James Bond, the machinist

The levels of protection on the "blocks" raises a big question. How rampant is design theft or tampering on the assembly line? Or is this specifically for keeping the same revision current across the design chain?

It's exciting to think that corporate espionage tactics are at play somewhere. A James Bond style thief, under the guise of a machine operator, houses a micro computer in his jacket. When no one is looking, he copies the memory card with a card reader in his sleeve. The process a mere five seconds. Completed, and in a magicians like grace, he turns puts the original card into the production machine. No one ever knew.

Sounds fun.

The company that I formerly worked for manufactured equipment with the majority of the machines going to China.  We dared not to ship any machines with unlocked PLC programs, as the IP theft stories were not just rumors....

Even if the chips are locked, you are only delaying theft marginally. De-capping chips is a fairly easy, practiced, and documented procedure for getting at the data. If it is worth it to a person, they will go through great lengths to obtain the data.

It's a sad state of affairs.

It's amazing how Moore's Law is transforming the benefits of advanced automation control.  A next generation line of controllers from Siemens basically offers high performance, enhanced security and the ability to integrate add-on applications such as safety within the framework of the single controller.  More processing power=greater flexibility for automation engineers to implement advanced solutions. It will be interesting to see moving ahead what types of additional applications (condition monitoring, for example) end up becoming widely implemented because of these continuing increases in fundamental processing power.

Latest Analysis
If you’ve noticed the recent news about electric cars and batteries, then it’s easy to wonder about the continuing wisdom behind public subsidies for EVs.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
A group of collaborators wants to recast MacGyver or a show similar to it with a female protagonist as part “The Next MacGyver” competition, in order to get young girls interested in STEM fields.
Biomimicry and 3D printing have come together in new swarming ant and butterfly robots that act very much like their insect counterparts, the inventions of German robotics firm Festo.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
