Hi,

I am a bit confused by the following behavior.

I am using EPICS R3.14.12.2 and asyn R4.20.

I have a simple longout record:

record( longout, "$(P):$(N):LO:BTOI:NCOEF"){

  field( DESC, "N Coefs:")

  field( DTYP, "asynInt32")

  field( OUT,  "@asyn($(PORT),$(N),1)LO_NCOEF")

 field( VAL,  "2")

  field( PINI, "1")

}

After this record is done initializing, caget on it gives me 0.

I have introduced another record as follows:

record( longout, "$(P):$(N):LO:NCOEF"){

  field( DESC, "N Coefs:")

  field( VAL,  "2")

  field( OUT,  "$(P):$(N):LO:BTOI:NCOEF PP")

  field( PINI, "1")

}

record( longout, "$(P):$(N):LO:BTOI:NCOEF"){

  field( DESC, "N Coefs:")

  field( DTYP, "asynInt32")

  field( OUT,  "@asyn($(PORT),$(N),1)LO_NCOEF")

# field( VAL,  "2")

#  field( PINI, "1")

}

With these two records the second one now has the correct value.

Why does the single record solution lose its VAL value?

Thanks in advance,

Zen
