Cu,Tm telegram?

Dear experts

I'm in the situation that trying to fix a S120 drive system while just learning about it and For me its complex as hell .

For telegram between drive and plc you can see the both of  data transferred and the logic behind that ,and it totally  make sense ,but for tm31 telegram I just could see the

one side of the data ,for example for r722, on side is cu di status and it gose to P2051 for example pzd5 and after that i lost the track ,where is the final destination of this data and how drive use those data ,it's very unclear for me .

Thanks

Thanks a lot for you fast and kind reply

Please could you take me a little further:

As you see in the image, there is separate telegram configured for TM31 and drive And for example parameter r2901 as PZD1.1 exist twice, ones in drive and ones in TM31 telegram with different value or interconnection, so if I’m right where does r2090 TM31 goes from there ,and if I’m wrong why is one parameter with 2 different value?

Thanks a lot

Best regards
