Re: database method to copy string to char waveform

["Johnson, Andrew N. via Tech-talk" <tech-talk at aps.anl.gov>]

You can also use a long string output (lso) record to copy a string into a waveform or vice versa. This works for me, and will similarly require 3.15 or later:

record(stringout, "so") {

  field(VAL, "This is another string")

}

record(waveform, "wf") {

  field(NELM, 100)

  field(FTVL, CHAR)

}

record(lso, "xerox") {

  field(DOL, "so")

  field(OMSL, "closed_loop")

  field(OUT, "wf")

}

You can swap the DOL and OUT links to copy in the other direction.

Hi Malte,

Using current 3.15 or EPICS 7, this database:

record (waveform, "wf") {

  field(NELM, "100")

  field(FTVL, "CHAR")

  field(INP, "so.VAL$")

}

record (stringout, "so") {

  field(VAL, "this is a string")

}

does that job for me. Or did I get the problem wrong?

Cheers,
