Steve I am using a Tripp-Lite CPXX URT Chip with good results windows 7 and 10. I would stay away from the Prolific Chip ones as to the Chinese clones circulating with driver issues. . A Good CPXX URT Chip or FTDI should work without issues..
If you can take a photo of your configuration again maybe the front of the GBI001 all should be green, and you can also look at the Fault Table on the RX3i as it will have some useful information if there is a fault in the I/O. Make sure you selected the correct Chassis under the Modules in your configuration and make sure the PLC is in Run. Don't forget to power cycle after downloading configuration to the module. Not sure what kind of Communication cable you are using but doesn't look like standard serial wire used for genius.. I never used anything but the recommended so don't know how others perform.
