If you want to connect inverter to PC it's easy. Micromasters have RS485 interface as I remember correctly there are two blue connectors 29(Data+) and 30(Data-), just attach your adapter to these connectors and use DriveMonitor.

Yes, you have to configure USS protocol parameters, use parameter range: P2009 – r2037

hi kriztof,

the parameter already set, but still no luck. I use Starter and set the PG/PC interface as PC Adapter(PPI) is this correct?

The cable schema

PC Adapter --------- MM440
DB9 ----------------- Terminal No.
7 ---------------- 9 ---- +24VDC
2 ---------------- 28 ---- 0V
8 ---------------- 29 ---- Data A
3 ---------------- 30 ---- Data B

When I try to connect the MPI & USB light are blinking but no device found. :(

I thought it's only for S7 200 connection? Do you mean Simatic PC Adapter for S7? Sorry I didn't understand you correctly.
I use RS232-RS485 converter and DriveMonitor, it works with Micromaster, Simovert, Simoreg.

Hi guy,
I did test successfully by connecting STARTER (PC) to Micromaster MM440 via terminal 29, 30 (RS485 port) using USB-RS232-PPI/RS485 cable, but the wiring should be follow:

PC Adapter --------- MM440
DB9 ----------------- Terminal No.
7 ---------------- 9 ---- +24VDC
2 ---------------- 28 ---- 0V
3 ---------------- 29 ---- TRX+
8 ---------------- 30 ---- TRX-
