Subject: Use default value if CA link error

Dear all,

I have a string input record which value is retrieved via CA link. When remote
PV is not available (e.g. missing IOC) I would like to set "EMPTY" as string
input value.

My idea is to use scalcout record from synApps with CA link connected to INAA
and IAAV connected to INPA, defining the output by checking INPA value and
selecting INAA (Ext PV OK) or "EMPTY" constant (Ext PN NC).

Before adding scalcout record to my IOC I would like to know if this is a good
approach. Is there a simpler solution?

Thanks,

Luca
