Jalal,I was able to r/w using U32 data to a waveform record.I'd have to dig a little to resurrect the details, perhaps later.-psOn Tue, May 26, 2020 at 3:36 PM Mostafa, Jalal (IPE) <jalal.mostafa at kit.edu> wrote:Writing double scalar values to a ai record works great.
I tried both aai and waveform to write array values of doubles but no success.
I am using LabView 2018 SP1. Do you have a list of what's working and what's not?
Best,
Jalal

Subject: Re: SoftIOC and LabviewJalal,Can your labview write scalar values (e.g. to a longin record ) to your softioc?Have you tried writing your labview array to a waveform record on the softioc?
Using earlier versions of the NI EPICS software, I seem to recall there were some data types that wouldn't work (I think double was OK). I haven't tried the 2020 version but glad to see it has been updated.

Hi All!
I am trying to write an array of doubles from a LabView EPICS Client using EPICS Client I/O Server to a softIoc instance with the corresponding record:
record(aai, "dummy:array"){field(DTYP,"Soft Channel")field(NELM, "10")field(FTVL, "DOUBLE")}I can see the LabVIEW being connected to this record but no written values to softIoc instance. The issue is only happening on LabView but not when using other clients like caput for instance.
What is the correct way to write array values from LabView to softIoc records?
Best,
Jalal
