We're a used machinery merchant and have a Siemens PLC that has lost its program due to a dead battery. We have the software to download but, at the moment, we're unable to get a connection.
My boss tells me it's actually a servo drive with PLC built in. It's a Sinumerik 840D 6FC5247-0AA00-0AA2.
I'm using a 6ES7 972-0CB20-0XA0 USB to 9-pin DSub cable and Simatic Manager V5.5. I open Simatic Manager then open the project from disk. I go to Options/Set PG/PC interface and there are several options for drivers. I've tried PC Adapter.Auto.1, PC Adapter.MPI.1, PC Adapter.PPI.1 and PC Adapter.PROFIBUS.1. The Profibus driver has <Active> beside it - I'm not sure of the significance of this.
When I use the Auto driver and try to auto-detect the network settings, it says it's set to 187.5 kbits/s but that I have to set the parameters manually (or words to that effect).
Everything I've tried (all three possible ports on the front, each of the drivers mentioned above with the local address set to between 0 and 6) doesn't work - I get nothing appearing in the Accessible Nodes window.
When I click on the Blocks folder in the navigation tree and Edit/Select All then click the Download button, after a wait it reports that the local station address is higher than the highest address on the network.
I've attached some photos that may shed some more light. Any help would be very gratefully received.
