Set present value to int of hex values

BACnet4J general discussion

    Hi, I have this code:

    systemStatus1 = new BACnetObject(localDevice, localDevice.getNextInstanceObjectIdentifier(ObjectType.analogInput));
systemStatus1.setProperty(PropertyIdentifier.objectName, new CharacterString("System status group 1"));
systemStatus1.setProperty(PropertyIdentifier.units, EngineeringUnits.noUnits);
systemStatus1.setProperty(PropertyIdentifier.presentValue, new Real(65535));
localDevice.addObject(systemStatus1);

    As you can see, I'm inserting a Real with value 65535, which gets translated into 65535.00.
    Is there a way to set a integer value? I've tried with UnsignedInteger
    but I get
    com.serotonin.bacnet4j.exception.BACnetServiceException: class=Property, code=Invalid data type, message=expected class com.serotonin.bacnet4j.type.primitive.Real, received=class com.serotonin.bacnet4j.type.primitive.UnsignedInteger

    Thanks

    Hi Michele,

    I am not an expect on the BACnet4J code, but I do try to dabble and help people a little when I can. But,

    I think you cannot have an UnsignedInteger for a object with the type of AnalogInput. Looking in ObjectProperties suggests the following support a presentValue property set to the UnsignedInteger type:

    ObjectType.
accumulator
command
multiStateInput
multiStateOutput
multiStateValue
positiveIntegerValue

    So it sounds to me like you may be looking for,

    systemStatus1 = new BACnetObject(localDevice, localDevice.getNextInstanceObjectIdentifier(ObjectType.positiveIntegerValue));
systemStatus1.setProperty(PropertyIdentifier.objectName, new CharacterString("System status group 1"));
systemStatus1.setProperty(PropertyIdentifier.units, EngineeringUnits.noUnits);
systemStatus1.setProperty(PropertyIdentifier.presentValue, new UnsignedInteger(65535));
localDevice.addObject(systemStatus1);
