Hi, sorry, never had any experience with this thing. I myself recently began to be interested in this topic, maybe someone here knows it better? I could use some advice, too. I want to make my own workshop and I need cheap electric parts, even old ones, but the main thing is that they work. My friend recommended one site to me, where I can get a PLC. Well, I think there are still some options, right? If anyone knows the best site where you can buy electric parts, I would love to learn about it, and the faster the better. Thank you, good luck to all!
