Very interesting discussion.

I am too, not a Luddite, neither am I a "Victorian" like Varley. In my humble opinion, the brains and experience have been dropped from the equation. In my experience, and line of work, there are too many Gizmo Geniuses out there who haven't a clue about the operational requirements of systems. Yes, I am certainly curmudgeonly on this issue!

One claim for a reheater fan - Fancy touch screen system, checked set-points, alarms, shut down criteria. "Can I see the operational curve for the fan, please".

Operational temperature 400F by design, operational temperature touch screen system 400C!

Oops! Creeping, cracking of the material and finally, catastrophic failure.

Its all down to the details and, every day, there are less of us and more of them!

At least, in our time, with analogic, hardwired systems and only "fancy" digital add-ons, we had to learn the basics of control and protection.

Now you download an RS catalogue, drool a bit and choose a "plug and play" component. None of that full system integration!

;-(

Rgds.
