RE: info about VI to get waveform

["Pawel Kowalski - BiRa Systems Inc." <pawel@bira.com>]

Hello Clelia,

 

I haven’t done much work with the SNS module so I’m sorry I can’t give much advice there. However, it should be worth noting that as of LabVIEW 2009 the ability to bind process variables to shared variables is built right in. If you don’t have LabView 2009 you can also download an EPICS client for LabVIEW 8.6 here:

I am not aware if it directly supports waveform data. I do know that it supports arrays as the record type and as far as I know that’s what waveform data is. Since this is also officially supported by NI they should be able to offer you help if you have issues with a particular record type, their big physics group has been and continues to be very involved in this development . If you look at the big-physics group under NI I know that Thierry and Arun have been part of that development and they might be able to answer your questions in more detail if nobody jumps in here first:

Subject: info about VI to get waveform

 

Hi everyone,
I'm Clelia Scudellaro, I work in Italy at the LNL for Mr Mauro Giacchini. My activity is to create a user interface using LabVIEW as an EPICS client. To do this I use the "sns template", that is the library that implements the basic functions of Channel Access library, sinchronize and monitor methods of PV reading/writing, for example: CAInit.vi, CASyncGetShort.vi, ecc. I have a problem: I need to acquire a waveform data and I can't find the right VI to get it, does it exist? If yes, can somebody tell me what is it its name? And where I can find it?
Thank you very much for the kindness.
Clelia
