constrained devices with low bandwidth are ideal for MQTT. This protocol provides machine-to-machine (M2M) connectivity, perfect for the Internet of Things. (IoT) This protocol is not for remote IO or real-time (deterministic) applications. MQTT is a good solution for applications that move data from hundreds or thousands of machines (sensors) to clients in many networks. We will be installing and programming the AEDES MQTT Broker in Node-RED. A productivity P2000, P1000, and Node-RED will be the clients communicating to the broker. The PLC simulator inputs on each controller will control the outputs on the other controller. This will demonstrate the communication capability for publishing and subscribing to this IoT platform. Let’s get started. More information can be obtained at our website.

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. ACC Automation https://accautomation.ca/
