What is a Wireless Network?
A wireless network is a number of transmitters sending data to a
gateway via wireless access points (WAP)
The communication from the gateway is over an Ethernet network
– DCS/ SCADA using MODBUS TCP
– Laptop/ PC configuration
ISA100 is the wireless standard that Yokogawa believe to be the best
wireless solution

ISA100 - Wireless Networks
ISA100 based wireless architecture offers intelligent
solutions for both difficult to wire applications and
standard applications where easy engineering and the
cost benefits associated with removing cabling
infrastructure are beneficial
Faster Engineering Cycles
Easier FAT including full I/O test
Lower cost intrinsic safety
– No cables, barriers, calculations
Weight saving – important for the ever changing
requirements offshore

ISA100.11a (Physical & Data Link Layer)
Global System have to adopt radio band which can be used in all
over the world.
2.4GHz radio band is known as the ISM band.
The ISM (industrial, scientific and medical) bands were originally
reserved internationally for the use of RF energy for industrial,
scientific and medical purposes other than communications.
This ISM band is available worldwide without licenses for users
Data Link Layer
– 16 channels (time slots)
– Each time slot (10 to 14 msec)
& can transmit 8 PV’s & status
– 250 kbit/sec (HART 1.2 kbit/sec
& FF H1 31.25 kbit/sec)
2.4GHz

High Sensitivity Radio – Improved Technology
ISA100 covers 3x the range of wirelessHART
maintaining the regulatory 10mW / 10dbm output…
– Increased range with reduced errors
– The radio and protocol have a greater sensitivity and
reliability built upon proven technology
Saving power and increasing efficiency
**Empirical test data at reference site

Coexistence & Robustness
Spectrum Management
– Allows specific channels to be
black listed
– If other wireless networks
exist within specific
frequency ranges they can be
avoided
Adaptive channel hopping is
employed

Tunnelling Protocols
Use of a single application layer providing both native
and tunnelling protocol capability for broad usability
ISA100.11a native device protocols allow efficient use
of the bandwidth and provide for longer battery life of
nodes
Tunnelling protocols allow the ISA100.11a network to
carry existing protocols such as Fieldbus Foundation,
HART, Profibus, Modbus, and others.
Allows existing installations to be easily converted to
wireless
Better implementation of specific application types
such as
– Vibration monitoring, gas detection, steam trapping

Seeing harmonics is a vital aspect of application data
analysis, only possible through ISA100

Data Security Requirements
The security mechanisms incorporated in the
ISA100.11a standard were designed to meet the
following requirements and constraints:
Message authenticity ensures that messages received
are originated by an authorized device and have not
been modified by an outside, rogue entity
Guaranteed data confidentiality through state-of the
art encryption
Ensure data integrity of data transferred over the
wireless network
Provide protection against replay and delay attacks, a
vital aspect for industrial applications
- 21 -
Data Security & Communication Flow
Device Provisioning
The key for communication (DL and Session
key) is protected by Master key.
Master key is protected Join key. (Master key is
derived from Join key in join process.)
Join key is installed securely with OOB or
Secured OTA.
To provide secure communication, the trust
(key protection scheme) is chained in the
device lifecycle and managed to keep it.
- 22 Page 22
Security key updating
Each key has a lifetime and is discarded after a period of time.
To keep a continuous secure session between devices, a new
key is installed and the devices switch over to the new key,
before the old one is expired. After the join process distributed
keys from the security manager (i.e., Master , DL and Session
key) are updated and this process maintains the ISA100.11a
system.
The new key is distributed through the wireless network from
the security manager. However, the keys are securely protected
with the Master key. The new keys cannot be leaked only
shared with joined devices and/or security manager.
The lifetime of keys is configurable in the security manager. The
maximum lifetime of the keys is 48.5 days, restricted by the
system parameters

Practical Problems with Self Organising Mesh
Blocking a transmitter path near
to the gateway can redirect
significant traffic through a
single point
Battery life is significantly
reduced in this case
Battery life can already be an
issue due to each point being a
transmitter and a router – and
having to listen for other
transmitters
There are many possible routes
determining the best one or
changing route can take a
considerable time

Duocast Functionality
Duocast (Quote from [ISA100.11a:Specifications])
– Duocast provides support for latency-controlled access to a WAP with a
high probability of first-try success.
– Duocast transactions are defined by this standard only for field devices with
links to two or more infrastructure devices, particularly to backbone routers,
as shown.
One transmitter simultaneously communicates with two Field
Wireless Access Points within the same timeslot for low latency
