Bridging OT and IT with 6TiSCH

Jane A — Thu, 23 Apr 2015 08:15:40 +0000

Timeslotted Channel Hopping (TSCH), via IEEE 802.15.4e, is an emerging standard in industrial automation and process control (via Wireless HART and ISA 100.11a) that defines a communication schedule between neighbor nodes in Low-power and Lossy Networks (LLNs). In an effort to bridge the worlds of operational technology (OT) with information technology (IT), the 6TSCH working group has been established to define how to use IPv6 over the 15.4e.

Tune into the Right Media Layer

Although they are often named the same, the media layer of IoT networking consists of two separate parts: the radio to transmit the data and the protocol to exchange the data with the receiver. Important for many reasons including updatability. While the hardware can be in place for long periods of time, you can expect protocols to change every few years as exemplified by the 802.15.4 standard which is currently on version m.

Watch this video (or read the transcript) to hear Brandon Harris explain how to tune power consumption, bandwidth, range and cost to get the right sensor for your IoT application.

Episode 7

Meet IoT’s three layers of protocols… the media layer, otherwise known as the physical layer or radio, the network layer and the application layer. Important because they make up the network stack that transports data from the sensor to the cloud. Important because they are standardized.

The Connected Sensor – What it is and how it Scales

Episode 3

Sensors from the M2M world are evolving into connected sensors for IoT. Same sensor tech but now the sensor needs to communicate outside of a local and often proprietary network. Goodbye 35 year-old Modbus, used in SCADA of yesteryear and hello layered communication, needed in the Internet of Things to onboard billions of sensors.

Listen to this podcast (or read the transcript) with Mike Fahrion as he explains not only the anatomy of today’s connected sensor, but also why we’re moving to a layered communication stack
