Switch from CA to PVA for interaction with EPICS PVs. PV Access gives us many benefits over channel access including structured data, normative types, better data typing, and stronger array performance. This would require importing the p4p package and using it's Context methods.
Not all EPICS IOCs at SLAC are PVA compliant. IOCs on EPICS version R3.14.12 do not support PVA, but EPICS R3.15+ does. A query-able list of EPICS versions can be gathered from this command on production:
caget -S `eget-ts ds -anamae=%EPICS_VERSION' | grep R3.14.12
