What is a SCADA/HMI and how to develop one using JointJS+?
SCADA/HMI systems (Supervisory Control and Data Acquisition/Human-Machine Interfaces), along with P&ID (Piping and Instrumentation Diagram) applications, have become indispensable in modern industries. These systems provide essential functions such as real-time control, data acquisition, and remote monitoring, leading to a revolutionary transformation in industrial automation.
SCADA/HMI systems, used across manufacturing, energy, oil and gas, transportation, and other industries, optimize processes and improve productivity. With P&ID integration, these systems gain precision in control and monitoring complex industrial processes.
With the assistance of diagramming libraries such as JointJS+, front-end developers can programmatically create intelligent and interactive SCADA/HMI interfaces using JavaScript (or TypeScript), significantly improving the efficiency and precision of the development process. JointJS+ simplifies development, enabling businesses to stay at the forefront by delivering exceptional customer experiences and driving innovation in industrial automation.
JointJS+ offers an extensive array of plugins, features, and customization options, enabling the creation of interactive and dynamic SCADA/HMI interfaces seamlessly integrated into web applications. In this demo application, we have utilized foreign objects which enables us to include HTML elements in our SVG elements, to be specific input elements such as checkboxes, sliders, and buttons.
The SCADA/HMI demo application above is written in plain JavaScript, but can be easily rewritten in TypeScript or integrated with a wide range of web application frameworks such as React, Angular, Vue, Svelte, or Salesforce Lightning. To check its source code, start a free 30-day trial of JointJS+.
Integration
Are you interested in designing SCADA/HMI interfaces using TypeScript or popular JavaScript frameworks like React, Vue, Angular, Svelte, or Salesforce Lightning? With JointJS+, integrating SCADA/HMI becomes seamless as it is a framework-agnostic solution. The SCADA/HMI demo application, along with other JointJS and JointJS+ demos, is designed to be flexible and easily integrated with these frameworks, providing you with a pleasant and smooth development experience.
To get you started on your journey, we have prepared examples for the most popular JavaScript frameworks that demonstrate the seamless integration with JointJS+. In this example we will show you how to leverage already mentioned foreignObject support.
TypeScript SCADA/HMI
Welcome to the TypeScript realm! JointJS and JointJS+ come with extensive type definitions, enhancing the SCADA/HMI development experience. While our SCADA/HMI demo is currently crafted with plain JavaScript, the migration to TypeScript is a breeze, offering you the benefits of type safety and improved code maintainability. This guarantees a seamless and enjoyable development process as you create interactive and robust SCADA/HMI interfaces.
React SCADA/HMI
Leverage the joint capabilities of JointJS+ and React to design visually appealing and interactive SCADA/HMI interfaces. React's component-based architecture and efficient rendering complement JointJS+, streamlining the development process for efficient industrial automation interfaces. As mentioned earlier, below is an example of using the foreign objects in React application.
-- CODE language-js --
import { useEffect, useRef } from 'react';
import { dia, util } from '@clientio/rappid';
class ScadaButton extends dia.Element {
defaults() {
return {
type: 'scada.Button',
position: {
x: 0,
y: 0
},
attrs: {
foreignObject: {
width: 'calc(w)',
height: 'calc(h)'
}
}
}
}
preinitialize(...args) {
super.preinitialize(...args);
// To handle events you need to create a custom view for this element
this.markup = util.svg/* xml */`
<foreignObject @selector="foreignObject">
<div
xmlns="http://www.w3.org/1999/xhtml"
class="outer"
>
<div class="inner">
<span>Click this button!</span>
<button>Open valve...</button>
</div>
</div>
</foreignObject>
`
}
}
export const ScadaApplication = () => {
const paperEl = useRef(null);
const graph = useRef();
const paper = useRef();
useEffect(() => {
const namespace = {
ScadaButton
}
graph.current = new dia.Graph({}, { cellNamespace: namespace });
paper.current = new dia.Paper({
model: graph.current,
el: paperEl.current,
frozen: true,
async: true,
width: 500,
height: 500,
cellViewNamespace: namespace
});
const buttonEl = new ScadaButton({
size: {
width: 150,
height: 50
}
});
graph.current.addCell(buttonEl)
paper.current.unfreeze();
return () => {
paper.current.remove();
};
}, []);
return (
<div id= "paper" ref = { paperEl } />
);
}
