Hello HBCM;

The B&R X20 bus controller system is described as a Powerlink bus system, not Profinet.

https://www.br-automation.com/en-ca/products/io-systems/x20-system/bus-controllers/x20bc0083/

This would explain the lack of gsd files for these units. Powerlink seems to be a dedicated communication bus for B&R controllers.

The only way you could use them with a Profinet IO Controller would be through a gateway, and I have not found many such devices on the web except for this vendor:

Hope this helps,
