Well, that sounds fine, but totally unrealistic. You have in an industrial plant thousands of these control devices. Maintaining a password list for all these is just not going to work. So builder Bob will have a default password and Joe the mechanic has one. And you the operator have to know who installed this piece of hardware. In an industrial plant not every button or any pressure valve control needs a password. In fact I say the must not have one.
It is a device for industrial manufacturing. In the past the terminals and switches were accessible to anybody allowed into that area. It is an access problem. The network in a manufacturing plant should be inaccessible from outside. Why is that even news?
I do not understand the logic here. Because other driving habits are dangerous too, the use of cell phones while your driving is OK? You are so wrong. Using the cell phone while your driving is not safe. And it doesn't matter if you are using a headset either. I see it every day and there are studies to prove this. And because people are usually too stupid to make good decisions on their own, they have to be told what not to do. That's why DUI is illegal too, even if there are more things which you shouldn't do while driving. -H
On one of the pictures you can see a Infinion-TPM module. Is that activated on the Mac?
