* @param {Number} objectType - The object type. Both id and enumerated names can be used.
* @param {Number} objectInstance - The object instance. Must be a positive number.
* @param {Number} propertyId - The property id. Both id and enumerated names can be used.
* @return {*} The result can be of any type. It is dependent of the object type and property. Primitive values such as numbers and string but also JSON formatted text.
***********************************************************************************************/
//Reads a present value from analog input object 0.
Controller.readProperty(85343,analogInput,0,presentValue);
//Use the result to print and in logic
res = Controller.readProperty(85343,analogInput,0,presentValue);
print(res);
if ( res > 0 ){
print("value larger than 0!");
}
</code></pre>
h3. *eventSubscribe* - Send request for intrinsic reporting notification to a remote node.
<pre><code class="javascript">
