OPC UA Client samplingInterval parameter seems not take any effect

When I set the samplingInterval  parameter on a Milo OPC UA Client route, the interval not changes on the real OPC application! Remains 1000 mili seconds even after configuring!! Can anyone confirm that??

 Heres my route

<routes xmlns="http://camel.apache.org/schema/spring" >
    <route id="sensor">

        <from uri="milo-client:tcp://192.168.0.2:4840?samplingInterval=50&node=RAW(ns=4;i=12)"/>
        <process ref="set-opc"/>
        <setBody><simple>${in.body}</simple></setBody>
        <to uri="stream:out"/>
    </route>
</routes>

Thanks
