I might be a little slow helping debug it, I'm away from work until July

10. Do the PV names you're trying to access show up in a 'dbl'

command? If so, what shows up when you have the snmp driver do a dump

of them? For example:

snmpr 2 PANDA:LMD:MUPIX:LV:TEST:ReadSwitchOnOff

will do a level-2 debug dump of PV/oid info.

The reason we don't support mbbo/i/direct (yet, anyway) is simply

because the old snmp driver we based on version on didn't support it and

we've never yet needed it. It's something we could add if there's

demand for it (and time is available, you know how that goes).

Hey John, hey all,

we have a Wiener PL506 low voltage power supply in our lab controlled

via SNMP.

I tried using the devSnmp module from NSCL

(https://groups.nscl.msu.edu/controls/)

Nearly everything is working just fine, except for two records:

record (longin, "PANDA:$(subsys):$(dev):LV:$(sector):ReadSwitchOnOff") {
  field( DTYP, "Snmp")
  field( INP,  "@$(CRATE) %{WCR}outputSwitch.$(CH) INTEGER: 100")
}

record (longin,

"PANDA:$(subsys):$(dev):LV:$(sector):ReadRegulationMode__" ) {

  field( DTYP, "Snmp" )

 field( INP, "@$(CRATE) %{WCR}outputRegulationMode.$(CH) INTEGER:

100" )

}

$(CRATE) is the IP-Address of the PL506, %{WCR} = "guru

WIENER-CRATE-MIB::"

and $(CH) is "u0".

When I try to process these records, I get the following error:

epics> dbpf PANDA:LMD:MUPIX:LV:TEST:ReadSwitchOnOff.PROC 1
filename="../dbTest.c" line number=375
No such file or directory - dbPutField error

Any idea what's goning wrong here?

Another question to John: Is there a particular reason why e.g.

mbbi/o(Direct) or bi/o records are not supported by devSnmp?
