You have a good presentation on NI website: http://download.ni.com/pub/branches/uk/handson_followup/epics_ral.pdf
There is no alarm on RT target. Some EPICS alarm fields are there, and you can change them with a caput, but it is not enough to make it work.

In addition, I have a LV EPICS solution that is working pretty well on cRIO-9074 (VxWorks) and not starting well on cRIO-9039 (Linux).

Best,
Paul

Objet : RE: EPICS for CompactRio

As another testimony.... I confirm that the best way, in this case, is using an intermediate real IOC, to read from NI shared variables, and have the full EPICS features in the real IOC.... about the first initialization fails, I have had similar behavior.

Diego

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
