Re: scalcout EPICS Record Error

[Mark Rivers via Tech-talk <tech-talk at aps.anl.gov>]

I have never seen an error like:

recGblRecordError: scalcout:init_record Error (514,3) PV: PIP2:TIME_CTRL_GPS:calc_nsChannel1Vrms

I don't know what the (514,3) means. 

It seems like it could be a problem with missing device support or something.

Can you send the complete output when the IOC boots.

Mark

Hi Mark,

Thanks for the suggestion,

I implemented what you have suggested as follows.

======================================================

record(stringin, "$(acc):$(sys)_$(group):nsChannel$(channel_id)Vrms")

{

  field(SCAN, "10 second")

  field(DTYP, "Snmp")

  field(INP, "@$(HOST) $(COMMUNITY) $(W)::nsChannel$(channel_id)Vrms.0 STRING: 100")

  field(DESC, "Channel $(channel_id) Vrms")

  field(FLNK, "$(acc):$(sys)_$(group):calc_nsChannel$(channel_id)Vrms")

}

record(scalcout, "$(acc):$(sys)_$(group):calc_nsChannel$(channel_id)Vrms")

{

  field(INAA, "$(acc):$(sys)_$(group):nsChannel$(channel_id)Vrms")

  field(CALC, "LEN(AA)==0?0:DBL(AA)")

  field(PREC, "2")

  field(EGU, "V")

  field(DESC, "Channel $(channel_id) Vrms")

}

============================================================

But still get the following error messages in runtime.

Whoops the DBL argument should be AA too:
