I'm trying to initialise an analog output record
by putting a constant in the DOL field (see below).

But the VAL field gets set to zero rather than 100.
The record does process and outputs this zero.

I can work around this by Initialising from another record
using clsed loop mode but it does seem to be a bit of a cludge
(see commented out lines).

What am I doing wrong?

record(ao, "$(device):SETSIZE") {
    field(DESC, "Pump Size")
    field(DTYP, "ornlSerial")
    field(OUT,  "@digitel mpc size p=1 u=$(port) m=$(unit) p1=$(pump)")
    field(PINI, "YES")
    field(DOL,  "100.0")
#    field(DOL,  "$(device):INITSIZE")
#    field(OMSL, "closed_loop")
    field(EGU,  "l/s")
    field(DRVL, "0.0")
    field(DRVH, "1200.0")
    field(LOPR, "0.0")
    field(HOPR, "1200.0")
    field(PREC, "0")
}
record(ai, "$(device):INITSIZE") {
    field(VAL, "200.0")
}
