Fellow PLC Lovers :nodi:,
Good day!
I'm back again for another question. This time for Modicon M340.
I am currently developing a user program for a Soda company using the said PLC system above.
The requirement I must meet is that whenever a power outage occurs, the process shall return to the step where it was interrupted after power restoration. I am currently looking at M340's System Bits %S1 (Warm Restart) , %S12 (PLC Running) , %S13 (First Cycle After Switching to Run) and %S21 (First Cycle Task) but still confused on how to implement them to meet such requirement.
Can anyone help me with this one? Thank you very much.
