Hello. Thank you very much for your videos. Its very easy to understand. I have a question. When you add your PLC hardware you said it to be 1BG40. Does 40 have a significance? I was told 40 is version 4.0. and you have to select it before you ADD your PLC.
Very helpful for starter, like me. One thing I am very curious how the TIA basic or pro license work. Im on trial license, what will happen if the 21day trial ends?
