Have you checked your CPU online? Is the SFB existing? Than it can be used. If not, ... no chance. Good luck Sabine

I tried your idea using PLCSim (CPU 315-2 PN/DP) and the SFB37 appears in online mode, but I don´t know if this issue can be answered using PLCSim instead "real" CPU ... That´s my doubt ! Regards.

You can use BSEND toemulate an AR_SENDand fool WinCC by adding the required (AR_SEND)header to BSEND packet ..." Please take a look at this thread Data logging in CPUis very interesting and useful. Regards.
