Re: scalcout EPICS Record Error

[Varuna Crishan Meddage via Tech-talk <tech-talk at aps.anl.gov>]

Hi Andrew,

Thanks

By adding the new .dbd file (GPS_DBD += calcSupport.dbd), I can get rid of this error.

Thanks

These errors aren’t from the values given in your database at all, they are being reported by the scalcout record implementation indicating there was an error in your IOC's build or link stage.

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

The (514,3) above should normally be translated into a string, so your error symbol table isn’t being initialized properly. Then those particular numbers mean S_dev_noDSET: Missing device support entry table.

The scalcout record has a Soft Channel device support (devsCalcoutSoft), but it hasn’t been registered properly in the IOC’s DBD file so the code the record needs to run hasn’t been loaded.

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:
