Hello

I don't know if I can help you. So in your case , I suggest you to take GSD file for each drive from his CF-Card in the directory "SIEMENS/SINAMICS/DATA/CFG. After select and configure in drive side how many data will be exchange. I guess you already connected and checked cable and connector for all slaves and master, according "Profibus connection". And also downloaded hardware configuration to all. And this is basic things, no consider Modicom PLC...
