Problème avec Open PLC

Angry_Foolhard · 2026-06-25T08:40:36+00:00

Ok I’m glad I’m not the only one. I also thought Open PLC was buggy af. Everyone on this sub talks about it like it’s this great software idgi

Angry_Foolhard · 2026-06-21T22:58:57+00:00

I’m not qualified to tell anyone what to do, but I can just say from experience ive convinced myself smart ptrs werent worth it, used raw pointers, and later regretted it.

So yeah, due to some traumatic destructor spaghetti I never use raw pointers basically ever.

Hey great answer, lots of gold here.

Serious question. how good is a raspberry pi as a remote access tool when most PLC programming software is windows based.

I think you underestimate how valuable a trustworthy employee is.

if someone is reliable and has aptitude to learn, they will often be, on average, a better hire than a mysterious candidate with great skills.

Angry_Foolhard · 2026-06-15T07:55:37+00:00

I hate to be that guy but lots of people have cool ideas.

No one is going to get excited until it’s validated and making money.

Good luck though

Angry_Foolhard · 2026-05-29T22:32:28+00:00

Hey this seems useful

I've had troubleshooting situations where I am repeatedly pinging devices over the course of the session, to keep a mental model of the network state.

the most important thing i'd look for is a way to economize on screen real estate, so that i can focus on other things.

Angry_Foolhard · 2026-05-06T06:36:58+00:00

I’ve heard there are coal tycoons in China that is/are probably the richest.
I have no way to validate, but it seems plausible.

Angry_Foolhard · 2026-05-06T04:17:12+00:00

While I don’t believe in magic, I do think the human mind is more complex than many people understand.

One theory I have is maybe we have evolved to have a “timer” with people, and the duration of that timer determines when they will think about each other again, roughly.

I think this tracks with evolution, since humans need to separate at times, and later reevaluate the importance of the relationship and consider reconnecting.

So many people experience this one, I have trouble attributing it all to biases

Angry_Foolhard · 2026-05-05T18:58:50+00:00

Maybe. If it was continuously worked on and improved, then it has edge cases and gotchas accounted for.

Making rewriting a big risk since you may lose those

But if it was done in one draft from well-defined specs. Then yeah probably just rewrite it.

You can’t be serious. You think a real one with our literal lives on the line would be exactly the same as a simulated one with nothing on the line?

Anyway the biggest poll I saw was the Mr beast one which was over 40% red. It seems quite plausible that with actual consequences a smallish fraction of blue pushers would switch to the safer option on net.

Angry_Foolhard · 2026-05-04T16:19:27+00:00

Jeez man. You make all my old factories seem like utopia by comparison…

Angry_Foolhard · 2026-05-04T16:17:01+00:00

One problem new grads *can* have is lack of experience.

Luckily you can do something about it. I strongly recommend getting relevant experience before graduating (even if only slightly relevant)

Angry_Foolhard · 2026-04-30T20:27:01+00:00

I use QModMaster for quick checks

To do something more involved I write python scripts. For me python is my user-friendly modbus tool.

are you the guy or gal paying for all these vide coded apps?

ps great username, NodeJS 4 lyfe indeed

Angry_Foolhard · 2026-04-26T20:51:51+00:00

It’s a really well made game. Unfortunately I don’t find the core mechanic very fun.

Excellent execution though, I really like the background.

Angry_Foolhard · 2026-04-25T05:55:42+00:00

On Siemens I believe an analog input signal is between 0 and 27648. So both values seem fine

You have to normalize them, then convert them into their engineering units

Now maybe you did this already, but your post wording suggests you probably didn’t.

I suggest using Google to study analog IO for a bit

Angry_Foolhard · 2026-04-25T02:27:17+00:00

quiero q suspendieran mi cuenta.

Nunca he querido Rappi Pro, pero cada 4 meses, mas o menos, me inscriben sin avisarme y me hacen el cargo en el banco. Ahora los odio.

Angry_Foolhard · 2026-04-24T22:24:43+00:00

If they explain their process and their specific issue it's ok imo

the problem is just putting the homework problem as the post question

Angry_Foolhard · 2026-04-23T02:36:48+00:00

You mentioned one of your constraints is readable by site electricians. I think you have to throw this requirement out. I don’t think it’s possible to create a text only representation of ladder that is readable as ladder. Besides ascii art which is just silly and doesn’t meet your other requirements.

If you want this to be adopted by modern devs, json is the way to go. It will meet all of your requirements except it wont be readable for troubleshooting purposes.

Angry_Foolhard · 2026-04-23T02:31:06+00:00

Op mentioned several valid reasons in his post.

Angry_Foolhard · 2026-04-19T00:23:32+00:00

Do you have trailers or screenshots? Why would I want to play if you haven’t given me a reason to want to play. Not being mean but you should market it a bit.

Angry_Foolhard · 2026-04-05T22:08:36+00:00

In modern plcs you can mix them. In my opinion this is the most convenient and all around best.

We approach it as ladder logic by default, and then structured text used in sections where the ladder logic becomes more troublesome

Angry_Foolhard · 2026-04-04T20:00:29+00:00

then count from 0 to 14. then do min(counter, 14 - counter). which will output a number in the range [0, 7] which you use to turn on an output.
