We've been using CALab for a few years now, with few problems. Carsten has been regularly updating it. We use LabVIEW with CALab as our primary user interface on  three beamlines at the APS, mostly performing spectroscopy and microprobe experiments.  CALab is quite easy to use, and I've worked with several user groups to use it for integrating their LabVIEW-based data acquisition applications on our beamlines as well as others. I don't know much about raw performance, as we don't really use it for real-time or high throughput situations, but it works quite well in my experience.

Hello

Here is a nice summary:
ftp://ftp.ni.com/pub/branches/uk/handson_followup/epics_ral.pdf

We have tried EPICS module in LV 2013 and our-own-way: use of LV AMC module and EPICS streamdevice , both with focus on LV Realtime targets ( PC compatible one).
- The first was fine for small sets of variables.
- The second just sends structured data with UDP and requires little bit of development on both sides. It is promissing, however AMC will include desired TCP support someday soon.

As far as I know about the others:
- CA lab doesn't work with LV RT targets,
- SNS and ObservatorySciences are not publicly available.

We haven't found the right one yet, I'm afraid.

How frequently you intend to R/W you data to LV ?

Cheers,
Tomas

Hello, 

I am wondering if someone knows how to interface Labview (Windows system) with the EPICS. I am going to use Labview to control a equipment during my beamtime. It would be convenient if EPICS can write and read numbers from Labview (e.g. scan). 

Thanks, 

Yuan Gao
