ISA 100.11A connectivity Technologies in IoT

Introduction 

International Society of Automation.

Designed mainly for large scale industrial complexes and plants.

More than 1 billion devices use ISA 100.11A

ISA 100.11A is designed to support native and tunneled application layers.

Various transport services, including 'reliable', 'best effort', 'real-time' are offered.

network and transport layers are based on TCP or UDP / IPv6.

Data link layer support mesh routing and Frequency hopping.

Physical and MAC layers are based on IEEE 802.15.4

Topologies allowed are :
  • Star/tree
  • Mesh
Permitted network include:
  • Radio link
  • ISA over Ethernet
  • Field buses
 Application Support Layer delivers communications services to user and management processes.

It can pass objects (method, attributes) natively within the ISA 100.11A protocol.

A tunneling mode is available to allow legacy data through the ISA.11A network.

* RD=routing device
* NRD=Non-routing device
*H=Handheld device
*B=backbone device




Features
  • Flexibility
  • Support for multiple protocols
  • Use of open standards
  • Support for multiple applications
  • Reliability (error detection, channel hopping)
  • Determinism (TDMA, QoS support)
  • Security
Security
  • Security is fully built-in to the standard.
  • Authentication and confidentiality services are independently available.
  • A network security manager manages and distributes keys
  • Twin data security steps in each node:
        - data link layer encrypts each hop.
        - Transport layer secures peer-to-peer communications.
