Siemens cabling: CP5711 to MP377, 9-pin, D-sub

Should be an easy question. I just can't seem to search the right words...

I just got a Siemens CP5711... one goes to the PC via USB cable. The other end has a 9 pin D-sub connector, and this will connect to a MP377 touch panel. I can't find anywhere that spells out exactly which cable accomplishes this. I found the pin-outs in the CP5711 manual, but I'd prefer not to make my own cable. Can someone tell me where to find this cable already made?

I know there's a third-party cable source that is mentioned on this forum. It's still not clear to me witch cable is correct.

Here's a table with preassembled ones

I would assume that you need to buy standard Profibus cable. It's an RS485 network with shield/ground.
