I am looking for advice for how to begin to understand the very basics, I mean very basics, of PLC programming. I don't know where to start and would like some ideas. I travel every week and always have evening time in my hotel so if the start is learning via videos, great, just tell me what course online to take. I see that there are programming kits that are supposedly designed for newbies that include a small PLC, accessories, and videos, maybe thats where I start.
My main reason is curiosity, but, I have real reasons with my paying job to better understand. I design packaging equipment and I normally explain my ideas with drawings and features and let the experts do their thing....welders, electricians, programmers, etc. I have a really simple (in my mind simple) add on I would like to add to a piece of packaging equipment that would require air cylinders, photo eyes, and a vacuum. This idea would add so much functionality to my latest machine and would ultimately add a larger group of clients, that I want to build a prototype. (I know, I could use my old method and explain it, pay money, and have it built, but, I want to create it with my own hands)
If any of this makes sense and you have some guidance for me, I would really appreciate any responses. Thanks in advance.
