Hello,

is the PLC displayed if you start accessible nodes?
How you make thew connection to the PLC? Ethernet or PROFIBUS/MPI?

Which Software do you use?

Hi,

please check this:

About an interface (MPI, Profibus DP, Ethernet ) you must connect the Step-PC with the S7-CPU.

At PG at PG/PC interface you must "set accesspoint" S7online to your Interface card.

Then You have at Step7 the upload function

Hi..

Check your interface configuration, I haved the same problem with the interface (ethernet) my IP was misconfigured.

"upload station to pg"

means CPU online -> Harddisk of PG.
