Connectivity Framework 1: Introduction
1 INTRODUCTION
Ubiquitous connectivity is one of the foundational technologies enabling data sharing amongst participating components of an Industrial Internet of Things( IIoT) system.
Connectivity provides the ability to exchange data amongst participants within a functional domain, across functional domains within a system and across systems. The data exchanged may include sensor updates, events, alarms, status changes, commands, and configuration updates. Connectivity is a crosscutting function across the functional domains defined by the Industrial Internet Reference Architecture 1, as shown in Figure 1-1.
