RE: waveform record

Hi,

 

you need to use the  –a  option of caput to write to arrays, in this case you would type:

 

    caput –a twf 5 1 2 3 4 5

 

(the first “5” is the number of following array elements to write)

 

Regards,

 

Freddie

Subject: waveform record

 

hi, 

 

when I creat a testApp and a soft waveform record as following:

record(waveform, "twf")
{
    field(SCAN, "Passive")
    field(NELM, "40")
    field(FTVL, "SHORT")
}

if I use caput to write the value to the PV like this:

caput twf 1 2 3 4 5

Old : twf 40 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

New : twf 40 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 

seems the array wasn't written to the PV, why?

 

Thanks a lot in advance.
