parameter value is not possible. For example, Product level value in
device can be directly mapped to CIU Product level value but Gauge
status / Gauge alarms from the device might not directly map to CIU
Gauge status / Gauge alarms and needs a custom value map. Refer to
the following table for more information.

Description
Possible Values
<CustomValueMap>
<CustomValue>
<DeviceParameterName>
This is the device parameter
name as defined in the
Manufacturer's product data
sheet to which we need to
associate the custom value.

<Name>
This indicates the CIU
Parameter Name to which
device parameter is mapped.

<CustomValueMap>
<CustomValue>
<CIUMapDetail>
<ValueMapType>
This indicates the value map
type.
Device parameter's
enumeration to CIU
parameter's enumeration shall
be specified here.
EnumerationToEnume
ration
<CustomValueMap>
<CustomValue>
<CIUMapDetail>
<DefaultValue>
Default Value indicates what
should be the CIU value if
EnumerationToEnumeration is
selected for ValueMapType
and no mapping defined for a
particular device parameter
value
Any value as per CIU
parameter
<CustomValueMap>
<CustomValue>
<CIUMapDetail>
<DeviceParameterStartBitIndex>
<CustomValueMap>
<CustomValue>
<CIUMapDetail>
<DeviceParameterEndBitIndex>
This value indicates the
portion of the device value
which needs to be copied to
the CIU parameter.
For example, if Bits 15 to 8 of
the device parameter needs to
be copied then BitM = 8 and
BitN = 15.
If the entire device value
needs to be copied then this
tag shall be empty
Any value as per
