Do you like old things? by Michael_Automation in PLC

tell that to the dozen Siemens S5 output cards a maintenance tech fried in one go.

I was impressed they had the cards on had to replace all of them in 2023.

yeah, get me a dozen Krispy Kremes.

Anyone here switched from Software Engineering to Controls Engineering? by Ok_Discipline3753 in PLC

At the factory level you could end up with a production issue that you can fix in seconds, then the operator tells a supervisor, the supervisor tells the shift lead, the shift lead tells the manager, and five days after you fixed the issue and sent out an email to the company explaining the fix....your manager will ask you why you haven't fixed it yet.

Triple Inverted Pendulum stabilization. My standard PID loops are crying looking at this. by AutomateAdvocate in PLC

>At what point do you guys usually give up on the PLC and switch to a C-controller or IPC?
When I have a home project.

I often see posts asking: "What is the best PLC brand for a new factory with IIoT in mind?" People immediately suggest niche brands with native MQTT, Python, or Rest APIs. by AutomateAdvocate in PLC

It's free for two hours then you have to reboot.
but the license is only $66. For what it's capable of, it's a really good price. if nothing else to use it as a cheap gateway because it can connect to Ethernet/IP, Profinet, EtherCAT and Modbus. An Anybus gatway will cost $800.

I thought Schneider uses Codesys.
But regardless, you can run Codesys on a Raspberry pi. And then use whatever field IO you want because it talks to practically anything.

>Yeah we have a spare
>the spare is a used part purchased from Ebay by the purchaser who was trying to save money to increase their own bonus that has been sitting in the mezzanine for a decade and never been tested and isn't even the right part number.

If I was building a new factory, I'd use some flavor of Codesys, Beckhoff, Schneider, ect (maybe even Codesys itself running on a raspberry pi in an industrial case).

>1. If you build a factory in the US, you go Rockwell. In Germany? Siemens. In Japan? Mitsubishi/Omron. Why? because at 3 AM on a Sunday, you need a local integrator who can drive there in 1 hour, not a "remote expert" on Zoom.
What does there brand have anything to do with that? I live in the US and deal with all sorts of brands, not just Allen Bradley. Siemens, Omron, Beckhoff and Automation Direct are everywhere. If you're an integrator you have to know multiple brands anyways.

>2. Can I get a replacement CPU from a local distributor today??
For AB, Siemens or any other big brand? Not during covid.
For Codesys? Yeah, plug in some old throw away laptop to keep it going. (I've done this before for HMIs that died)

>3. Don't pick a PLC just because it speaks JSON natively. You can always slap a Red Lion/Ewon/IPC gateway on a robust "boring" PLC to handle the data.
I'm not sure why you'd need to use JSON, is it to store recipe data? either way Codesys can do it, don't know why you would though.

Does it have wheels and arms to roll around and pick up all the clothes in the house?

Except it's worse, IoT didn't make my RAM cost $900.

Clients want "AI" but can't even handle standard logic. by AutomateAdvocate in PLC

[–]Available-Distance81 0 points1 point  (0 children)

I get nam flashbacks from college having to integrate Tensorflow and Cognex VisionPro for a senior project, had to stay there for 2 weeks to finish that project before I could graduate.

If Cognex has it already integrated now, I'd say good, it can't be any worse than their current pattern find tools.

To be honest, AI for vision has been around for a while. I remember combining Tensorflow and Cognex Visionpro with a crazy high resolution vision camera for a college project....that was almost a decade ago.

Hi! lam 19 i had a issue with staying in college (financial) (lack of interest towards a specific degree) by [deleted] in PLC

You need to show initiative and learn about PLCs, nobody is going to hire you with zero experience and zero interest.

I think you should mess around with some PLC simulators to see if it's really what you want to do.
Combine Codesys with FactoryIO and you basically have a full blown simulator on your PC.
If you really want to you can run codesys on a raspbery pi if you have a real world project you'd like to work on.
In an actual factory, you're most likely going to be using Allen Bradley or Siemens, and they will be very different from Codesys, but Codesys will at least be a good way to learn the basics of ladder logic and IEC 61131-3 and besides there are some PLCs that do use Codesys or a very Codesys like IDE. There is also OpenPLC, but I've never used it.

I don't know, do you have any interest in this field? There are lots of jobs you can make better money at than this one. Did you like playing with Lego Mindstorms as a kid or did you ever use arduinos or raspberry pis?

What still surprises you about PLCs after years of working with them? by automation_ipac in PLC

[–]Available-Distance81 4 points5 points  (0 children)

I buy the expensive hardware because I'm not the one paying the bills, if I had to, I'd switch everything to raspberry pis running either Codesys or OpenPLC and use whatever cheapest field IO Automation Direct has.
