Hello... I have eliwell ID985 / ID to communicate through MDOBUS which only supports write function 16 (Preset multiple registers) ... I'm trying to write with wincc but wincc writes the data as function 6 (Preset Single Register) ... Does anyone know if I can write through function 16 with wincc ??? PLEASE SEE ATTACHED IMAGES

HI 8Noodles I am using wincc 7.5sp1. In the image you can see the packet captures that I do with wireshark, it shows that wincc tries to write with function 6 and the equipment responds with a failure. then I make another screenshot with wireshark using kepware and it writes it well but using the 16 modbus function. Basically I need to know if there is any way that wincc writes through function 16 since my eliwell does not support function 6
