I am starting to understand now. You don't have the program, and you cannot go online with the PLC that has the program to upload the program from the PLC.
Is that correct?
This program is ... interesting. It seems to be the controller for some kind of swing adsorption unit.
You need to determine what the state of every one of the 16 bits of B3:1 should be at each step, and put those bits' values into N7:0 for step 0, N7:1 for step 1, etc.
Unfortunately, that also includes bits B3:1/8 through B3:1/15, because if this was a working program, then the SQO instruction also writes to those bits whenever its input rung is true, which suggests that the values of bits N7:0/10, N7:1/10, ..., N7:7/10 should probably (but not necessarily) all be 0, and it is possible that all other bits /8 through /15 of N7:0 thorugh N7:7 should also all be 0.
