Hello Wago,

I have reviewed your attachment.

Your document is talking only about the HMI part of the C7.

What about PLC?

As I told in my previous post, for PLC you can download and upload as if you are working with S7-300 (according to manual link (Volume 1) of my previous post.

For HMI (OP25, I have told about programming cable. I did no told that you can upload from it.

Have a nice day.
