Hi,

 

Load this into your IOC:

record(waveform, "cawave")
{
    field(DESC, "numeric array")
    field(NELM, "20")
    field(FTVL, "DOUBLE")
}

 

>>> import CaChannel

>>> pv=CaChannel.CaChannel('cawave')
>>> pv.searchw()
>>> pv.getw()
[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]
>>> pv.putw(range(12))
>>> pv.getw()
[0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0, 11.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0]

Dear Sir,

Could I get an example of how to handle sub array and waveforms records in CaChannel-v1.6 library code.

Best regards,
