I want to download the program from the on-site PLC to my computer, without affecting operations at the site. How can I do this? Those who have done this before, please provide specific steps! Thank you

Connect it to the MPI port via a programming cable and then upload it; this operation does not affect the field setup.

I did the same thing, but I couldn’t establish a connection. Do I need to make settings in the software’s PLC?
