Are these /g/ or /diy/?

Programming is /g/ but tradie work is /diy/.

Programming is /diy/. /g/ is for mindless consuming.

This is the guy. Buy /diy/ is a slow board

>>105711755
>/g/ is for mindless consuming

PLC programming is one of the most stable computer-related jobs but it's also one of the most depressing.

>>105711937
>depressing
How so?

>>105711755
Fuck off we’re full

>>105711733 (OP)
Do you code them in ladder logic or whatever weird c derivative they use

>>105712107
Ladder is extremely approachable and easy to monitor. It's also very slow and leads to massive spaghetti.

Pros use Structured Text.

>>105711945
Because you're doing something useful to society and not making addiction algorithms for youtube.

>>105711945
The tooling makes me wanna kms

>>105712168
But if you use structured the electricians coming in after you can't read it

oh hai what's going on here guise

>>105711733 (OP)
How do you get into this? I need a jerb and the regular dev market is completely fucked and will likely never recover due to AI and endless jeets.

I haven't heard about there being any jeets in industrial control systems and the like yet....

>>105711733 (OP)
I still don't understand the usecase of these in 2025. It's gotta be a cost, boomer thing.

Unfortunately most of this shit is locked behind a license. Plus the hardware is extremely expensive. If you want a job they want you to have a degree and some real world experience.

>>105716707
A reliable real time operating system with generic I/O and a centralized control interface is pretty much the most utilized computer application where actual things in the real world are done. Any sensor or actuator can be controlled by a PLC. You cannot control 100 solenoids with USB.

>>105711937
What do you need for it? Some cert or do they usually expect formal schooling?

>>105716867
Ya you can, but you wouldn't anyway. What is the use case of a PLC when cheap ass MCs exist?

>>105717646
Guess what's inside?
The answer might shock you.

>>105717758
A non free shitware platform running poorly designed programming languages. Microcontrollers won. I can't believe anyone actually defends this shit unless they're a giga boomer or Simatic salesperson or some shit.

Sir, that's a paper shredder
>t. PLC knower

>>105714906
best way probably is go to a technical school and learn some sort of electrical / industrial technician/engineer. or apply at a systems integrator as something less skilled and try and hope to work your way up to controls.

jeets need not apply ty

PLCs are designed to work in rugged environments constantly for decades and run safety logic without failure. The machines that they may be running can be worth millions of dollars and cannot afford downtime. As much as I love micro-controllers, they would not be able to last and are not safety rated, which make them cheaper.

That's the ideal case

>>105717990
Could PLCs have prevented the 2003 blackout or therac-25 overdoses?

>>105711733 (OP)
you won't be able to afford a siemens one for diy stuff at home, you need to get a knock off compatible one

>>105713935
kek

>>105721784
>therac-25 overdoses
that was because of a programming oversight, which could happen just as easily with a PLC

>>105721784
>>105718100

probably not cause id like to think people didn't account for these issues. theyre just computers that need these scenarios coded

PLCs arent that different from regular computers. its really just the hardware itself is designed to be extremely reliable, used in rough environments, make online edits, but mostly certified for industrial and safety use.

Id love to have open source alternatives. i think there is some cheap open source stuff which can work for smaller solutions. A lot of companies dont want to risk a raspberry pi failing and causing tons of downtime, or killing someone

>>105713770
Call it job security.

>>105712863
yes, it's absolute shit, from siemens to mitsubishi. it doesn't help at all that these suits only work on windows.

>>105717646
Any modern PLC runs on a cheap-ass MCU internally. The cost is for various safety/reliability validation and certification, an ecosystem of expansion modules, bloated development software, documentation and frustratingly slow technical support.

There is software that allows you to make an Arduino or a Raspberry Pi into a PLC, and that's actually a good way to get acquainted with ladder logic and other PLC programming bullshit, but nobody's going to let you put that in a nuclear power plant.

>>105711733 (OP)
I would say /diy/ because PLCs are normally associated with serious industries, and /diy/ is a board for people who get something done, while /g/ is a consoomer board. Furthermore, you don't use regular programming languages to program those, but rather custom logic-based languages like ladder or scl, and judging by my experience with those, it would probably mindbroke most vir/g/ins very fast.

>>105716966
They're often used in pretty nasty industrial environments. It's for protection.

I'm about to apply to a position for siemens and beckhoff hardware. but i want to avoid siemens because of TIA-Portal

>>105711733 (OP)
/diy/? Are you trying to diy a semiconductor fabric?

I have aspirations and a clear path from floor worker to electrician (they deal with all this stuff too). How much does it suck unironically?
My plant uses Rockwell stuff mostly.

>>105711733 (OP)
an arduino and some relays board do the same work for 1/100 of the price, i can't understand why there is still a market for this

>>105732311
Because real time software is the devil. Arduino also makes PLCs these days.

>>105732291
i used to be a plant electrician.
I would say it depends on the company and how you handle pointless tasks.
when there are a lot of machines which are damaged but won't get fixed because of the cost you'll do the same things over and over again (e.g. 1.check if it's the same issuse as usual 2. reset 3. start.)

what type of machines will you maintain?

>>105717646
>cheap ass MCs exist
at the end of the month, the MC is not cheap after you clocked hundrets of hours to achieve the same shit as on a generic PLC with standartised fieldbus within a single day.

>>105716966
on the big ones, 4/5th of the volume is physical plugs and heatsinks

>>105717646
sometimes you need or want safety certified hardware to prevent machinery from blowing up or employees from being killed. it's smarter to rely on a 'safety plc' which undergoes rigorous testing than whatever bullshit you cobble together with stm32s. yes, the plc is probably an stm32 on the inside but you're paying for it to be designed, tested, certified by someone else.

software needs to be modifiable by end users: process engineers/technicians. you don't want them fucking with C/C++ code. PLCs use ladder logic which is much simpler. do you want to be responsible for writing a ladder logic interface to your non-safety verified homebrew PLC?
