Experimental Physics and Industrial Control System
If you’re writing a LabVIEW client application CALab sounds like the way to go.
If the goal is to serve data via EPICS, then you should consider running an EPICS IOC on the machine running LabVIEW.
lvPortDriver ( https://github.com/sbaily/lvPortDriver ) will let you do this on any OS that can run EPICS and LabVIEW.
Your LabVIEW program starts the EPICS IOC, and lvPortDriver (an asynPortDriver class with LabVIEW wrappers) handles the communication between the IOC and LabVIEW.

My 2cts - your mileage may vary:
The NI implementations of CA (client and server) were indeed getting better over time, but they started at a very low level of compatibility.
Their newest versions are pretty much working (at least for scalars), but - especially for their CA server - you are always in for some surprises, and your clients might need special configuration when talking to an NI Channel Access server.
I can just underline what Gabriel wrote: In my experience (which is obviously biased as I was working at BESSY for a long time), CALab is the most reliable, robust and stable CA client for LabVIEW.
(Doesn't just look better - it works better, too!)
Cheers,

I had the same problem with older versions of Labview. As soon I know
the waveform implementation on Labview is wrong, so you shouldn't trust
on it.
An alternative is CALab
(https://www.helmholtz-berlin.de/zentrum/locations/it/software/exsteuer/calab/index_en.html),
I've tried once and it looks much better than NI solution.
