Haven't posted about this topic in a while.
Kinda always looks the same anyway. 🫠

An open electrical control cabinet with multiple rows of components. At the top are miniature circuit breakers (MCBs) and residual-current devices (RCDs). Below them are terminal blocks with organized blue and orange control wiring. On the left side is a Siemens SIMATIC S7 PLC with several I/O modules. On the right side are Siemens industrial Ethernet switches. A Siemens Sitop power supply is also installed. Green Ethernet and fieldbus cables are connected to the switches, while various control and power cables exit the cabinet at the bottom through conduits. Several yellow warning labels are attached to indicate electrical hazards.

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 (Function Block Diagram).

The diagram includes yellow blocks representing timers, relays, and triggers, connected to show the logical flow. Features like motion sensors, outdoor lighting, and fountain activation are configured with specific time settings and conditions.

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 🫠.

I used some smaller 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 .

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

An open damp-proof distribution box with various electrical components and wiring. In the top row, two ABB contactors are on the left, followed by a 2-pole RCD and a controller for a light sensor. On the right is a Siemens LOGO! controller with a green-lit display showing 'Su 00:00 2008-01-01'. The bottom row contains Weidmüller terminal blocks in grey, blue, and green-yellow, connected by black, blue and brown wires.

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 one of my . 😁

I used a 0BA5 with to a (4532). It the station , the and the level crossing .

The runs on 24 , the lighting and the are down to 3 volts via a .

Lego train set 4559 and Lego level crossing 4532 with lego 4 volt motor for the railroad crossing and working traffic lights. Also shown is the Siemens Logo 0BA5 with extension for controlling the level crossing with many wildly laid wires. The control panel for the Lego train can also be seen in rows.

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?

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.
