Hello,
I have a waveform record with 4 elements with ftvl=USHORT. How to read a single element from waveform using subArray or acalcout record or any other record. I have tried using subarray as
record(waveform, optoRead) {
field(SCAN, "Passive")
field(NELM, "4")
field(FTVL, "USHORT")
field(DTYP, "wafoptosupport")
field(FLNK, "optolinks")
}
record(subArray, opto1) {
field(SCAN, "Passive")
field(DTYP, "Soft Channel")
field(FTVL, "USHORT")
field(INP, "optoRead")
field(INDX, "0")
field(FLNK, "opto1Binary")
field(MALM, "2")
field(NELM, "1")
}
record(subArray, opto2) {
field(SCAN, "Passive")
field(DTYP, "Soft Channel")
field(INP, "optoRead")
field(MALM, "4")
field(INDX, "1")
field(FLNK, "opto2Binary")
field(FTVL, "USHORT")
field(NELM, "1")
}
record(subArray, opto3) {
field(SCAN, "Passive")
field(DTYP, "Soft Channel")
field(INP, "optoRead")
field(MALM, "4")
field(INDX, "2")
field(FLNK, "opto2Binary")
field(FTVL, "USHORT")
field(NELM, "1")
}
record(subArray, opto4) {
field(SCAN, "Passive")
field(DTYP, "Soft Channel")
field(INP, "optoRead")
field(MALM, "4")
field(INDX, "3")
field(FLNK, "opto2Binary")
field(FTVL, "USHORT")
field(NELM, "1")
}
but it doesn't works. Everytime on doing caget it prints just the first element of waveform.
