Fancy a bit of PLC? No?

Never mind, here we go!

The control, by the way, has been installed and is running in the meantime. However, there are a few changes: All cables were routed to the meter cabinet, and the control was mounted there on free DIN rails. I also replaced the terminals with three-level terminals due to space constraints.

Of course, I didn’t take a photo again.

But I can show the programming in #FBD (Function Block Diagram).

I have many LOGO versions but no 0BA4. 🤔

Anyway, I have now taken an OBA3 24V AC/DC and plugged the old control unit into it. As the controller works with 24V like the 230V version, this is not a problem.

It also starts and that means the controller works. Wonderful! In the next step I can read out the program 🙂

Today I found the time to finish the #wiring 🫠.

I used some smaller #contactors that I found in my stash. I then simply applied voltage to it as a test. The first contactor also switched directly every second because a program was still active on the #controller.

Now I just need to program the controller, which won't be a big deal.

Now something completely different. lol

Now I'll show you the PLC-CPU. The Siemens Simatic S7-1500.

I like the control panel that has exactly the same buttons as the cute tiny Siemens Logo!

So that it doesn't get boring... on to the next control cabinet:

Siemens Simatic S7 ET 200S with a few more modules.

There's a bit more to it than just a few conveyor belts, labeling and packaging machines.

But also decentralized again. The PLC-CPU still has to control servo controllers and frequency converters via ProfiNet.

I have photographed a few
decentralized PLC peripheral modules that I come across at work. The PLC CPU sits separately and is connected to this modul via ProfiNet.

Let's start with the small ones first. lol

I sorted my LOGO's and tried out how high I could stack them

It's getting a bit Lego-heavy here, but I can't find anything else at the moment.

At least I've #integrated one of my #toys. 😁

I used a #SiemensLOGO 0BA5 with #extension to #automate a #Lego #LevelCrossing (4532). It #controls the station #lighting, the #TrafficLights and the level crossing #barrier.

The #controller runs on 24 #volts, the lighting and the #motor are #regulated down to 3 volts via a #StepDown #module.

Oops, bought another one. At a good price, I can't say no. A programming cable is also included.

It's about time I installed one again.

I don't even know how many I have now.

I would definitely recommend replacing the entire device for safety reasons.

Maybe you still have a warranty?

PLC = #ProgrammableLogicController
(I like to use)

I don't think it's worth using a #ProgrammableLogicController for an #AdventWreath.

Or is it?

Only here, from the back.. I didn't show that on Twitter.

It works with a standard USB powerbank that produces the required 24V control voltage with the help of a step-up module. Everything is controlled with a Siemens Logo with transistor outputs.

The Safest Model Roller Coaster

[Jared Holladay] is a computer engineering student at the University of Cincinnati and a life-long roller coaster fanatic. A lot of people look at roller coasters as an exciting example of physics, like potential energy versus kinetic energy or inertia, and rightly so. [Jared] looks at them and wonders about the controls. Video also below and there is a feature-length explanation with more details. Some Hackaday readers and writers can identify the components, so we think his coaster model belongs here.

Like many folks in this field, he's built K'nex models to get a handle on construction. He's toured STEM shows with the tracks and undoubtedly wowed kids, adults, and physics teachers, but since he can speak to the programming, he is a triple threat. Now, he's growing out of the toy construction plastic and moving into 3D printed parts with needle-fine tolerances.

His latest base is extruded aluminum, like what you'd want in a rigid CNC or printer. In addition to the industrial-grade surface, Rockwell Automation sent him a safety programmable logic controller, PLC, and a touchscreen HMI. Our fellows in the industry tell us those are far beyond the price scope of regular hobbyists. But fear not; your Arduino clones will suffice until you get your first grant.

The point of all the ruggedized hardware, aside from authenticity, is to implement safety features the same way you would in the industry. The redundant PLC connects to inductive prox sensors to check train speed and location. Other moving parts, like friction brakes, have sensors to report if there is a jam. After all, it's no good if you can't stop a train full of people. There are hundreds of things that can go wrong. Just ask [Jared] because he programmed on-screen indicators for all of them and classified them to let an operator know if they can keep the ride moving or if they need to call maintenance.

Not all homemade coasters are scale models, and some of the traditional ones have more than meets the eye.

Thank you, [Milo Bascombe] for the tip.
