The Industrial Internet of Things (IIoT) is poised to seep into nearly every part of asset-intensive industries — including power generation. Even with the significant opportunities of IIoT, integrating distributed, intelligent devices into plants brings unique challenges. How do IIoT devices complement the telemetry available from existing automation and control systems? How can my organization prepare to embrace this new wave of technology? These are just a few of the questions facing asset-intensive industries with the arrival of IIoT. To better understand these challenges and opportunities, this paper explores how IIoT devices can complement the existing industrial control systems of power generation facilities.
