Hey, I am in the process of learning how to program the S7 PLC, and I am trying to make sure that I understand how the Siemens addressing works. I am very familiar with AB's addressing, but Siemens is pretty different from that. From what I understand, each card, regardless of how many terminals, has 4 bytes of memory assigned to it. So if there are 4 cards, the 1st and 3rd are input, and the 2nd and 4th output, the addressing would be like this:
I0.0-i0.7, I1.0,
Q4.0, Q5.0
I8.0, I9.0
Q12.0, Q13.0
(All cards are 16 bit)
Please let me know if I am understanding this correctly.
Thanks!
