@jonf - it depends (I always hate that answer!)... uP processing can be done for a MUCH simpler protocol within a subnet then it's data (or control) can be translated via a router to/from IPv6. Not every node needs everything.
@jonf - Internet Protocol (IP) is quite energy inefficient for low-power, wireless devices. 6LoWPAN is supposed to address that, but it isn't really its own wireless physical layer, as I understand it.
IOT IIOT is a very interesting concept, but without oversight, it could turn into privacy security mess that you have going on now with internet as it stands now. It was built for communications (cold war survival) and not security. What is in place to prevent the same senerio as the one that is taking place now?. Proactive is better than reactive. Esp in the area of IIoT. Many other issues, but this a simple question within a statement.
@pintilei - IPv4 adress are running out globally, but since the USA originally doled them out, we kept a lot for ourselves and still have some left. Other countries are already using IPv6 because they have no IPv4 addresses left.
And as I will address this week, there is a HUGE issue with the older systems' data collected will not be compatable with other systems. So how do we make sure that a temperature from a Johnson Controls wired sensor will be interpreted the same as a wireless from ACME IoT Inc? (yes ficticious, unless bought by Wile E Coyote)
Microchip has some "how to connect to the internet" type application notes (e.g. AN731). So they are trying to help embedded engineers get onto the internet. Anybody else doing that at that very nitty gritty level?
EmbeddedX - short answer? Buzzword. But there are real concerns that we are now adding many orders of magnitude of new nodes in the network and we need to figure out what to do with them and how to deal with the data, communications, and processing load. So yes this new IoT is real, but there are some who are branding the "old" things - such as ZigBee - as a "new" IoT.
Also Charle as you pointed it out we have so many Wired and Wireless Protocols in the industry for last 40 years or so. And there are many devices using one or more of these protocols.
The question is this: In the world of Internet of thing Should have more Bridge Protocols invented for interoperability or the industry is working on some other IoT communication infratructural mechanisms ?
@EmbedXControls: IMHO, I think this IoT has been growing for many years now. I think that it is just being pointed out as it is about to explode in the sheer volume of devices that will be added in the next few years.
Charles, we have all kinds of Internet of things for last 20 years. So what is really new in this new Terminology of IoT ? Is it that we are adding Internet connectivity capability to small devices or devices we never thought needed internet access. What is this ?
Concern of Data-Overload for Humans: Just because the technology exists, doesn't necessarily mean it will be valued by the people in the culture.Health care reports to Doctors for example. I envision volumes of tedious data streaming to Drs getting overwhelmed and ready to scream!
So if it is going to be "Internet" then does it require HTTP protocol? Does that pretty well exclude all communication like Zigbee that is more like a serial protocol? CAN is listed, but not recognized as an Intranet type protocol
I'm launching a project using dynamic QR codes and GeoMapping to create a History Trail system that small town historical societies will use to create their own trail segments. www.thehistorytrail.org please excuse the glitches, we're just getting started.
@Raja- I'm kind of wondering if it will eventualy be the ease of how it is done. For a SCADA system you had to know what information a device has and pull the information out of it. For IIoT they are generally web based and show web pages. Eventually the IIoT might just be a collection of web pages from devices linked into a loose network of ethernet devices.
@Genius - I, too, am trying to understand the difference between traditional SCADA and the IIoT. Maybe it will have more to do with extracting manufacturing process data for business processes? Or perhaps a broad-based IIoT mentality just makes traditional SCADA easier to implement because hardware, software and process are more likely to be aligned out-of-the box?
So going by the definition that IIoT is mission critical, that is the definition of SCADA (Supervisory Control And Data Aquisition) that I have been doing for years. I question whether IIoT must be mission critical, or just simply serving information to those people that want to see them.
In Industrial Automation much of the IOT from industry seems to come out of the Intelligent Manufacturing Systems Group ideas of the mid to late 90s. We were working on the design of interconnected Industrail systems an information sharing and decision making devices from the mid 90s. What's new to me is the small MCU based sensor work we are doing.
@mike.haley - Please try switching browsers and make sure you have the current Flash downloaded. If that doesn't work, your company is probably blocking the live audio stream. You shouldn't have any trouble listening to teh archived version wihich will be available on this page immediately following the class.
Hi all -Audio is live! If you don't see the audio bar at the top of the screen, please refresh your browser. It may take a couple tries. When you see the audio bar, if it doesn't start automatically, hit the play button. If you experience audio interruptions and are using IE, try using FF or Chrome as your browser. Many people experience issues with IE. Also, make sure your flash player is updated with the current version. Some companies block live audio streams, so if that is the case for your company, the class will be archived on this page immediately following the class and you can listen then. People don't experience any issues with the audio for the archived version.
The streaming audio player will appear at the top of this web page when the show starts at 2 PM Eastern time today. If the audio doesn't start automatically, click on the play button to start it. Note however, that some companies block live audio streams. If when the show starts, the audio bar doesn't appear or you don't hear any audio, try refreshing your browser. If that doesn't work, try using Firefox or Google Chrome as your browser. Some users experience audio interruptions with IE.

You are eligible to earn IEEE Professional Development Hours by attending these courses and participating in the chat function. Additionally, we are no longer using the points system, offering "graduation", or giving grades. The IEEE hours are taking the place of that. There are some important things for you to know about earning the hours. The most important ones are that you need to attend these courses live, you need to attend a minimum of two of them per semester, you need to fill out a course evaluation form within 2 weeks of the end of the class, you need to attend 4 out of the 5 classes per course, and you need to participate in the chat function every day you attend. Please click on the link at the top of this page that says "How do I earn IEEE professional development hours" to read all of these important details and more.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
