Dear all,

 

I have got installed a TME - Ethernet Thermometer, (http://www.papouch.com/en/shop/product/tme-ip-ethernet-thermometer/) which supports SNMP protocol, and I would like to read the temperature using EPICS with devSnmp.

 

My simple database is

record(ai, "TME:TempTimes10")

{

    field(DESC, "TME Temperarature sensor")

    field(DTYP, "Snmp")

    field(INP,  "@192.168.58.96 public  SNMPv2-SMI::enterprises.18248.1.1.1.0  Float: 100")

    field(EGU,  "degrees C")

    field(LINR, "LINEAR")

    field(SCAN, "1 second")

    field(HIHI, "250")

    field(HHSV, "MAJOR")

 

}

 

The ioc runs ok without errors,  but with caget I only get 0 as temperature’s value, and with camonitor I get the value is INVALID

 

-bash-4.1$ camonitor TME:TempTimes10

TME:TempTimes10                2014-05-06 16:43:11.479828 0 READ INVALID

 

 

I posted a similar question a while ago for a different monitor, and at that time I solved  the problem using an OID name as given back from snmpget, but this solution does not work this time.

 

-bash-4.1$ snmpget -v1 -c public 192.168.58.96 1.3.6.1.4.1.18248.1.1.1.0

SNMPv2-SMI::enterprises.18248.1.1.1.0 = INTEGER: 182

-bash-4.1$

The OID name seems to be ok, so I cannot understand why I keep obtaining 0 as a value from caget, and I can get right value from snmp.

 

The same ioc works ok with a different module and with the following database

record(ai, "TCW122B:Temp1Times10")

 

{

    field(DESC, "Temperarature sensor 1")

    field(DTYP, "Snmp")

    field(INP,  "@145.239.84.45 public SNMPv2-SMI::enterprises.38783.3.9.0  INTEGER: 100")

    field(EGU,  "degrees C")

    field(LINR, "LINEAR")

    field(SCAN, "1 second")

    field(HIHI, "250")

    field(HHSV, "MAJOR")  

}

 

Could anyone help me to understand why I get always 0 using caget but I get right value from snmpget?

Thank you very much.

Kind regards,

Nicoletta
