​IIoT is an acronym for Industrial Internet of Things. It is a sub-sector of Internet of Things (IoT) coined by Kevin Ashton in 1999. The difference between the two is that IIoT focuses on the industrial part of
IoT.

In a nutshell:

It’s a network of numerous industrial devices connected by communications technologies resulting in systems that can do the following:

– monitor,
– collect,
– exchange,
– analyze;         

and deliver valuable new insights like never before. This translates into
smarter and faster business decisions for industrial companies.

This new layer is transforming major industries like energy, agriculture, financial services, transportation, healthcare, retail and marketing, to name a few.

It consists of the following (this is not an exhaustive list):

– Internet-connected machinery
  also referred to as
  M2M(Machine to Machine),
-Advanced Analytics Platforms   (processing the data it produces),
– Instruments,
– Networked devices like Cellular VPN         Routers,
– Industrial Applications,
– Environmental Sensors,
– Complex Industrial Robots, etc

The path that led to the creation of the Industrial Internet of Things (IIoT)

->1968:Dick Morley
(American Mechanical Engineer) one of the creators of Programmable Logic Controller (PLC) – an industrial computer control system that monitors the state of input devices to make decisions based on a custom program that control the state of output devices.

->1968: Theodore G Paraskevakos
Greek-American inventor and businessman envisaged Machine-to-Machine (M2M) devices combined telephony with computing which gave way to caller line identification (CallerID).

-> 1983: Ethernet is standardized

->1989: Tim Berners-Lee
creates Hypertext Transfer Protocol (HTTP)

->1992:Transmission Control Protocol TCP/IP allows PLCs to have connectivity

->2002: Jeff Bezos
launches Amazon Web Services and cloud computing starts to take off

->2006:Open Platform Communications (OPC) Unified Architecture (UA) enables secure communications between devices, data sources, and applications.

->2006:Devices started to get smaller, batteries and solar energy became powerful and more affordable.

->2010:Sensors drop in price, enabling them to be put into pretty much anything.

IIoT is driving unprecedented levels of efficiency, productivity, and performance and will have a multi-trillion dollar impact on the world-wide economy.
