SCADA vs IoT: the role of SCADA systems in Manufacturing's Industry 4.0

Posted by Samuel Walton

We are all witnesses to the sustained rise of the Industrial Internet of Things (IIoT) and the demand to ‘digitise’ within Industry 4.0. Yet legitimate SCADA-based questions, specifically in relation to IoT appear ignored, or at least unanswered. So we ask, “will IoT replace SCADA?” and “can the two concepts be integrated?” SCADA and Distributed Control Systems (DCS) are clearly prevalent automation standards, but as a new tidal wave of data from the IoT surfaces, what role will they play in the factory of the future? 

The Information Value Chain

Posted by Finbar Gallagher

Several years ago I was pitching what would now be called an Industrial Internet of Things (IIoT) solution to the Production Manager of a large manufacturing plant. After describing all the data we could collect, and the metrics we could turn it into, I thought I had done pretty well. What Production Manager wouldn't want our system to get his finger on the pulse of his operation? Instead, his next question floored me:"If I don't do anything with the data your system collects, then it doesn't create any value for me, does it?"

The Amara’s Law and the Anatomy of Business Use Cases in IoT

Posted by Somjit Amrit

In the animated discussion, someone asked a quiz question, “What is Amara’s Law?” It turned out that American Scientist Roy Amara came up with an interesting view and an easy to understand law –“While we overestimate the short term effect of technology, we underestimate the long term impact." I feel in the world of IoT this law is fascinatingly relevant.

How Clustering ensures reliability of IoT Gateway

Posted by Mohit Bhardwaj 

IoT gateways may be the unsung heroes of the Internet of Things world. Without them, there would likely be no expectations of tens of billions of IoT devices coming online in the next few years. In many respects, gateways are the glue that holds many IoT implementations together. They enable real-time analysis of IoT data and link multitudinous connected sensors and devices to the cloud. In addition, gateways act as a bridge between various sensor types and connectivity protocols, while helping to link equipment from an organization’s information technology (IT) and operation technology (OT) departments.

But gateways can also be single points of failure in IoT networks. In a poorly designed system, when a gateway goes down, critical functions stop. Preventing that outcome is possible, however, with an IoT gateway architecture based on the idea of clustering
