Thanks for your response. Sorry I didn't get the joke.

As promised, here's a "simple" explanation of SCADA, or as simple as I can make it at least. It will probably be rudimentary enough to be controversial, and long enough to be boring. Oh well.

It stands for supervisory control and data acquisition, and if you think that's a weird mouthful, it's because it's old and comes from a time when clicking graphics on a screen was a novel idea, and logging swaths of data with a computer and searching within it and rendering graphs from it was cutting edge. The term is basically relegated to plant, industrial and manufacturing type processes where a bunch of engineering has gone into it. Processes like brewing, water treatment, factories, assembly lines, etc.

Those processes are automated with special computers called PLCs that are basically "robot brains" that control things like (but not limited to) motors, valves, pumps, conveyers, robot arms, all kinds of stuff to manipulate the physical world, and can receive information from sensors like (but not limited to) pressure, speed, flow, weight, on/off, open/closed, temperature, distance, or anything else that someone has built a physical world sensor for. You can put all that stuff together with a program in the PLC and automate practically anything from beer making to zebra counting.

And that's all well and good, but if you want to see what the process is doing (supervise it), or stop it if it's gone off the rails (control), or see what it did last time (data acquisition), you need SCADA. There's special software to build a SCADA system with, and it's mostly special because it needs to talk to the myriads of PLC (and related) gear out there, and until relatively recently, it's been tied to an ancient Windows technology called OLE, meaning if you wanted SCADA in your industrial process, you had to suffer with the rather unindustrial wart of Windows in the middle of it. OP is seeking the industrial Holy Grail of a windowsless process in their plant.

We take it for granted today that we can build an interface in a web browser, and hook it up to control a USB device, all in one day, but 40+ years ago there was Windows 3, serial devices, and no commonly established way to communicate with gear (which OLE kinda solved), or standard design of how interfaces should look or work. Ignition brings all of that old shit into the modern world.

A relatable example you could call "baby SCADA" would be a smart thermostat, if it has an onboard temperature trend graph. The process it controls is your automated home heating and cooling. The smart thermostat can tell you if the AC is running, you can change the target setting that you want the room temperature to go to. And if it has a graph of the temperature for the last 24 hours so you can see that the schedule you set worked, then it's basically a 'lil SCADA.

Cheers.
