The last screenshot tells that the ESI files for the drives are missed. Do you know the fw version of the drives? Or do you have updated the drives?
I assume the bus coupler is not switching to OP or make the process data valid, because of the drive config issue. You can test it, when you temporally remove the drives from the configuration and the setup and use the IO alone.
Please check the revision of the drives, the EtherCAT scan dialog can show the revision, when you use the context menu of the device type header cell in the scan dialog to display it.
Organize the old ESI or update the ESI and drives to latest version.
