This is an excerpt from a recent educational article by Pepperl+Fuchs:

Connectivity across all levels is at the heart of Industry 4.0, IIoT, smart factories, and intelligent devices. The rigid, hierarchical automation pyramids with dividing layers are increasingly being replaced by more comprehensive network structures in which individual nodes are linked and exchange data with each other.

In order to realize such networking, the devices must be IIoT-capable. This means that they must be standardized and scalable, capable of interoperability between IT and OT systems, and ensure secure communication. Various communication protocols are available here—such as MQTT, OPC UA, AMQP, and REST API. In our multi-part blog article series, you can find out more about the key features of these IIoT communication protocols and for which use cases they are especially suitable. The third part of this article series is about AMQP.
