Subject: Accessing NTAttribute of an NTNDArray from Phoebus?

Hi EPICS users,

 

I’m using Phoebus/CS-Studio to work with a data stream of PVAccess NTNDArray. The NTNDArray normative type has an “attribute” element, which is an array of NTAttribute[]. Does anyone know if I can access these attributes from within Phoebus/CS-Studio? Thanks!

 

The closest I’ve gotten so far is to build a Probe:

 

pva://MYIOC:myarray/attribute[2]

 

Which would pull out the second attribute and show text that includes details; however, this doesn’t give direct access to the value field of the attribute itself, which I’d like to show in a Display Panel.

 

Thanks!

 

Scott
