Hi all,
Since Mac OS Big Sur we experience some issues with connecting to new Siemens PLC devices over ethernet.
Siemens uses an ISO protocol once a netwerk device has no internet connection, but for some reason this is blocked somewhere between Mac OS and Parallels.
When I connect my USB network adapter directly to Parallels there seems no issue.
When it is connected through my Mac and share network adapter there are no devices found.
There is no problem once we have the same setup with Mac OS Catalina.
Currently using Parallels 17, but we also had these issues on Parallels 16.
Can anyone help me?
Thank you,
Pjotr
