What version of the IO-CU configuration utility is required for the iO1000, and can I upload programming via the SA-ETH Ethernet card?

I couldn't find a specific version number for the iO-CU utility in the manuals, which only specify using "compatible iO-CU software" (Page 2) [1].

Yes, you can upload and download panel configuration, history, and current status via the SA-ETH Ethernet card (Page 1) [4].
