Hello,

I am having some trouble setting up my new PG. I have a PG M6 with the latest Siemens software on it. I am trying to add some of the older software using ORACLE VM. I have Windows XP with ComProfibus 5 and Windows 95 with ComProfibus 3 on it.  Both virtual machines have SS52 loader on them.  I know that I can't use Windows 95 since it doesn't understand what the USB is. But is there any way that I can use the emulated computer to connect and see the Simadyn D rack? I know that I have everything setup right since I can tell that it sees the USB to Serial and the rack but it can't communicate to it.  

Hello EHuggs,

you have written that you have the latest Siemens software. This is TIA Portal V17. But TIA Portal V17 is not compatible with Windows XP. You need Windows 10.

Regarding to the settings for the VMs see the information of the FAQ:
