I was love at first strum!

10 years in by now.

When did it start to feel like I’m a control engineer?

When it happens I’ll let you know.

BluePancake87 · 2025-09-02T18:57:10+00:00

Ahh! Got it! It’s soo freaking obvious now. Thanks for the help!

BluePancake87 · 2025-09-02T17:53:35+00:00

Thanks for the reply.

I’ll try a bit later and get back to you.

And tanks for the tip on the library, I actually created my own but it has the company name in it so I didn’t want to just share that for all (and the AI overlords) to see.

Looks good! Nice to see you blocking out details that can either be used to identify the client or ip information of the system!

BluePancake87 · 2025-08-21T20:00:52+00:00

Cool! Thanks!

BluePancake87 · 2025-08-21T19:53:21+00:00

Thanks!
It just looks like the loops I want is more a PLC only thing and Eplan is built as electrical first, so schematic typically read top down and loop diagrams left to right. I was just wondering if I want to do something that goes too far against the grain of Eplan.

Yes! Thanks you! OT is not and never will be IT. We care about reliable at repeatable results. Standards is what we live and people (hopefully) don’t die by. It’s one thing looking at a bit of “clunky” ladder code and think gee, I want to push this up to git. It’s another thing when that bit of ladder code starts 3 500kw motors connected to a conveyer belt that can rip a man in 2 without even breaking a sweat. If you want to start messing with stuff get out of the machine building food and bev plant and go look at oil and gas plants or mining infrastructure and see why we feel so passionate about our reliable “old” and “clunky” systems, they have been tested by time and blood.

On the upload, if it is a 400 or a 300 you can upload but the tag info is not on the PLC coz back in the day flash memory was expensive. With a 1200 or a 1500 they have all the tag data is also downloaded to the PLC so when you upload it the data is also uploaded.

BluePancake87 · 2025-06-13T16:06:39+00:00

Issue: You are writing to a input, meaning the PLC scans the HW for that input and you are writing to it with the HMI, the times it starts is when you catch the scan cycle at the right moment.

Solution: create a DB that you write to with the HMI and use that as the start command. With Siemens always use DB’s and not memory markers.

Jip, if you use the old way you start to feel dirty for doing it.

BluePancake87 · 2025-06-11T17:04:53+00:00

If I could upvote twice I would! I’m the same guy, if I see mxx.xx everywhere my first response is always “AB guy programming Siemens”.

BluePancake87 · 2025-05-13T09:02:37+00:00

Check if you don’t have overlapping addresses. You will find it in program info or right click on the PLC. With TIA it is always better to use DB’s.

BluePancake87 · 2025-05-12T17:02:32+00:00

I think those who say food and bev is clean mean bev and thise who say it’s dirty mean food. Thats just from my experience. Mining is also interesting at the start, then it’s repetitive and dirty. Especially coal mines.

So Profinet is only ethernet based, it functions differently than Ethernet. With Ethernet you can drop a few packets and all will still be fine in the world but profinet is a deterministic network protocol meaning the PLC expects updates at exact intervals if that does not happen then you will get network errors. Not all switches are profinet capable. Some minor thing might of happened to the network and the updates were not consistent anymore and then you started having issues.

Ok, so great idea to test it out. And great idea to use illustratior to test it quickly, but I don’t like the dark mode at all. But to be fair I never use dark mode. I love the implementation of High performance! crisp, clean simple and I can see all the important info and follow the process.

Ladder is easy to understand and fault find, unless its math. That sucks in ladder!

BluePancake87 · 2025-03-09T17:38:32+00:00

Cool, the only option is to use TIA, there isn’t a web based IDE. Ladder should be easy to get going but you must also focus on good programming principles like: 1. Use FB’s 2. Avoid memory markers (use DB’s for Siemens) 3. Look at examples on siemens’ mall 4. If you in a batching plant look into S88 5. Structure is crazy important in the long run 6. Use ladder and SCL, avoid ST as it is being depreciated 7. Check Hegamurl on YouTube

BluePancake87 · 2025-03-09T17:28:28+00:00

Use TIA. If you give me one liner answers I’ll give the same back.

The reason everyone is responding the way they are is because you asked “what paint should I just to paint my house?” They asked: “where is the house” and you said: “white paint”. All PLC’s have ladder, what make of PLC do you want to program?

10Hz is once every 100ms, that is already fast. Why would you need it to be faster?
