We are using it. It is functional but it is not a full feature CA server. We are treating it like remote I/O with CA as the field bus. We have other records on an actual IOC that take the cRIO PVs as inputs. Scaling, alarms, etc are all handled by the actual IOC and clients (display manager, alarms, archive) generally interact with the IOC PVs rather than the ones served by the cRIO. One peculiarity we have seen with the cRIO is that the first client that connects does not always get a valid response.

HIHI and HHSV: yes
ADEL and MDEL: no
