Output the actual position r2521

I would like to output the actual position r2521[0] CO: "LR position actual".
However, this signal is not offered in the list of "further interconnections" for p4071[0] CI: "TB30 AO 0 analog output signal source".
Alternatively, the r479[0] "CO: Diagnostics encoder position actual value Gn_XIST1, Encoder 1" is not available, either.

What can I do?
