The Relation between IIOT, SCADA and HMI Explained

Globally, in the modern age, we are observing an exciting new wave of technological development, propelled by automation and effective & skilled human understanding. A few exciting and prominent technological concepts that are at the forefront of this rapidly enhancing high-tech world are the Industrial Internet of Things, SCADA System, and an effective Human Machine Interface (HMI).  The functions of these 3 technologies and how they connect to propel a high-tech future can be elaborated on below –


Internet of Things is a system of intelligent computers, devices, and objects that accumulate and share massive amounts of data. This collated data is sent to a central cloud-based service, where it is inculcated with other data and then shared with end users in an effective way.

The Industrial Internet of Things is being implemented across a plethora of sectors, such as electrical industries primarily dealing in semiconductors, cloud computing, and artificial intelligence in electronics. Industry specialists in this field have estimated that allowing automation in most industrial processes will completely mitigate the risk of human lapses in the system.

It is pervasively believed that IIoT is transforming how companies across several industries monitor their business, opening avenues for them to introduce a new age of automation and smart industry solutions across a host of business verticals. Industrial IoT has allowed companies to grow, while simultaneously helping them amplify the economy by cultivating dependable industry services. It encourages a cycle of generating job opportunities, maximising inputs, and boosting revenue.


Supervisory Control and Data Acquisition (SCADA) can be described as a control system architecture that applies the functions of computers, networked data communications, and graphical user interfaces to promote high-level process supervisory management. It additionally utilises extra external tools such as a programmable logic controller (PLC) and discrete PID controllers to regulate the process plant or machinery. The application of SCADA software has also been recognised for the management and operations of project-driven functions in prominent industries.

Human Machine Interface

A Human Machine Interface allows for complex and incomprehensible machine language to be translated and presented in a manner that allows for greater transparency of information, while also making sure that employees can operate and utilise this seemingly complex machinery without any difficulty. It results in various benefits such as improved productivity, increased employee satisfaction & morale, and efficient recording & storing of data.

HMI is a system facilitating human & machine interaction, and is essentially a part of the broader scope of SCADA. Basically, the main goal of an HMI is to present a graphical interface of any functioning machinery that is functioning and sees to it that the machine language is displayed in such a manner that can aid the workforce comprehend the functions involved in this machinery.  Both these phenomena help propel the applicability of the Internet of Things across different industrial sectors.
