The user is not able to see the PLC or SLC. One suggestion Is to try different drivers or try a different virtual machine or use a computer with windows xp sp3 but without a virtual machine. Update** The VM has to be set to NAT, so the adapter appears properly in Linx on both the Win7 and WinXP VMs. That the Windows 10 OS has to be refreshed unplugging and plugging again the unit so any conflict with the drivers or the Windows registry can be updated and eliminated.  Rslinx 2.54v had a bug reported in a Rockwell documentation, so please try with a newer version of Rslinx.
