I should not touch computers today
-
Had a meeting with a new client in the UK, for some short term work getting a little IoT widget functioning the way they'd like. It's a simple widget and they don't have actual coders in house so I went with Arduino. Or tried. So here's me failing live over Anydesk and Teams to get this ridiculous Waveshare board working under Arduino. Turns out it won't. At least the touch panel won't work. Nobody has done it. It requires the ESP-IDF, not Arduino. Wish I would have done more research on this before the meeting. In my SVG stuff my gradients are kind of rendering? But it looks like they stop just after the left edge. I checked through all the drawing routines, including this mess that builds up thousands or tens of thousands of "spans" which are arbitrary length runs of a particular color at a y and x coordinate. I spot checked the spans against my reference implementation, which should have been the last mile before the draws, and in 6000 or so I checked about half dozen across the arrays, and they were all the same. I'm out of moves. Some days it just doesn't pay to get out of bed. :(

Yes, some days I don't even bother to gnaw through the straps... Is there some way to get around the CP restriction against direct contact? We used to be able to directly email our peers, but Chris told me that it became a privacy problem, and had to be discontinued. I have a need for a SCADA solution, and your skills would be valuable in finding a solution, given the need for a IoT approach. Yes, there are companies who do this stuff commercially, but I like to include family members in my solutions, and CP members are family. Any thoughts?

sure. can you discord? I'm honey the codewitch on there. we can exchange contact info on that platform.

Not totally, but restricted to badges (I can still see it).

which kind of SCADA? Depending on brand I could help too

If you don't have Discord... I already have witch'es contact, I can send you an email, once you answer me back, I can connect you both
M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.

That would be great! I'm not sure yet where I want to go with this SCADA thing, but something has to be done. I'm running a solar farm backed by a Tesla Megapack, connected to a highly reactive grid with a trio of diesel generators on it. Twice now we've experienced outages that are completely unexplained because there is no decent metering at the various load points on the campus. I can't diagnose or fix these events without the ability to monitor and record!

I should note that I've not worked with anything explicitly called SCADA, but I've worked in environments where they were basically SCADA, like when I was monitoring potlines with moto 6800s at an Alcoa aluminum smelting facility. I was going to land something using Wago PLC, but then my contact for that project dried up. I don't know what happened to it, so I learned about it a bit, but I haven't used it. I already have thoughts in terms of monitoring, but one thing I'm not is an electrical engineer, particularly with analog circuits and high power circuits. I can do simple discrete digital circuits, so it all depends on what you need from me. I would certainly need someone to be point on the electrical end of things.

SCADA is just an acronym for System Control And Data Acquisition, and the control and reporting are all digital. The actual measurements are made with transducers that digitize key signals that need monitoring. Possibly one of the most useful would be the abilty to capture signal levels in a streaming fashion, but retaining measurements for a set period of time so that, when an event is triggered, it is possible to rewind for a time to see what led up to the event. For instance, I recently had a transformer failure - complete meltdown - in the solar yard. Clear across campus, on the one meter I can access, we recorded a 1600 Amp neutral current two days before the meltdown. That signifies a huge fault in a single phase of the grid, but there's no way to tell where it might have happened. Distributed measuring and recording modules, interconnected and capable of sounding alerts, would make this a whole lot easier! We also control the PV Inverters and diesel generators using a Tesla Site Controller via MODBUS/TCP communications, and Tesla doesn't record any logs of the commands sent or the responses received! Who does that??? I suspect that they actually do keep a record, but won't admit it because of their paranoid secrecy about proprietary systems. Sadly, there's no way to prove that. But if I could find a way to configure a device that can record every bit of traffic on those communications lines, I'd know a lot more about what's really going on!

I looked it up before I responded. It does seem familiar, but I've never actually seen the term before you used it. As far as your project, that sounds interesting. It would be a bit of a learning curve to understand all the moving pieces, but yeah - let's see if one of the senior CPers here can connect us. :)

Barring that, I've sent you a missive on Discord. :-D

From the practical point of view: SCADA is another way to say GUI, the only relevant difference is that SCADAs are usually in undependant hardware and get the data access through a bus and the control unit is a dedicated hardware too. It is like a MVVM approach but in Hardware.
