So sorry to reply this after along awaited time. I encounter a hard phase of my bachelor thesis with my kinetics equation. 

Okay, I have figured it out about the issue. I use RS232 adapter for DP/MPI Network and then connect it with  USB to Serial Converter. It's quite helping though. But it can not being used to download the program to PLC. You need to use the original cable for downloading the program. I hope its helping. And so sorry for the late reply.
