Commented Unassigned: Plant time / software version error [177]

Hello,

My inverter is a SMA SB 4000-TL20 (running since 2009 in Germany).
I am working with SBFspot 3.3.2.

Since a few month is discovered, I always get error when reading inverter data....

Rest works.

Login in via SMA Sunny Explorer Windows-Software, Time can be read/changed... Software version is displayed..... ?1?

If this was always the case I can't say; I looked closer onto log-data when discvovering "123solar".
From old "SMASpot" I don't have any log-files remaining.

Any ideas?
