Hi, I'm looking for a module for my Siemens Logo that can compare multiple digital signals. For example, I have five inputs, and it should compare whether all of them are providing a signal and whether one is not. It should then interpret this as interference and provide a digital output signal. If such a module exists, what would it be called?

Loading...Hello everyone Can someone please explain to me, using a concrete and simple use case, why we need "interfaces" in C#? As I understand it, an interface is a "contract." So, I'm clearly defining a MUST. For example: class HumanoidsAI:IMensch Here, I'll simply tell "THE DEVELOPER" that the Humanoid AI class absolutely must implement ALL…
Hi, my Samsung Galaxy had 0% today and had to be charged with my charger. After connecting it to the charger, the phone vibrates and displays a blue droplet on the screen. However, there was no water damage, and I even dried the phone (USB port) several times with a hairdryer. Nothing seems to help,…
I'd like to know how a computer works, as I'd like to start learning how the devices I use in everyday life work technically. Can anyone recommend a tutorial that clearly explains, for example, what a CPU is and what it does?
Hello, I deleted my Google account yesterday so that my YouTube account Today I restored my Google account. When I manage my Google accounts, my YouTube account is also listed there. However, I can no longer log in to YouTube. Does anyone know a solution? Regards
Good day ladies and gentlemen. I've been working with self-hosted LLMs for almost half a year now, and yesterday I wanted to try something new. I got StableBeluga-7B because it's smaller and therefore generates answers quickly. These answers aren't as precise as those from StableBeluga-13B or StableBeluga2, but in my experiment, speed is the primary…
I've equipped two of my USB sticks with autorun and batch files so they can open files or browse the internet. Does anyone else have any suggestions?
That’s what you do with a logic analyzer. There are models that are easily connected to a PC/laptop via USB. The included software then shows the result as a signal-time curve. For example, this: https://www.kaufland.de/product/470247066/?utm_source=shopping&utm_medium=non-paid&utm_campaign=pricecomparison&sid=50052146
It can measure 16 digital signals at the same time and thus represent them. You can also record it.
I believe this is about the implementation in a Siemens logo.
Hello,
yes, that makes every AND/NOR component!
So simplest electronics!!
