With regards to the IO mapping, I have integrated many Keyence IVs over the years (IV 1, 2 and 3 models) and their Ethernet/IP and Profinet IO mapping is very well documented in their manuals. In addition, on their website they have the EDS/GSD files as well as Tag description files in CSV format. The tag description files are generally for the AB 5000 series processors, but I think would work for the Micro series as well.
As I said this is for IVs, but I would hope they provide the same for the VS series. I will be trying a VS out soon in the near future so I will find out
