Create your own framework: Node-red. First steps

Create your own framework: Node-red. First steps

Node-red is a framework thought for an iot solution. The framework is programmed using a graphical  interface. In this post we are going to focus on the first steps a user must know to start a node-red project. If you want to know the basics of Node-red you can go to this post: An introduction to Node-Red   Installation sudo npm install -g –unsafe-perm node-red    Run node-red Now you can go to http://localhost:1880and start editing flows   Create a…

A Conveyor Belt Control System with an Arduino PLC and a Rasberry PI Panel PC HMI

A Conveyor Belt Control System with an Arduino PLC and a Rasberry PI Panel PC HMI

http://www.industrialshields.com Conveyor belts are very common in industry: we can find them in different industries like mining, food & beverage or chemicals.  They are used to deliver heavy materials from one place to another. In this project we will make a control system based on M-Duino PLC hardware that can be controlled through an SCADA / HMI software for food industry. Introduction The application to be developed must ensure that a conveyor belt works properly: Must verify that the conveyor…

Controlling temperature with a got exchanger through a modulating valve in chemical industry

Controlling temperature with a got exchanger through a modulating valve in chemical industry

Introduction In industrial applications, the need to control temperature is usual. A typical element used and designed with this purpose is the hot exchanger, which interchanges two or more fluids with different temperatures.In this post we are going to explain how to implement a temperature control through a modulating valve that will regulate the amount of steam that enters the hot exchanger, in order to heat the chemical process. To fulfill the specified requirements, Opiron electronics has developed a PID algorithm…
