Hi,

I'm trying to set some attributes using XML, and I am had problem with some pvs.
Example XML file:

<?xml version="1.0" standalone="no" ?>
<!-- Attributes -->
<Attributes
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
    xsi:noNamespaceSchemaLocation="../../../../../ADCore/XML_schema/NDAttributes.xsd"
   >
    <Attribute name="NumExposures"  	  type="EPICS_PV"    source="CAT:S:cam1:NumExposures_RBV"       datatype="DBR_NATIVE"     description="Number of exposures manufacturer"/>
    <Attribute name="m1_velocity"  	  type="EPICS_PV"    source="CAT:S:m1.VELO"       		datatype="DBR_NATIVE"     description="Motor 1 Velocity"/>
    <Attribute name="photodiode"  	  type="EPICS_PV"    source="CAT:C:RIO03:0215B:ai1       	datatype="DBR_NATIVE"     description="BIM01 - Photodiode"/>
</Attributes>

The two first lines and works fine. The first is a PV from simDetector IOC, (The same IOC where I'm using the HDF5Plugin  and using the XML file). The second is a motorRecord Simulated IOC, that is running in the same host that first ioc.
But, the last one, is returning the value "nan". This specific IOC that provide this PV is running in another host. However, I can read the value using caget:

douglas.araujo@cat-gui:/usr/local/epics/apps/config$ caget CAT:C:RIO03:9215B:ai1
CAT:C:RIO03:9215B:ai1          0.000247466

douglas.araujo@cat-gui:/usr/local/epics/apps/config$ cainfo CAT:C:RIO03:9215B:ai1
CAT:C:RIO03:9215B:ai1
    State:            connected
    Host:             s-cat-c-rio03.abtlus.org.br:5064
    Access:           read, write
    Native data type: DBF_DOUBLE
    Request type:     DBR_DOUBLE
    Element count:    1

I'm using the 3.3.1 ADCore Version.
I read the documentation and saw that this is a behavior when the pv is not connected. But my pv is connected. Need I set some parameter on ioc to get PV from another host ? Or someone have any ideas about this behaivor ??

Regards.
