TSN, the Communication Base for a Connected World
www.tttech.com
We all live in a connected world …
3
… and it’s getting more connected all the time
Manufacturing companies are using more and more technology on
their factory floor
Smart devices
More information
Better analytics
All to be more productive and
less wasteful
Circa 1980’s Today Change
Memory 1 Mega Byte 1,000 Mega Byte 1,000X
CPU 1 MIP 10,000 MIPs 10,000X
Network 1 MB 1,000 MB 1,000X
Size 40 ft3 0.04 ft3 1,000X
Cost $1,000,000 > $100 1,000 X
Today the average worker in a modern plant
interacts with over 30 smart devices per day …
in the near future this will grow to 300+ then
3,000+ smart devices per worker
www.tttech.com
There will be soon billions and
billions of connected devices

Everything is Connected …

… but is there really an efficient communication?
And what is needed for it?
Trend #1: Converged
Infrastructure • Communication and control between sub-systems and
machines from different vendors over a common
infrastructure
• Collaboration between machines and between humans
and machines
• Blurring of traditional boundaries between embedded
automotive/automation and enterprise worlds
Trend #2: New Horizontal
Ecosystems • Proprietary vertically integrated systems replaced by open
standard technologies
• Disruption similar to that caused by IP telephony
• Influence of automotive industry driving standardization
of technologies and slashing costs of components
Evolution of Ethernet
Initial 10b2 Ethernet:
CSMA/CD Collisions
“Best effort”, the
reason Ethernet got
a bad reputation
with determinism
Evolution of Ethernet
Full Duplex Switched
Full duplex switching was
a major enhancement.
Additional improvement
by adding priority
queuing, rate shaping
and policing (QoS) – but
still lacking functions to
support a converged or
deterministic networking QoS shares the road, high priority
is faster than lower priority
Deterministic Ethernet:
Safe, Secure, Scalable, Converged
Time-Triggered Ethernet – Converged Best Effort + Critical Traffic
TSN gets the entire
road if needed
IEEE 802.1 TSN allows a
truly converged network
with low jitter and fixed
latency where scheduled
critical traffic gets a
guaranteed bandwidth
and is immune from
affects of best effort traffic
TSN – IEEE 802.1
12
IEEE defines Ethernet standards within 802 working groups
IEEE 802.1 TSN (Time Sensitive Networking) task group aims
to provide deterministic services through IEEE 802 networks, i.e.,
guaranteed packet transport with
bounded latency,
low packet delay variation, and
low packet loss
TSN – Main Characteristics

Major consortia and alliance groups in industrial automation and
automotive are standardizing and conformance testing
for TSN interoperability

Formal Liaison of AVnu and IEEE 802.1
• AVnu Alliance has a formal liaison with IEEE 802.1 Task
Group to collaborate on TSN usage for the industrial and
automotive markets.
• This will help to achieve consistent alignment between
– the group in IEEE 802.1 working on the TSN standards and
– the AVnu Alliance members working on market usage
(industry profiles) and certification testing.

OPC UA – Open Communication
Protocol from OPC Foundation
21
OPC UA provides a vendor agnostic solution to
communicate to any machine and device
Why Converging IoT Networks will
Drive Change in Controls
22
A mix of technologies fulfilling similar demands
OPC UA for plant communication
PROFINET / CC-Link / EtherNet/IP
for process communication
POWERLINK / SERCOS / EtherCAT
for in-machine communication
Separation between different levels
High development/maintenance cost
of multiple, congruent solutions
Multiple communication experts
at machine builder
Gateways needed
A Flat Automation Hierarchy
Enabling IoT Centric Controls
23
OPC UA over TSN: one unified communication for all
infrastructure elements
Direct access to machine data from ERP/MES
Real-time and non-real-time domains integrated
OPC UA provides leading technology of proven security concepts
Learning from the
internet experience:
digital horizontal
platforms and open
innovation win
Deterministic Ethernet incl. TSN for
Motion Control and Large Networks
24
By using TSN-based Deterministic Ethernet we aim to achieve ultra-
low latency with:
Cycle time down to <10µs
Scalability >10,000 nodes connected in real-time
and >1,000 applications sharing the network
Integrated safety & security
Backed by leading industrial
automation vendors committed
to a TSN-based Deterministic
Ethernet controls architecture
Future Controls Architecture:
OPC UA TSN Becoming a Reality
