Re: Machine/Enterprise Networks

A tied-together approach does have its advantages but nothing is ever secure as it sounds. It would seem an attack, whether done by a hacker or a virus, could bring anything tied to that network down instead of being compartmentalized in a single area like those of node-based networks.

Machine/Enterprise Networks

Tool_Maker, You make a lot of good points. In most network designs, my understanding is that network traffic is not mixed and is completely separate from external traffic.  When there is a need for exposing the network to the "outside", the security needs obviously grow dramatically. It's interesting that policies, procedures and physical security become as big of issues as the fancy technology protection measures. Thanks for your comments.

Ann, I don't think machine control and entreprise network traffic is mixed any more than is required for specific functions.

The buffer zone/perimeter network is an interesting concept, and at least at first glance looks like a good idea. But Tool_maker's comment makes me wonder about all those connections, too. Sequestering different networks--internal comms versus the manufacturing network where profit-center work is done, like the battalion--seems like a much more secure topology, as well as less crowded. Yet it's been a common topic in DN and elsewhere about all the efforts to bring IT together with manufacturing. Perhaps that needs a rethink.

Why tie the networks together?

I understand the need to tie stuff together internally for inventory control, tracking orders, and a million other reasons. I undrestand the desire to go outside for banking, order placement and a host of other reasons. I do not understand why they ever have to be tied together.

 A million years ago when I was in the military, I was in a mechanized unit. The company commander's vehicle had two radios. One on the company network and one for the battalion. that way neither was cluttered with nonessential chatter. Does that not seem like at least a partial solution to this threat? When everything is linked that brings to mind a person using a megaphone to carry on a conversation and then trying to figure out how to soundproof the room so the conversation remains private.

  Just because we can link everything, does not mean itis the best method.

The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
