    The cable tray and DIN rails are riveted in place, and I've started with the wiring 🫠

    From this point on, I had to plan and draw the control circuit. Of course, it will be properly done in the end. But for now, the sketch will have to do.

    Basically, it's like PLC programming with ladder logic, just with real wiring.

    I have a new project. I would classify it under #PLC, even though it is #hardwired.

    It's about an exhaust control system for two workbenches in an explosion-protected area.

    Basically, it's a series of safety chains to ensure that the machines only run when the exhaust fan is operating. Both workbenches will be monitored by an airflow sensor, which must be routed through a zener barrier.

    I will try to show some of this tomorrow.

    Here is an automated CNC milling machine (photo from the back). As this machine fetches the material itself, it is set once and then continues to run on its own in the dark. It's just stupid when the program is finished or there is an error and nobody notices. So what to do? We put a stack light on it and connect it to the controller.

    Today troubleshooting a Siemens Logo 0BA4 230V.

    The customer already has a new one installed. (V8.3) Nevertheless, I am interested in whether I have programmed the new one correctly. Because there was no documentation.

    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 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
