epics snmp

Hi，

I'm trying to control the device using the SNMP protocol and the db file is as follows:

 

record(ai,"$(DEV):Current")

{

    field(DESC,"SNMP channel")

    field(DTYP,"Snmp")

    field(SCAN,".2 second")

    field(PREC,"3")

    field(INP,"@$(HOST) public $(MIB)::pduInputPhaseSTATUSCurrent.1.1 Float 100")

}

 

The st.cmd file are as follows:

< envPaths

 

epicsEnvSet("EPICS_CA_SERVER_PORT", 6310)

epicsEnvSet("EPICS_PVA_SERVER_PORT", 6710)

epicsEnvSet("MIBDIRS", "+$(TOP)/mibs:/usr/local/share/snmp/mibs")

epicsEnvSet("IOCNAME","npdu")

cd "${TOP}"

## Register all support components

dbLoadDatabase "dbd/npdu.dbd"

npdu_registerRecordDeviceDriver pdbbase

devSnmpSetSnmpVersion(192.168.0.1:161,SNMP_VERSION_1)

devSnmpSetMaxOidsPerReq(192.168.0.1:161,50)

dbLoadRecords "db/dbpdux.db", "DEV=TEST, HOST=192.168.0.1, MIB=ENLOGIC-PDU-MIB"

cd "${TOP}/iocBoot/${IOC}"

iocInit

But there is an error:

 caget TEST:Current

Channel connect timed out: 'TEST:Current' not found.

If there is no error in the DB, the device is not connected, is there an error in the st.cmd file?

Thanks,

White
