Internet of Things
“Things” refer to any physical object with an IP address can connect/send/receive
data via a network.
Kevin Ashton (British) defined “Internet of Things “ in 1999 at Auto-ID Labs while
working on RFID’s (1989 WWW by Sir Tim Berners-Lee - CERN)

Your facility could be targeted
Your facility might be a victim,
even if not targeted
The most targeted industry is
Manufacturing!
Basics:-

Openness – Open Standard
Where open open standards exist…
Innovation is driven
Broad selection of products and vendors
Longer lifetime than proprietary solutions

20
PROFIBUS UK
Trends Summary
IIoT is in the intersection of IoT and Industrie 4.0
Big Data is moved via OPC UA and stored in the Cloud to be analyzed
Networks are most useful item to support IIoT
Companies are budgeting to implement IIoT
PROFINET of Things supports IIoT through
Data Access
Uptime
Open Standards
IIoT/PROFINET of Things

 Installation in hazardous areas Zone 1, Class 1 Div 1*
 cable length <= 1000m @ 10Mbps full duplex
 Increased Safety: communication and power <= 50 field
devices @500mW
 Intrinsic Safety: communication only
 Topologies: Ring, Line, Star (depends on powering
concept)
 Spur
 Installation in hazardous areas Zone 0, Class 1 Div 1*

The Missing Piece
Today restricted to Controller-Device architectures
Vendor neutral protocol for failsafe applications between controllers / machines needed
Benefits for vendors and users:
PROFIsafe’s black channel approach
accepted by users, vendors and
authorities
Reduced efforts due to reuse of
existing technology
Open technology
Fast market adoption
