Hi,

Recently I bought PC Adapter USB MPI, product of AMSAMOTION (chinese copy of Siemens 6ES7972-0CB20-0XA0). I can't make it working not on S7-200 (Microwin), nor on S7-300 (Step 7 v5.5). Just it cannot be connected to the PLCs. I tried PC Adapter PPI, MPI, Profibus PG/PC Interface, no luck. In Device Manager the cable is visible, that's OK. The LEDs are ON too, so the adapter is power supplied obviously. Does anybody have experience with this cables?
Thank you in advance, guys!

Hi again,

The video on Youtube shows the usage of PPI cable, and my cable is MPI.
Also I tried the cable on XP, same outcome. I guess it needs AMSAMOTION driver as mohdabshr advises , but I could not find it on their site. I will keep on looking for it, just nothing left to try.

Hi,

Thank you very much, xflash, it worked using the settings for Profibus. I wonder why it did not work with the settings for PPI. Any explanation?

MPI, PPI or some other Siemens RS485 protocols except Profibus-DP are based on Profibus-DP, also your pc adapter maybe is A2 type, you are selecting wrong one.

This is a little problem :) ,for the real work, just finish your work and concentrate on your logic :D .

Good luck.
