Hi everyone,

My Problem is that i receive just FFFF in all registers that i request. I set the correct MB_Unit_ID in the DB.

Do you have any suggestions?

I sent you also the Documentation of the registers. (my inverter is the sunny tripower 6.0 SE)

The MB_Client_FB is in a OB30 with a 2s Interval (Works fine with my Siemens PAC2200).
 

The Connection is established without any Errors.

Thank you in advance of your efforts!
Thomas
