This is an excerpt from a recent educational article by DigiKey:

This article begins with a brief look at the transition from the automation pyramid in Industry 3.0 to the automation pillar in Industry 4.0, reviews several options for deploying networks to carry both urgent and non-urgent traffic, and considers how TSN fits in and can be implemented. It then considers how PoE and PoE+ can simplify the powering of sensors, controls, and other devices on the IIoT, and it presents the importance of security, including ISASecure certification and advanced security features like wire-speed access control lists (ACLs) and automatic denial-of-service (DoS) prevention.
