Lee, what you have articulated in your article is the vision that resulted in things like the Java programming language. Java was originally intended to be used in smart, embedded devices like home appliances. In fact, some of the early examples used to illustrate this included a smart toaster.
The example you give of the appliance repair scenario is a good one. Of course, it is being used on military systems and has been used in aerospace applications for a while. What is new is the availability of very inexpensive smart control systems. I was working with one, from Cypress Semiconductor, that costs only a dollar in quantity. It is a whole programmable, configurable System on Chip (SoC) with extensive I/O. It also is small and draws little power. I use it as an example, and there are many devices around that fit the bill. What makes it different is the connectivity.
Your comment about the Industrial Internet increasing complexity puzzles me, though. In my opinion, it makes it easier to connect things and automate more processes. I guess you could look at it as making things more complex becuase we can do more. On the other hand, these new things we can do are easier to do than before. Having a standard makes it cheaper and easier to integrate.
I have worked on machines that have self-diagnostics. Sometimes it works, and sometimes it doesn't. The break in the electrical circuit may be in the heater element, or may be the wiring connection at the fuse. The wiring complexity involved to monitor each element in the circuit may be too expensive to justify.
GlennA, a long time ago I worked on a R&D project for a manufacturer that involved developing a self-diagnostic system for their products. All the products had a simular structure. The system that we developed would isolate failures to end effector units or intermediate control units. This did not actually require any more wiring. The attempt was not to get down to the smallest level, but to warn of problems and isolate the area (level) of the problem.
The question that looks to me to still be unanswered is "So where does that economic value come from?" What we got as an explanation was a lame description of the value of a gas gage. Then we get descriptions about being able to make last minute engineering changes much more easily. But we are all aware that those last minute changes are mostly caused by earlier jobs not being done correctly, which certainly includes not having the correct product requirements available for the decision making stages. And, believe it or not, a whole lot of last minute changes are in the physical realm, not in the software realm, and so they require physical corrections, which still take time, no matter how fast the change notice is sent. Possibly making corrections to an assembly robotic sequence may correct some problems, but the parts to be assembled are not quite so quick to change.
IT could be quite refreshing to see a description of exactly where the increase in value would come from that was not based on glittering generalities, or stretched analogies.
What I see is the principles in an industry spreading "sunshine" to encourage investors and placate shareholders by inflating stock values. Are any able to show that it is not the way things really are?
Very interesting article. Tim O'Reilly of O'Reilly Publishing/Media company has additional information regarding the industrial internet. He's tracking the topic via O'Reilly Radar blog. Here's the weblink of all the articles on the Industrial Internet.
mrdon, I'm disappointed the manufacturer did not make their IoT device more secure, but responsibility must fall on the end user as well. It does absolutely no good to put robust security into a device if the end user leaves it in its default configuration. The person who leaves their system defaulted to Admin/password is asking for trouble.
However, do you see the absurdity of having to call an appliance manufacturer for password reset instructions because you forgot the password to your refridgerator?
The next generation of hardware needs to take a different approach. The one we're using now DOES NOT WORK.
I agree totally. I remember watching an online documentary about one of HP's printers being unprotected because the password was defaulted to a disable mode. An IT Security expert had a tough time convincing the HP VP of the security vulnerability of their product. The security expert had all sorts of data based on his research and experimentation with the product to support his findings. The final solution to this security glitch was to have a label in red letters saying, PLEASE SET A PASSWORD TO PRINTER. LOL
Good link, TJ. I was about to say that IoT makes absolute sense, especially based on the success automotive is having with self-diagnostics. But then I read your link about the refrigerator sending out spam. I agree with Mr Don when he says that it's unfortunate how a malicious few can wreck a great idea.
