2) I have this situation, because this message?

So, you should select micromaster slave and then to add modules depending settings into drive.

Select PP03 if you do not want to read or write inverter parameters; select PP01 if you do want to read/write parameters. If you want to read back data such as motor current from the inverter, it is worth considering one of the options with PZD words 3 and 4, as you can then do this without reading inverter parameters.

Look at How do I read / write parameters using PROFIBUS on the MICROMASTER 4?

About first issue look at http://support.automation.siemens.com/WW/view/en/30558965 or could explaine a little bit more?
