I Want Upload Or Download From A Cnc Machine.
I Hv A Pg ( Field Pg With S7 Plc Softwares Like Simatic Manager).
Which Additional Software & Cable ,i Need To Load Into Pg To Do This.

I've you've got a PG, it should have an MPI/DP port. Just get a regular Profibus cable, connect one end to the MPI/DP port on the PG, and the other end to X122 on the NCU.

Open up the Set PG/PC Interface and set the interface for MPI, 187.5kbps. If you open the Accessible Nodes, the PLC should show up as address 13 or 2, depending on how yours is configured. THere may be a couple more addresses to (6,1,...). Just open blocks folders until you find the one thats got the PLC blocks into it. Once you've got the address sorted out, you can upload and download.
