Siemens firmwares 2.7 , 3.0

Hello.
I heard about new siemens firmwares releases that changes some diagnostic functions. The firmwares changes something in Profibus communication. Also old diagnostic FB125 is not working with new firmware. They made a new functions for diagnostic ....

So do you have some infos about changes in firmware or some links??? Thanks

Siemens support is the best place to find information about firmware versions.

Apart from that, I think that the standard block FB125 has been replaced with FB126. The new block should work with both Profibus and Profinet.
