The history of IoT in manufacturing began with the invention of the programmable logic controller (PLC) in 1968, which allowed for detailed control of individual elements in the manufacturing chain. In 1975, Honeywell and Yokogawa introduced the world’s first distributed control systems (DCS), which enabled flexible process control throughout a plant. As IT systems roared ahead powered by internet/extranet/intranet connectivity, OT systems quietly (and admittedly more slowly) followed suit as opportunities to use data for automation, information, and control emerged. If IT and personal applications of the internet were a revolution for OT and manufacturing, the IoT has been more of an evolution.
The IoT as we know it today emerged in the early 2000s. By connecting machines that were once isolated and giving them a way to communicate, analyze data and optimize performance, the IoT began to enable a world in which operators could make informed decisions using real-time data. Clearly, a set of factors put some limitations on the pace of growth. These headwinds include the sophistication of both edge computing (e.g. the ability processor embedded in factory machines to run algorithms and store data) as well as cloud computing’s ability to effectively (and securely) manage computation. Connectivity had also created perceptions that only net-new machinery could be eligible for IoT-enhanced operations; for organizations dependent on a reliable fleet of brownfield equipment and machinery, the IoT was simply a sales pitch that had no real-world relevance.
Industry 4.0 is the next step in the evolution of manufacturing, and redefined the expectations held of machines’ ability to connect with each other to create efficiencies and drive growth. Fueled by a need to boost efficiency, become more agile to respond to market unpredictability, and improve quality, manufacturing organizations of all stripes are now embracing Industry 4.0—and reaping the impactful benefits of digital transformation initiatives.
As the capabilities and reliability of the cloud and edge computing matured, and after-market connectivity solutions allowed previous siloed machines to become IoT-ready, organizations recognized that the IoT wasn’t merely a possibility, but that it was a sought-after competitive advantage. With more organizations pursuing IoT-driven solutions increasingly expansive solutions and value, competitors took notice. Industrial companies could see clear examples of the IoT’s transformative impact and benefitted from clearly defined roadmaps to IoT success.
Today, the IoT has come into its own as a must-have part of digital transformation for manufacturers, and most organizations would now view the absence of IoT technology as a significant disadvantage.
