Hi Vishnu,

You did not show the INP field for the waveform record.  Does each of these waveform records use a different asyn ADDR value?  If so, then you need to remember that asynSetTraceMask takes an ADDR argument, so you can have different asynTrace settings for each ADDR.  I suspect that you have only enabled asynTrace messages on ADDR=0, not for ADDR=1,2,3.

You can either set each address individually:

asynSetTraceMask myPort 0 traceValue
asynSetTraceMask myPort 1 traceValue
asynSetTraceMask myPort 2 traceValue
asynSetTraceMask myPort 3 traceValue

Or you can turn set them all at once using ADDR=-1

asynSetTraceMask myPort -1 traceValue

Note that using the -1 syntax can only be done after iocInit.  This is because using -1 actually goes through all known address and sets their flags, and the addresses actually in use only become known at iocInit.

Mark

Subject: IOC shell message for waveform record

Hi,
   I have 4 PVs
TEST-6368-AI05:AIW00
TEST-6368-AI05:AIW01
TEST-6368-AI05:AIW02
TEST-6368-AI05:AIW03
 reading different channels and configured in same way with
      field(DTYP, "asynFloat32ArrayIn")
      field(SCAN, "I/O Intr")
      field(NELM, "10")
      field(FTVL, "FLOAT")
      info(FIFO, "60")
. But i am getting below message on IOC shell  for only one PV each time it callback IO interrupt.

 2015/03/05 20:27:43.424 TEST-6368-AI05:AIW00 devAsynFloat32Array::interruptCallbackInput ringSize=60, len=10, callback data:2015/03/05 20:27:43.424 TEST-6368-AI05:AIW00 devAsynFloat32Array::processCommon nord=10, pwf->bptr data:

what could be the reason for this messages?

Thank you
Vishnu
