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 –

IIoT

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.

SCADA

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.

EFF: No Digital Surveillance of Iranians at the U.S. Border—or Within the U.S.

No Digital Surveillance of Iranians at the U.S. Border—or Within the U.S. Only days into heightened tensions between the United States and Iran, media outlets have published disturbing reports of increased scrutiny of people of Iranian descent at U.S. borders, including in at least one case involving a traveler’s phone. EFF strongly opposes any targeting of people for digital surveillance based on their race, religion, or nationality, at our border and in our interior. And we remind all members of the public to practice surveillance self-defense. Disturbing Reports from the Border On January 5, media outlets reported that more than 60 people of Iranian descent, including U.S. citizens, were held at the border between Canada and Washington state for many hours and questioned about their perceived connections to Iran. U.S. Customs and Border Protection (CBP) denied that it detained or refused entry to Iranians based on their national origin, a claim contested by accounts f

EFF: Corporate Speech Police Are Not the Answer to Online Hate

Corporate Speech Police Are Not the Answer to Online Hate A coalition of civil rights and public interest groups issued recommendations today on policies they believe Internet intermediaries should adopt to try to address hate online. While there’s much of value in these recommendations, EFF does not and cannot support the full document. Because we deeply respect these organizations, the work they do, and the work we often do together; and because we think the discussion over how to support online expression—including ensuring that some voices aren’t drowned out by harassment or threats—is an important one, we want to explain our position. We agree that online speech is not always pretty—sometimes it’s extremely ugly and causes real world harm. The effects of this kind of speech are often disproportionately felt by communities for whom the Internet has also provided invaluable tools to organize, educate, and connect. Systemic discrimination does not disappear and can even be ampl

Living on the (IT) Edge: Schneider Electric at HPE Discover 2018

We’re here at HPE Discover 2018 , proudly sponsoring the event and enjoying a jam-packed few days in Las Vegas. The data center industry has experienced tremendous disruption in the last decade. The fourth Industrial Revolution, with its IT/OT convergence, the proliferation of IoT, and insatiable demand for digital connectivity, is creating the opportunity to push the envelope of performance beyond the obvious and create new business value. And there’s no bigger opportunity right now than at the edge. At the same time, these new paradigms are also driving more complexity: companies today are trying to manage a combination of environments, from large centralized data centers on-premises or in the cloud, regional edge data centers, to local edge data centers. We have more data centers, intertwined across more locations, and with more data, than ever before. All of this adds up to promising opportunities on the horizon for our customers – but an equally daunting number of new challenges
