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).

A screenshot of an FBD (Function Block Diagram) in Siemens LOGO! Soft Comfort software for controlling garden lighting and fountains. 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 🙂

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

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.

I love these little programmable logic controllers 😍
