Communication PC with S120 drive

[krome]

I have Step 7 professional and Starter install in my laptop I have tried to communicate with an S120 drive. I just want to use the Starter program I have a profibus cable that came with the training unit. I have try configuring the PG/PC using profibus with no success. Do I need a special card to install in my laptop or do I used the serial port? I took the drive training class 2 years ago trying to refresh my memory on how to commission an S120 drive.
Thanks
Rick

What profibus adapter are you using?

what do you mean by profibus adapter? The profibus cable is connected using a gender changer 9 pin connected to my serial port in my laptop going to the CU320 profibus 9 pin connection. Is there nother way to communicated with the s120 drive?

That will never work. For profibus you need a profibus adapter
What is the profibus master in your system?
You can program the drive with serial. Look under the cu. See the other 9 pin. Use a serial cable and plug in to it.
Set your pg pc adapter in Starter to serial 38400.

this is a training unit i did this 2 years ago im trying to refresh my memory i did not do a good job on taking notes. the profibus adapter is that the siemens cable use to program the plc as well?? The CU should then have another serial connection then?

.... trying to refresh my memory on how to commission an S120 drive.

Are you using a CU320 stand alone with stop/start via the CU terminals ?
