Notes
The prevailing trend in Industrial Automation and Control System (IACS) networking is the convergence of
technology, specifically IACS operational technology (OT) with information technology (IT). Converged
Plantwide Ethernet (CPwE) helps to enable IACS network and security technology and OT-IT persona
convergence through the use of standard Ethernet, Internet Protocol (IP), network services, security services,
and EtherNet/IP. A reliable and secure converged plant-wide IACS architecture helps to enable the Industrial
Internet of Things (IIoT).
