What exactly are robust software controls? I mean inputs are made or not made, greater than or less than tables are true or false, 4 to 20 algorythm devices provide tuning for modulation, and all that is control voltage. There is no robustness in control systems. There may be duplicate inputs and outputs for redundancy, but there is nothing robust about that.

Robustness comes from operating sides of a system, or operating voltage or heat. That means better pipes, better actuating valve systems, flow controls with durability, better heat exchangers, good freq. drives, and robust construction methods done by the best machinists and welders.

So far all we see is black tape and extension cords.

As one who does those kinds of systems, it means that, if you are actually silly enough to rely on the software to keep the thing from blowing up, then that software better not blue-screen.
