  I used another PV that does not have a point in it: (Also I used in the caget command "-a" option because they said it prints more info but there was an error as seen below)

cainfo FBH:BCM:NBUNCH.EGU
FBH:BCM:NBUNCH.EGU
    State:            connected
    Host:             130.87.82.88:5064
    Access:           read, no write
    Native data type: DBF_STRING
    Request type:     DBR_STRING
    Element count:    1

labm@labmpc:~$ caget -a BMH:MQC2LE:POS.PXP.EGU
BMH:MQC2LE:POS.PXP.EGU         <undefined> 0 UDF INVALID

This is not an error.

<undefined> 0 says that no value was given to the EGU field of the record.

UDF INVALID is the alarm status and severity for the record.
The alarm info shows that the record was never processed.

Something looks wrong. Why does the EGU field have type DBF_DOUBLE?

Is the problem the . In the record name?

 Dear Bastian, Is still the same:

**************
caget BMH:MQC2LE:POS.PXP.EGU
BMH:MQC2LE:POS.PXP.EGU         0

labm@labmpc:~$ cainfo BMH:MQC2LE:POS.PXP.EGU
BMH:MQC2LE:POS.PXP.EGU
    State:            connected
    Host:             130.87.82.88:5064<http://130.87.82.88:5064>
    Access:           read, no write
    Native data type: DBF_DOUBLE
    Request type:     DBR_DOUBLE
    Element count:    1

I think maybe they did not set the units when they created the PV???

Thank you, Rachid

Dear Rachid,

one way would be to directly request the .EGU field of the PV, i.e.

  caget BMH:MQC2LE:POS.PXP.EGU

All the best
